Provedor de dados: 32
Autores: Pérez Estrada, Víctor Manuel.
El trabajo consistió en dos fases, la primera fue en invernadero y la segunda en campo. En  invernadero se evaluó la influencia de dos regímenes de humedad del suelo [80 a 100 y 40  a 60 % de la capacidad máxima de retención de agua del sustrato (CMRAS)] y la  inoculación con tres hongos ectomicorrízicos comestibles, Hebeloma spp., Laccaria spp. y  Clavulina aff. cinerea, así como sus interacciones, en el desarrollo de dos especies de  pinos: Pinus patula Schl. et Cham y Pinus hartwegii Lindl. En las plantas de Pinus patula  inoculadas con Hebeloma spp., el régimen de humedad de 80 a 100 % de la CMRAS  produjo mayor peso seco total (46 %) y altura (25 %) en comparación con el régimen de  humedad de 40 a 60 % de la CMRAS. En Pinus patula inoculado con...

Antimicrobiales para el control de hongos en una dieta artificial y su impacto en la supervivencia y reproducción de Spodoptera frugiperda (J. E. Smith).
Provedor de dados: 32
Autores: Zambrano Gutiérrez, Jorge.
Las dietas artificiales son importantes para establecer crías de insectos bajo condiciones controladas de laboratorio. Sin embargo, en estas condiciones también pueden la contaminación de las dietas con hongos. Para evitar la contaminación de las dietas de insectos se utilizan antimicrobiales que en algunas ocasiones ya están presentes en la dieta o bien se deben agregar a ésta. En el laboratorio de Toxicología de Insecticidas la dieta artificial BioServ Inc., Frenchtown, NJ. se contaminaba con hongos. Así mismo se observó que al controlar la contaminación, ésta se podría utilizar en la cría masiva de Spodoptera frugiperda. El objetivo general del presente trabajo fue estimar la supervivencia, reproducción, duración del ciclo de vida, peso de larvas de...

Estudio comparativo de Dendroctonus valens y D. rhizophagus (Curculionidae: Scolytinae) y sus hongos asociados.
Provedor de dados: 32
Autores: León García, Norma.
En el presente trabajo se realizó una comparación morfológica de Dendroctonus valens y D. rhizophagus, las cuales son especies muy similares morfológicamente y esto dificulta la identificación adecuada y por lo tanto la separación de las especies. Lo anterior es importante cuando se requiere dar manejo a las plagas forestales debido a que cuando se desea aplicar algún tipo de control es importante conocer e identificar adecuadamente de qué especie se trata. El objetivo principal para este estudio fue realizar una comparación de las características morfológicas diferenciales externas e internas de ambas especies que ayuden a la identificación adecuada de las mismas, además de aislar sus hongos asociados y estudiar el sistema de galerías para estos...

Propagación in vitro y convencional de tres especies de bambú.
Provedor de dados: 32
Autores: Lárraga Sánchez, Noé.
Las condiciones fisiográficas y climáticas de México son apropiadas para la propagación y producción de bambú en todo el país. Sin embargo, su aprovechamiento comercial tiene dificultades porque los métodos comunes de propagación son lentos o poco viables. La propagación por semilla se descarta porque la mayoría de las especies de bambú tienen periodos juveniles de hasta 70 años, su floración es impredecible y su semilla recalcitrante. En cuanto a la propagación vegetativa, no existen suficientes centros de producción de plántula de buena calidad y en las cantidades requeridas. Sólo en Puebla se requieren al menos 20 000 ha para producir 1 000 t diarias de papel. Por lo anterior, es necesario desarrollar metodologías de propagación que permitan satisfacer...

Provedor de dados: 69
Autores: Romero-Noguera,Julio; Martín-Sánchez,Inés; López-Miras,María del Mar; Ramos-López,José Miguel; Bolívar-Galiano,Fernando.
Since the middle of the XIX century, when dammar became popular in Occident, this natural resin is one of the most used in art painting techniques as final protective coating (varnish) as well as a component of pictorial media. The present work is the first approach to the study of the microbiological biodeterioration of this artistic material, which can seriously affect the appearance and integrity of works of art when bad conservation conditions -especially high humidity levels- take place. 12 microorganisms, fungi and bacteria, came from collection and from oil paintings affected by biodeterioration patterns, were inoculated on test specimens prepared with varnish dammar. These were incubated and analyzed by GC-MS to determine both the microbiological...

An approach to the study of the fungal deterioration of a classical art material: Mastic varnish
Provedor de dados: 69
Autores: Romero-Noguera,Julio; López-Miras,María del Mar; Martín-Sánchez,Inés; Ramos-López,José Miguel; Bolívar-Galiano,Fernando.
Mastic, one of the best natural varnishes, is frequently used as protective and finishing layer or as component of oleo-resinous media in paintings, both in the past and currently. However, this resin is affected by complex deterioration processes which can change its characteristics and thus the visual aspect of works of art. The alteration processes caused by radiation have been widely studied, but there is a lack of information on the biodeterioration of this natural product. In this paper, fungi from collections as well as from oil paintings of the Fine Arts Museum of Granada (Spain) were inoculated onto slides covered with mastic. The samples, after an incubation period of 15 days, were analysed by gas chromatography-mass spectrometry (GC-MS) to...

Culturable fungi associated with urban stone surfaces in Mexico City
Provedor de dados: 69
Autores: Páramo-Aguilera,Leandro; Ortega-Morales,Benjamín Otto; Narváez-Zapata,José Alberto.
Background: Urban surface stones in Mexico City are exposed to a temperate climate and a range of atmospheric conditions ranging from mildly impacted to heavily polluted areas. In this study, we focused on the characterization of the cultivable fungal component of selected biological patinas in the surrounding area of Chapultepec castle, a historic monument in Mexico City. Thirty four representative fungal isolates selected based on distinctive differential macroscopic characteristics out of a total of 300 fungi, were characterized using morphological and molecular approaches. Results: This identification strategy based on the combination of phenotypic- and molecular-based methodologies allowed us to discriminate the fungal community in some cases down to...

First record of flamentous fungi in the coastal upwelling ecosystem off central Chile
Provedor de dados: 72
Autores: Gutiérrez,Marcelo H; Pantoja,Silvio; Quiñones,Renato A; González,Rodrigo R.
We report for the frst time the presence of flamentous fungi in the water column and sediment in the coastal upwelling ecosystem off central Chile, using molecular tools and epifuorescence microscopy. Positive amplifcations of SSU 18s rDNA with specifc fungal primers were obtained for surface waters and sediments of this coastal ecosystem. Molecular richness obtained from denaturing gradient gel electrophoresis showed a higher number of fungal genotypes in nearshore than offshore sites and in summer than winter. Fungal structures identifed by epifuorescence microscopy in the water column were present as individual flaments or as aggregates of hyphae. We show for the frst time vertical water column profles of fungal biomass in the marine ecosystem. Fungal...

In silico characterization of microRNAs-like sequences in the genome of Paracoccidioides brasiliensis
Provedor de dados: 74
Autores: Curcio,Juliana S. de; Batista,Mariana P.; Paccez,Juliano D.; Novaes,Evandro; Soares,Célia Maria de Almeida.
Abstract Eukaryotic cells have different mechanisms of post-transcriptional regulation. Among these mechanisms, microRNAs promote regulation of targets by cleavage or degradation of the mRNA. Fungi of the Paracoccidioides complex are the etiological agents of the main systemic mycosis of Latin America. These fungi present a plasticity to adapt and survive in different conditions, and the presence of microRNAs-like molecules could be part of the mechanisms that provide such plasticity. MicroRNAs produced by the host influence the progression of this mycosis in the lungs besides regulating targets involved in apoptosis in macrophage, activation of T and B cells and the production of cytokines. Therefore, this work analyzed the presence of regions in the...

Synthetic and minimalist vectors for Agrobacterium tumefaciens-mediated transformation of fungi
Provedor de dados: 74
Autores: Nora,Luísa Czamanski; Gonçales,Relber Aguiar; Martins-Santana,Leonardo; Ferreira,Beatriz Henriques; Rodrigues,Fernando; Silva-Rocha,Rafael.
Abstract We present a collection of minimalist binary vectors for transformation through ATMT applicable to several fungi species. pLUO plasmid binary vectors consist of a reporter module containing fluorescent proteins, mCherry or eGFP, flanked by a multiple cloning site and a transcription terminator site. They also present a synthetic gene allowing resistance to Hygromicin B flanked by alternate promoters, one for yeast and another for filamentous fungi. Left and right borders were added for Agrobacterium tumefaciens recognition, and a minimal broad-host range RK2 replication origin. Transformation was validated in the pathogenic fungus Paracoccidioides lutzii. Hence, we developed an efficient and reliable molecular tool for fungal transformation:...

An analysis of the spontaneous mutation rate measurement in filamentous fungi
Provedor de dados: 74
Autores: Baracho,Marta S.; Baracho,Ivanhoé R.
Mutations related to gene methG1 of Aspergillus nidulans were analyzed, in order to study a mathematical model for the determination of the mutation rate per nucleus per generation, in filamentous fungi. A replica plating technique was used to inoculate, in a single operation, 26 colonies of the strain, into Petri dishes containing culture medium, and the nine central colonies were analyzed for size and number of conidia in each colony. Using this technique, several central colonies were analyzed with regard to the appearance of mutation, and the number and type of reversions were determined for each colony. The frequencies obtained for each reversion were analyzed, in order to verify if their distribution was in accordance with that of Greenwood and Yule....

Autores: Смирнова, Л. Л.
Исследована сезонная динамика численности гетеротрофных бактерий и микромицетов, участвующих в разрушении органического вещества в различных биотопах б. Казачья. Показано, что численность гетеротрофных бактерий в 100 – 1000 раз превышает таковую грибов в морской пене, поверхностном микрослое воды и донных отложениях. Низкая солёность, повышенное содержание органического вещества и возрастание соотношения C/N ≥20 благоприятны для развития микобиоты в донных отложениях. Из исследованных биотопов выделено 44 вида микромицетов, отнесённых к митоспоровым грибам (Deuteromycetes). В поверхностном микрослое воды доминировал Cladosporium cladosporioides, в донных отложениях часто встречались представители родов Aspergillus, Penicillium, Phoma, Mucor.

Todos os anos, com a chegada das chuvas, as cigarrinhas-das-pastagens, principal praga que ataca os capins tropicais, começam a causar transtornos para os pecuaristas. Em alguns anos, notadamente após um período seco mais pronunciado, a incidência e a severidade dos ataques costumam ser mais intensas, o que pode causar a morte de capins suscetíveis e a degradação da pastagem. Isso exige atenção por parte de toda a equipe da fazenda, que deve estar preparada para reconhecer o problema e combater a praga. A estratégia mais importante para amenizar os problemas causados por essa praga é a diversificação das pastagens na fazenda, com o plantio de capins tolerantes e resistentes.

"Aids" do marandu tem raízes na umidade do solo.
Provedor de dados: 14
Autores: VALENTIM, J. F.
Quando gostam de um capim, os pecuaristas costumam lhe conferir falsa "universalidade", plantando-o até mesmo em regiões inadequadas a seu cultivo. Foi o que aconteceu com a Brachiaria brizantha cultivar Marandu, lançada pela Embrapa em 1984 e batizada popularmente de braquiarão. Produtiva, rústica e de fácil manejo, ela tornou-se uma das "coqueluches" da pecuária nas últimas décadas e hoje constitui verdadeira monocultura, ocupando cerca de 60 milhões de hectares no Centro-Oeste e Norte do País.

Cerca de 46 patogenos (fungos, bacterias, virus e nematoides) sao relatados como transmissiveis atraves de sementes de soja. No brasil, a maioria destes patogenos ja foram listados. Cerca de 14 destes microorganismos, alem de causarem danos a sementes e plantulas, podem tambem servir como fonte inicial de inoculo em novas areas de cultivo. Uma vez estabelecidos, estes patogenos irao causar doencas nas partes aereas da cultura (caule, folhas, vagens e sementes), contribuindo para reducao da produtividade e dando origem, por sua vez, a sementes infestadas com altos indices de patogenos. No brasil Central (regiao dos Cerrados do Distrito Federal, Goias, Mato Grosso do Sul e Mato Grosso), sao encontrados com frequencia pelo menos 6 destes...

Micorrizas são associações de natureza mutualistícas formadas entre fungos do solo e raízes das espécies vegetais. Segundo Harley e Smith, o seu caráter mutualista contribui para sobrevivência e evolução das plantas terrestres e dos fungos, pois o fungo simbionte aumenta a capacidade da planta de absorver nutrientes do solo, principalmente o fósforo, favorecendo sua nutrição enquanto a planta fornece fotossintatos para o fungo que é incapaz de realizar fotossintese.Entre tais associações encontram-se as micorrizas arbusculares (MA), pertenentes à classe dos Zygomycetes, ordem Glomales.

Os microorganismos do solo estao presentes em grande numero proximo as raizes das plantas e desempenham um papel importante em numerosos processos fisiologicos, que compreendem a patogenicidade, o saprofitismo e a simbiose. A simbiose mais amplamente observada entre as plantas e a associacao micorrizica, que envolve varios fungos do solo e raizes de plantas superiores. Esta associacao micorrizica, ou micorriza, tornou-se um tema de pesquisa de interesse desde que foi constatada a sua capacidade de proporcionar um aumento da absorcao de nutrientes do solo pelas plantas, principalmente do fosforo. As micorrizas nao aumentam o teor total de nutrientes no solo, mas permitem que a planta explore melhor as suas reservas. Nos olos de baixa fertilidade, a...

Bertholletia excelsa Bonpl., também conhecida como castanheira-do-brasil, castanheira-do-pará e castanheira-da-amazônia, é uma árvore que ocorre naturalmente em grande parte da Amazônia. Entretanto, a presença de aflatoxinas B1, B2, G1 e G2 de Aspergillus spp. em amostras de castanha-do-brasil com casca e sem casca, em níveis superiores àqueles considerados seguros por países importadores, tem limitado as exportações desse produto, além de restringir o mercado interno. A presença dessas aflatoxinas nas castanhas depende da infecção e colonização dos tecidos da semente por fungos Aspergillus spp. Níveis de fatores ambientais próximos aos favoráveis à produção de aflatoxinas são encontrados na Floresta Amazônica, durante a época de queda dos frutos e...

A sigatoka-negra, causada por Mycosphaerella fijiensis Morelet, é a doença mais importante para a cultura da bananeira no mundo, atingindo as principais variedades cultivadas, reduzindo significativamente a produção, afetando a qualidade dos frutos e elevando o custo de produção nos países onde o controle químico é realizado. A doença foi constatada no Brasil em fevereiro de 1998, estando hoje disseminada por toda a Região Norte e Estado do Mato Grosso. No Acre, foi constatada em dezembro de 1998, afetando severamente todas as variedades de banana, principalmente as do subgrupo Terra, que são as mais plantadas no Estado. Devido à sigatoka-negra, em 2001, verificou-se uma redução de 42% da área cultivada com essa cultura, repercutindo na menor geração de...

Patogenicidade de isolados de fusarium sacchari de mangueira do Cerrado do Brasil Central.
Provedor de dados: 14
Autores: ANJOS, J. de R. N. dos; CHARCHAR, M. J. d'A.
ABSTRACT: The fungus Fusarium sacchari (E.J. Butler &amp; Hafiz Kahn) W. Gams, was consistently isolated from infected malformed shoots and panicles of mango in the Cerrado Region of Central Brazil, from 1998 to 2000. Pathogenicity tests of the F. sacchari isolates were carried out on potted six month-old Tommy Atkins seedlings by introducting a PDA disk with fungal mycelium and conidia in a vertical slit at the tip. F. sacchari is almost completely restricted to shoot tissues in malformed trees. The levels of colonization are highest in malformed vegetative and floral shoots and are much lower in asymptomatic shoots. Treatment of mango malformation with fungicides is ineffective. The only viable control option is the removal and burning of the affected...

Sombreamento para controle da Antracnose na produção de mudas de açaí-solteiro.
Provedor de dados: 14
Autores: NOGUEIRA, S. R.; ANDRADE NETO, R. de C.; LUNZ, A. M. P.
O açaí-solteiro (Euterpe precatoria Mart.) é uma palmeira nativa do Estado do Acre, sendo a produção de polpa oriunda do extrativismo. A procura pelo produto é grande e crescente no Brasil e no mundo, estimulando plantios comerciais. No entanto, poucas são as informações sobre a produção de mudas em viveiros e cultivo dessa espécie. Muitas técnicas usadas no seu cultivo, provenientes de recomendações para o açaí-de-touceira (E. oleracea), nem sempre são as mais adequadas, a exemplo do melhor nível de sombreamento para produção de mudas. Principalmente no viveiro o açaí-solteiro é bastante atacado pela antracnose, doença fúngica, causada por Colletrotrichum gloesporiodes, que ocasiona manchas e seca das folhas, levando a altas taxas de mortalidade das...

Plantio direto do feijão na palha do arroz: alternativa para controle da "Mela do Feijoeiro".
Provedor de dados: 14
Autores: CAMPOS, I. S.; GOMES, T. C. de A.; PAZ, F. das C. A.
A doença conhecida como Meia do Feijoeiro", causada pelo fungo de solo (Thanatephorus cucumens), é um dos fatores limitantes da cultura do feijão (Phaseolus vulgaris) na região amazônica. A produtividade obtida no Estado do Acre, nos últimos anos, não ultrapassou 600 Kg/ha. Nesta região, as lavouras tradicionalmente implantadas na segunda quinzena de março e início de abril, geralmente, são atacadas pela "Mela» com perda total da produção. Mesmo quando as plantas chegam a frutificar, os grãos são danificados pela doença. Agricultores que plantam um pouco mais tarde, conseguem colheitas razoáveis. Entretanto, o plantio tardio tem provocado muitas perdas devido a falta de chuvas por ocasião da floração do feijão. Com o impacto da chuva o fungo presente no...

Autores: SOUZA, J. M. L. de; CARTAXO, C. B. da C.; LEITE, F. M. N.; REIS, F. S.
Nativa da Região Amazônica, a castanheira (Bertholletia excelsa H.B.K.) é considerada uma das maiores riquezas nos estados que formam a Amazônia Brasileira. Um dos grandes problemas na conservação da castanha-do-brasil deve-se ao crescimento de fungos produtores de aflatoxinas e bactérias patogênicas, por causa das condições de umidade relativa e temperatura elevadas a que é submetida desde o momento da queda do ouriço. Assim, buscou-se identificar, em indústrias de processamento de castanha-do-brasil no Acre, os microrganismos responsáveis pela qualidade sanitária, especialmente os do grupo coliformes, bactérias mesáfilas, bolores e leveduras. Foram coletadas amostras nos meses de agosto de 2001 a maio de 2002, em cinco etapas do processamento. As...

A banana é considerada a principal fruteira do Estado do Acre, ocupando uma área de 7 mil hectares e produtividade média de mil cachos/ha/ano. Em 2002, dentre as principais culturas permanentes cultivadas no Acre, a banana se destacou com 52% da área plantada, seguida da pupunha para palmito (15%). A cultura tem um papel importante na subsistência de milhares de famílias no Estado. A maior parte da produção é comercializada em mercados locais e nos Estados de Rondônia, Amazonas e Goiás. A renda obtida é destinada à compra de produtos industrializados e outros alimentos não produzidos na propriedade. Embora com boa produtividade para as condições da Amazônia, o sistema de exploração atual de bananeira na região é bastante rústico, caracterizado pelo baixo...

Durabilidade de estacas de eucalipto (Eucalyptus sp.) tratadas com CCA após 60 meses de ensaio no campo experimental da Embrapa Acre, Rio Branco, Acre.
Provedor de dados: 14
Autores: ARAUJO, H. J. B. de; MAGALHAES, W. L. E.; OLIVEIRA, L. C. de; SA, C. P. de; CORREIA, M. F.
Atualmente, no Acre, o preço das estacas tratadas de eucalipto para cercados é bastante competitivo como das estacas de espécies nativas tradicionalmente utilizadas em contato com o solo, mesmo considerando os custos do tratamento preservativo e do transporte do centro-sul do país, pois não há no estado plantios dessa espécie e tampouco unidades industriais (usinas) de preservação. Outro aspecto vantajoso do uso de espécies plantadas e tratadas em substituição às tradicionais é de ordem ambiental, uma vez que a pressão exploratória sobre as espécies nativas será reduzida, o que é muito positivo do ponto de vista de conservação e recomposição dos estoques naturais. O presente estudo objetiva avaliar o grau de degradação de organismos xilófagos, fungos e...

Autores: MIRANDA, J. C. C. de; FIALHO, J. de F.; MIRANDA. L. N. de.
ABSTRACT: Cassava plants are highly dependent on arbuscular mycorrhiza for its optimum growth. Its cultivation in cerrado soil requires soil and culture management as soil liming and fertilization and crop rotation. Though, higher plant growth and root yield are attained and applied inputs are better usen when the cassava plants are mycorrhizal. The adequate liming and fertilization procedures and rotational crop sequences, improve the native community of those fungi in the soil, in quantity and quality, by favoring the re-establishment of species efficient for the crop. Mycorrhiza contribution to cassava growth and root production occurs even in soils well fertilized, resulting in higher productivity.

Background. Hemocyanins are respiratory proteins with multiple functions. In diverse crustaceans hemocyanins can release histidine-rich antimicrobial peptides in response to microbial challenge. In penaeid shrimp, strictly antifungal peptides are released from the C-terminus of hemocyanins.  Methods. The three-dimensional structure of the antifungal peptide PvHCt from Litopenaeus vannamei was determined by NMR. Its mechanism of action against the shrimp pathogen Fusarium oxysporum was investigated using immunochemistry, fluorescence and transmission electron microscopy.  Results. PvHCt folded into an amphipathic α-helix in membrane-mimicking media and displayed a random conformation in aqueous environment. In contact with F. oxysporum, PvHCt bound...

The deep subseafloor, extending from a few centimeters below the sediment surface to several hundred meters into sedimentary deposits, constitutes the deep biosphere and harbors an unexpected microbial diversity. Several studies have described the occurrence, turnover, activity and function of subseafloor prokaryotes; however, subsurface eukaryotic communities still remain largely underexplored. Ribosomal RNA surveys of superficial and near-surface marine sediments have revealed an unexpected diversity of active eukaryotic communities, but knowledge of the diversity of deep subseafloor microeukaryotes is still scarce. Here, we investigated the vertical distribution of DNA and RNA fungal signatures within subseafloor sediments of the Canterbury basin (New...

Autores: Donald, Julian; Roy, Mélanie; Suescun, Uxue; Iribar, Amaia; Manzi, Sophie; Péllissier, Léonie; Gaucher, Philippe; Chave, Jérôme.
1.Community assembly theory assumes that ecological communities are spatially delimited into patches. Within these patches, coexistence results from environmental filtering, competition, and immigration. Truly delineated communities exist in laboratory studies of microbial cultures in Petri dishes, yet empirical tests conducted in continuous environments often use patches defined by convention as opposed to realised boundaries. 2.Here we perform a test of ecological community assembly rules using foliar endophyte communities from a tropical rainforest, where leaves are considered as patches for both fungal and bacterial communities. We determined the diversity of fungal and bacterial endophytes using environmental DNA sequencing of 365 top‐canopy leaves,...

Sediment samples were collected at monthly intervals, from 4 stations and analysed microbiologically. In general, bacterial population was found to be dominant followed by actinomycetes and fungi. The max peak for TMP, THB and fungi were recorded in Nov. in all stations. Monsoon season supported TMP, THB and fungi to a high level and it was summer for actinomycetes. Statistical analysis (Kendall's tau) showed a significantly positive correlation among TMP, THB, actinomycetes...

EFFECTIVENESS OF THE APPLICATION OF ARBUSCULAR MYCORRHIZA FUNGI AND ORGANIC AMENDMENTS TO IMPROVE SOIL QUALITY AND PLANT PERFORMANCE UNDER STRESS CONDITIONS
Provedor de dados: 126
Autores: Medina,Almudena; Azcón,Rosario.
Plant growth is limited in arid and/or contaminated sites due to the adverse conditions coming from heavy metal (HM) contamination and/or water stress. Moreover, soils from these areas are generally characterised by poor soil structure, low water-holding capacity, lack of organic matter and nutrient deficiency. In order to carry out a successful re-afforestation, it is necessary to improve soil quality and the ability of plants species to resist this harsh environment. The symbiosis with arbuscular mycorrhizal (AM) fungi has been proposed as one of the mechanisms of plant heavy metal tolerance and water stress avoidance. On the other hand, addition of organic amendments to the soil can reverse degradation of soil properties. Agro-waste residues such as dry...

Provedor de dados: 80
Autores: Perestrelo,M. F.; Norberg,A. N.; Guerra-Sanches,F.; Torres,A. C.; Pile,E.
Water used in hydrotherapy units of Nova Iguaçu and Nilópolis, Rio de Janeiro State, Brazil, was microbiologically analyzed. Thirty samples (5ml each) were weekly collected from September 2001 to June 2002 before the beginning and after the end of activities in the units. For analysis, routine techniques were used, which showed the presence of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp, Candida spp, Penicillium spp, Epidermophyton spp, Aspergillus fumigatus, Aspergillus niger, Aspergillus spp, Cephalosporium spp, Cladosporium spp, Trichophyton rubrum, and Trichophyton spp. Results indicated a need for improving hygienic conditions, suggesting that water might be a contamination source in the evaluated units.

Characterization of a Basidiomycete Fungus from Stored Sugar Beet Roots
Provedor de dados: 18
Autores: Toda, T; Strausbaugh, C.A.; Rodriguez-Carres, M; Cubeta, M.A.
Eighteen isolates sampled from sugar beet roots associated with an unknown etiology were characterized based on observations of morphological characters, hyphal growth at temperatures ranging from 4 to 28 C, production of phenol oxidases, and sequence analysis of internal transcribed spacer (ITS) and large subunit (LSU) regions of the ribosomal DNA (rDNA).  The isolates did not produce asexual or sexual spores, had binucleate hyphal cells with clamp connections, grew from 4 to 22 C with and estimated optimal growth at 14.5 C, and formed a dark brown pigment on potato dextrose or malt extract agar amended with 0.5% tannic acid. Color changes observed when solutions of gum guiac, guiacol, and syringaldzine were applied directly to mycelium grown on these...

Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
Resistance to rhizomania is a basic requirement for cultivars’ approval for commercialization. The objectives of this research were to identify germplasm accessions that carry resistance genes to rhizomania and storage root rots. Twenty-one sugar beet (Beta vulgaris L.) germplasm from the USDA-ARS Kimberly sugar beet program and four check cultivars were screened for resistance to Beet necrotic yellow vein virus (BNYVV) during the 2011 growing season and during the 2011/2012 storage period for fungal growth in an indoor storage.  The rhizomania evaluation was conducted at the rhizomania nursery in the USDA-ARS North Farm in Kimberly, ID.  The crop was managed according to standard cultural practices and pest control.  The plots were rated twice (4 weeks...

Reducing sucrose loss in sugar beet storage with fungicides
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Neher, Oliver T.; Rearick, E.; Eujayl, Imad A.
Root rots in sugar beet storage can lead to multi-million dollar losses because of reduced sucrose recovery. Thus, studies were conducted to establish better chemical control options and a better understanding of the fungi involved in the rot complex. A water check and three fungicides (Mertect, Propulse, and Stadium) were investigated for their ability to control fungal rot on sugar beet roots held in long term storage during both the 2012 and 2013 storage seasons. At the end of September into October, roots were collected on 5 subsequent weeks, treated, and placed on top of a commercial indoor storage pile until early February. Differences (P &lt;0.0001 to 0.0150) between spray treatments were evident with both Propulse and Stadium reducing fungal growth...

Moniliellomycetes and Malasseziomycetes, two new classes in Ustilaginomycotina
Provedor de dados: 16
Autores: Wang, Q.-M.; Theelen, B.; Groenewald, M.; Bai, F.-Y.; Boekhout, T.
Ustilaginomycotina (Basidiomycota, Fungi) has been reclassiﬁed recently based on multiple gene sequence analyses. However, the phylogenetic placement of two yeast-like genera Malassezia and Moniliella in the subphylum remains unclear. Phylogenetic analyses using different algorithms based on the sequences of six genes, including the small subunit (18S) ribosomal DNA (rDNA), the large subunit (26S) rDNA D1/D2 domains, the internal transcribed spacer regions (ITS 1 and 2) including 5.8S rDNA, the two subunits of RNA polymerase II (RPB1 and RPB2) and the translation elongation factor 1-α (EF1-α), were performed to address their phylogenetic positions. Our analyses indicated that Malassezia and Moniliella represented two deeply rooted lineages within...

Stripe smuts of grasses: one lineage or high levels of polyphyly?
Provedor de dados: 16
Autores: Savchenko, K.G.; Carris, L.M.; Castlebury, L.A.; Heluta, V.P.; Wasser, S.P.; Nevo, E.
Stripe smut of grasses, Ustilago striiformis s.l., is a complex of smut fungi widely distributed over temperate and subtropical regions. The disease results in the shredding and death of leaf tissue following the rupture of elongated sori. Nearly 100 different grass species in more than 30 genera are infected by stripe smut. During the last two centuries more than 30 smut taxa have been described from members of this complex. The present study attempts to clarify the taxonomy and phylogeny of stripe smuts on grasses by analysing both morphological and molecular data. More than 200 specimens from different continents and host plants were examined. DNA was extracted from teliospores of 23 specimens from different hosts collected in Europe, Asia, and North...

European species of Clavaria (Agaricales, Agaricomycetes) with dark basidiomata – a morphological and molecular study
Provedor de dados: 16
Autores: Kautmanová, I.; Tomšovský, M.; Dueñas, M.; Martín, M.P.
Clavaria species with dark basidiomata occurring in Europe were analysed using morphological and molecular methods. Morphological analyses revealed four groups containing seven Clavaria species with dark basidiomata. Phylogenetic analysis of the LSU nrDNA region confirmed the separate positions of all seven Clavaria species within the genus. All sequences were grouped in four well-supported clades, mostly corresponding to defined morphological species. The results of the molecular study are inconsistent with the infrageneric classification of Clavaria based on the presence or absence of clamps on the bases of basidia and two widely accepted subgenera. Clavaria and Holocoryne appear to be polyphyletic. A new approach in species delimitation is presented: 1)...

The phylogenetic position of Rhopalostroma as inferred from a polythetic approach
Provedor de dados: 16
Autores: Stadler, M.; Fournier, J.; Gardt, S.; Peršoh, D.
The xylariaceous genus Rhopalostroma comprises a small conglomerate of stromatic, angiospermassociated pyrenomycetes, which have so far exclusively been reported from the palaeotropics, above all from tropical Africa and South Asia. Morphological and chemotaxonomic studies had suggested their close relationship to the genera Daldinia and Hypoxylon. However, those results were mainly based on herbarium specimens, and no molecular phylogenetic data were available on Rhopalostroma. During a foray in Côte d’Ivoire, fresh material of R. angolense was collected, cultured and studied by microscopic methods and by secondary metabolite profiling using high performance liquid chromatography coupled with diode array and mass spectrometric detection. In addition, ITS...

Promotion of growth and control of damping-off (Rhizoctonia solani) of greenhouse tomatoes amended with vermicompost
Provedor de dados: 85
Autores: Rivera,MC; Wright,ER; López,MV; Garda,D; Barragué,MY.
The pathogen Rhizoctonia solani (teleomorph Tanatephorus cucumeris) can affect tomatoes germination and emergence and cause basal rot of seedlings. It is generally accepted that composts suppress plant diseases, improve soil nutrient availability and stimulate plant growth. However, no reports have been found on the simultaneous evaluation of vermicompost as plant growth promoter and suppressive to damping-off caused by R. solani on tomatoes. This research evaluated the suppressive effects of different concentrations of vermicompost against R. solani and the ability of vermicompost to promote tomato seedlings growth. The microbial composition of the substratum was explored. Thirty six microorganisms were isolated, 13 of which were antagonic to R.solani in...

MANAGEMENT OF PARTHENIUM WEED USING METABOLITES OF Alternaria japonica
Provedor de dados: 87
Autores: JAVAID,A.; MUBEEN,T; BASHIR,U; SHOAIB,A.
ABSTRACT Parthenium (Parthenium hysterophorus) is an alien invasive weed infesting many parts of the world including Pakistan. A number of herbicides have been recommended for control of this weed, but these herbicides have issues regarding human health and environmental safety. In the current study, the herbicidal potential of culture filtrates of a fungal species, namely Alternaria japonica, was evaluated against parthenium weed. The fungal species was grown in malt extract broth (MEB) and potato dextrose broth (PDB) for 15 days. Culture filtrates were obtained by passing the materials through muslin cloth followed by filtration through filter paper and then through Millipore filter paper. In laboratory bioassays, the effect of original (X) and diluted...

Diagnosis and evaluation of fungi presence in the air of two different ventilation sytems for broiler houses
Provedor de dados: 89
Autores: Gigli,ACS; Baracho,MS; Nääs,IA; Silva,RA; Zago,R; Dall'Anese,FP.
Intensive broiler production in tropical climates requires adequate air circulation to control heat stress. Excess of air speed may lead to dust production and reduction of air quality and, consequently, production parameters. Brazilian regulations prohibit the presence of pathogens that may deteriorate air quality, and the presence of fungi in the air inside the poultry houses is limited to 750CFU/m³. The aim of this study was to evaluate the presence of fungi in two distinct types of broiler houses. The research compared two types of air ventilation: conventional (G1) and positive tunnel ventilation (G2). The fungi were collected using a dust sampling pump, with the air flow calibrated to 1.5 L/min. The filter impregnated with dust was submitted to...

Iron Uptake by Fungi Isolated from Arcelor Mittal -Annaba- in the Northeast of Algeria
Provedor de dados: 89
Autores: Bourzama,G; Ouled-Haddar,H; Marrouche,M; Aliouat,A.
ABSTRACT The Metal pollution is one of the major risks in the world nowadays. Iron is an essential metal for growth and proliferation of a vast majority of organisms, but it can be toxic to human health and other living beings in the environment at high concentrations due to its increased industrial activity. Fungi have a remarkable capacity to uptake and detoxify iron metal using different mechanisms such as bioaccumulation. Thus, the aim of this work is to study the ability of iron uptake by the fungal strains isolated from Arcelor Mittal -Annaba- in Algeria. Three strains were screened at high concentration of iron (1 g/l) and their capacity to uptake iron has been studied on Czapek Yeast Agar medium. The amounts of uptaken iron ions were estimated in...

Provedor de dados: 90
Autores: Moreira,Geisianny Augusta Monteiro; Vale,Helson Mario Martins do.
ABSTRACT Soils of the Quadrilátero Ferrífero are rich in mineral resources, especially gold and iron. Soil management and mining activities greatly impact soil biology. However, studies addressed to the diversity of microorganisms and their ecological role in the recovery of these areas are scarce. This study aimed to assess the yeast occurrence in soils with natural vegetation (Atlantic Forest, neotropical savanna, and iron outcrop) and areas with anthropogenic modifications (Eucalyptus stand and rehabilitated area) in the Quadrilátero Ferrífero region. We isolated and identified a total of 68 yeast. Partial sequencing of the 26S ribosomal gene revealed the presence of six genera: Saitozyma, Pseudozyma, Meyerozyma, Debaryomyces, Lipomyces, and...

Autores: Brandão,Fernando J. B.; Biaggioni,Marco A. M.; Sperotto,Felipe C. S.; Fujita,Erika; Santos,Paula L.; Silva,Magnun A. P. da.
ABSTRACT Ozone is used in many countries for the treatment of effluents, becoming a viable alternative in sanitation of coffee wastewater. However, the strong ozone oxidation, responsible for its germicidal effect, can also compromise grain and beverage quality. The objective of this study was to evaluate the quality of Arabica coffee in different periods of treatment with ozonated water and its effect after drying. Coffee fruits were subjected to ozonation at regular intervals of 0, 5, 10, 20, and 30 min, with continuous stirring promoted by a recirculating water system at constant rate of 1 ppm of solubilized ozone. The design was completely randomized with five treatments and four replicates. After obtaining the data, the analysis of variance was...

Autores: LOPES,ROGÉRIO BIAGGIONI; TAMAI,MARCO ANTONIO; ALVES,SÉRGIO BATISTA; SILVEIRA NETO,SINVAL; SALVO,SÉRGIO DE.
Thrips are reported as important pests on table grapes in United States and several countries of Europe. Damage caused by thrips, particulary Frankliniella occidentalis, was observed on niagara table grape crop in Limeira-SP, Brazil. During the blooming period, high thrips densities were observed feeding on pollen and small berries. The symptoms left were more visible after the development of the berries and were characterized by dark scars and suberized surface on berries, sometimes causing the berry to crack, and the seed to prolapse. The effect of insecticides thiacloprid or methiocarb, associated or not with the entomopathogenic fungus Metarhizium anisopliae were evaluated during the blooming period. For evaluation of thrips damage on fruits, the...

Abstract  Black fly is a pest of Asian origin that causes direct and indirect damages to citrus, damaging the development and production of plants. For the development of efficient management strategies of the pest, the integration of control methods is necessary, and biological control is the most appropriate. Among the agents that can be used, entomopathogenic fungi are considered one of the most important and wide-ranging use. This work investigated the occurrence of Purpureocillium lilacinum (Thom.) Luangsa-ard et al. (= Paecilomyces lilacinus), attackingnymphs of citrus black fly, Aleurocanthus woglumi Ashby (Hemiptera: Aleyrodidae). The fungus was isolated from infected Black fly nymphs, present on Citrus spp leaves in the municipality of Morros,...

Curvularia pallescens Boedijn (Hyphomycetes) is redescribed with the aid of a scanning electron microscope, and the optimal cultural conditions for growing this fungus are discussed. Cytological analysis and nuclear condition, observed through the HCl-Giemsa technique, showed vegetative and reproductive structures (hypha and conidia) formed by uni, bi, tri, and multinucleated segments. Cultures of C. pallescens in Complete medium and in Potato dextrose agar varied on growth, on aspects of the border of the colonies and also on medium pigmentation. The Complete medium and the temperature between 25-28°C were the most indicated for growth of C. pallescens.

Autores: Pattamawan Maneesuwan; Pisan Sirithorn.
The five concentrations of cell suspension of Bacillus licheniformis BFP011 each applied to reduce the disease symptom caused by Colletotrichum capsici using the detached fruit technique with Completely Randomized Design (CRD). The statistical analysis indicated that inoculation of cell suspension prior to inoculation of C. capsici gave more disease severity reduction than inoculation of C. capsici prior to inoculation of cell suspension. The optimal concentration that reduced disease severity; without adverse effect was at 1x104-1x105 cfu/ml prior to inoculation of C. capsici for 24 hours as disease severity was reduced by 35.8% and 34.8%, respectively. The cell suspension at the concentrations between 1x106 to 1x108 cfu/ml induced fruit rot to 10-50%....

Provedor de dados: 106
Autores: Pattamawan Maneesuwan; Pisan Sirithorn.
Capability of 11 isolates of Bacillus spp. previously reported as antagonistic against some plant pathogens was tested. This is to inhibit the growth of four isolates of Colletotrichum capsici isolated from stalk, leaf, fruit and 158 ci/KU, by employing Completely Randomized Design (CRD) consisting of 11 treatments with 4 replications. The results showed that B. licheniformis BFP011 exhibited the most promising inhibition. Similarly, the evaporated crude extract produced by B. licheniformis BFP011 was able to inhibit greatly growth of C. capsici. When mycelium and spores of C. capsici were immersed in cell suspension at 1x108 cfu/ml and the evaporated crude extract at 1,000 mg/ml of B. licheniformis BFP011 for 24 hours. It is obvious that abnormal hypha...

Autores: Tavares,Eder T.; Tigano,Myrian S.; Mello,Sueli C. M.; Martins,Irene; Cordeiro,Celia M. T.
Forty-nine Brazilian Dicyma pulvinata isolates were examined by morphological traits and RFLP, RAPD and AFLP analyses. This fungus is a mycoparasite of Microcyclus ulei, the causal agent of the most devastating rubber (Hevea brasiliensis) disease, known as "South American Leaf Blight" (SALB). These isolates were compared with an Indian isolate from Cercosporidium sp., and a French isolate from Cladosporium fulvum. They were also compared with Dicyma ampullifera from Papua New Guinea. The morphological parameters analyzed confirmed the identification of the Brazilian isolates. The graphic representations of the distance matrices of each molecular marker showed similar results. Dicyma pulvinata isolates from M. ulei were closely related, whereas the...

Autores: SANTANA,Marcos Diones Ferreira; COUCEIRO,Douglas de Moraes; COUCEIRO,Sheyla Regina Marques.
ABSTRACT Three species of the Ascomycetes genus Camillea were recorded in a fragment of Amazon rainforest in the region of Santarém, Pará state, Brazil. The occurrence of C. leprieurii, C. cyclops and C. bilabiata expand the range of distribution of these species in the state. Camillea leprieurii has previous records in the regions of Marabá, Oriximiná, Itaituba and Novo Progresso, while C. cyclops had been recorded in the west of the state. This is the first record of C. bilabiata for Pará. We provide a morphological description of the specimens and an identification key for Camillea species found in Pará.

Biological collections in natural history museums serve important purposes to the scientific community and the general public, however, their value and utility might be diminished by biodeterioration. We studied a biological collection that represents more than sixty years of avifauna sampling of Colombia, the country with the highest bird diversity. An initial inspection of the collection showed that the general appearance of some specimens was compromised by mold-like growth on their surfaces. We aimed at (i) identifying the taxonomic affiliation of these fungi, (ii) evaluating their cellulolytic activity, and (iii) probing chemical agents that could be utilized to control their growth. The most common fungi genera were Aspergillus, Penicillium,...

Abiotic effects on the cover and richness of corticolous lichens on Araucaria angustifolia trunks
Provedor de dados: 39
Autores: Nunes,Lucas; Burle,Giulia; Gumboski,Emerson Luiz; Dechoum,Michele.
ABSTRACT Lichens play a key role in natural ecosystems, as they can function as primary producers, recycle minerals and fix nitrogen. Despite their environmental importance, little is known about lichen ecology in Brazil, and especially about how abiotic factors may influence their spatial distribution. In this study, we aimed to verify how the cover and richness of corticolous lichens on Araucaria angustifolia trunks vary between two different habitats (Forest and Grassland). The photoquadrat sampling method was applied to A. angustifolia trunks. The Coral Point Count software with Excel extensions (CPCe) was used to analyze photographs for lichen cover and richness. Additionally, a redundancy analysis was conducted to estimate how five abiotic and two...

Aflatoxins are carcinogens produced by Aspergillus flavus, A. parasiticus and A. nomius. In the present study, peanut samples were collected at different phenological stages of the plant during the 2007/2008 and 2008/2009 seasons and from stored peanuts harvested in 2007/2008. The mycoflora and aflatoxins in the peanuts were evaluated. The results showed the presence of Fusarium spp., Macrophomina spp., Trichoderma spp., Aspergillus spp. and Cladosporium spp. during the period of peanut maturation (39.8, 17.9, 8.2, 2.7 and 1.7%, respectively) and storage (49.8, 27.8, 12.5, 8.8 and 1.0%, respectively). However, aflatoxins were not detected in the samples. Of the 25 Aspergillus spp. isolates, 24 (96%) were producers of aflatoxin B1 (96%), 10 (40%) of...

Provedor de dados: 3
Autores: Camerini, Felipe Vieira; Chanin, Carlo do Amaral; Borba, Carina Molins; Costa, Jorge Alberto Vieira; Burkert, Carlos André Veiga; Burkert, Janaína Fernandes de Medeiros.
Biosurfactant are surface active compounds with emulsifying capacity and are produced by microorganisms, and they may be affected by factors related to microbial cultivation, such as pH, salinity, incubation time, carbon and nitrogen sources. The aim of this work was to study the influence of the culture conditions on the production of biosurfactants by Phialemonium sp using agroindustrial wastes. The processing parameters of temperature, humidity and pH produced the most significant effects on the production of biosurfactant and emulsifying activity. The maximum concentration of biosurfactant obtained in this study was equivalent to a surface tension reduction of 8.5 mg L-1 surfactin commercial solution using wheat bran, pH of 4.5, and 0.5% of soybean oil...

Secondary metabolites from marine microorganisms
Provedor de dados: 42
Autores: KELECOM,ALPHONSE.
After 40 years of intensive research, chemistry of marine natural products has become a mature field. Since 1995, there are signals of decreased interest in the search of new metabolites from traditional sources such as macroalgae and octocorals, and the number of annual reports on marine sponges stabilized. On the contrary, metabolites from microorganisms is a rapidly growing field, due, at least in part, to the suspicion that a number of metabolites obtained from algae and invertebrates may be produced by associated microorganisms. Studies are concerned with bacteria and fungi, isolated from seawater, sediments, algae, fish and mainly from marine invertebrates such as sponges, mollusks, tunicates, coelenterates and crustaceans. Although it is still to...

Abstract  Grape pomace from Vitis labrusca is an important sub-product of the “American table wine” industry. It is recalcitrant to degradation, and its accumulation is a serious problem with negative environmental impacts. We analyzed the ability of five white-rot fungi to transform this residue in-vitro. Mass loss and phenol removal in grape pomace treated with each fungus were compared after 30-day solid-state fermentation. Since Peniophora albobadia isolate LPSC 285 was the fungus that showed the highest degradative ability and the lowest free phenol levels in the residue transformed, we selected this fungus to monitor its effect on this residue after 30, 60, and 90 days of incubation. We analyzed mass loss of the residue caused by the fungus activity...

Cutaneous mycobiota of boid snakes kept in captivity
Provedor de dados: 45
Autores: Freire,B.C.; Garcia,V.C.; Quadrini,A.E.; Bentubo,H.D.L.
ABSTRACT Boids are large, constrictor snakes that feed mostly on mammals, reptiles, and birds. These animals are commonly raised as pets, and their improper handling can favor the emergence of fungal infections, which can lead to dermatological diseases that are undiagnosed in nature. Here, we isolate and identify the filamentous fungi that compose the mycobiota of the scales of boid snakes kept in captivity at the Biological Museum of the Butantan Institute. Thirty individuals of four species were evaluated: four Eunectes murinus, twelve Boa constrictor constrictor, seven Corallus hortulanus, and seven Epicrates crassus. Microbiological samples were collected by rubbing small square carpets on the snake scales. We isolated five genera of fungi:...

Autores: Cinto,Isabel E.; Dokmetzian,Diana A.; Ranalli,María E.
The aim of this study was to delimit two Iodophanus species: I. carneus and I. testaceus , based on morphological characteristics and electrophoretic patterns of their intracellular isozymes. Twenty monosporic strains were used, including five belonging to I. granulipolaris as a control. Fourteen isozyme systems were tested, and the five having the best resolution selected: aspartate aminotransferase, esterases, alkaline phosphatase, glutamate dehydrogenase, and superoxide dismutase. These analyses confirmed the similarity between I. carneus and I. testaceus , since they both produced the same band patterns, which were in turn different from the band pattern of I. granulipolaris. So, as we couldn´t find any character wich permit us to classify the isolated...

Autores: Miranda,Vitor Fernandes Oliveira de; Martins,Vanderlei Geraldo; Furlan,Antonio; Bacci Jr.,Maurício.
The nuclear ribosomal DNA internal transcribed spacers (ITS1 and ITS2) from leaves of Drosera (Droseraceae) were amplified using "universal" primers. The analysis of the products demonstrated most samples were a molecular mixture as a result of unsuccessful and non-specific amplifications. Among the obtained sequences, two were from Basidiomycota fungi. Homologous sequences of Basidiomycota were obtained from GenBank database and added to a data set with sequences from Drosera leaves. Parsimony analysis demonstrated that one sequence was amplified from an Ustilaginomycetes fungus, and another from a Heterobasidiomycetes. Possibly these fungi were associated to leaves of Drosera, and not because of samples contamination. In order to provide optimization and...

Autores: Sing,Ngieng Ngui; Zulkharnain,Azham; Roslan,Hairul Azman; Assim,Zani; Husaini,Ahmad.
Four fungal isolates, SD12, SD14, SD19 and SD20 isolated from the aged sawdust grew on agar plates supplemented with PCP up to a concentration of 100 mg L-1. At high PCP concentration, isolate SD12 showed the highest radial growth rate of 10 mm day-1, followed by SD14 and SD19 both with 4.5 mm day-1 and SD20 with 4.2 mm day-1. Ultrastructural study on the effect of PCP on the PCP tolerant fungi using scanning electron microscope showed that high concentration of PCP caused the collapse of both fungal hyphae and spores. Among the four PCP tolerant fungi examined, isolate SD12 showed the least structural damage at high PCP concentration of 100 mg L-1. This fungal isolate was further characterized and identified as Cunninghamella sp. UMAS SD12. Preliminary...

This work had as objectives the study of the physical and mechanical characteristics of maize kernels in relation to the contamination by Fusarium sp and by zearalenone in twenty landraces of maize from the southern region of Brazil. From the analyzed samples, 60 % has been considered to have a hard endosperm type and 40 % an intermediary one. A correlation between the physical and mechanical variables was observed as an indication that the higher is the proportion of hard endosperm, more dense will be the kernel and more force for its rupture will be necessary. The level of contamination by Fusarium sp was between 5.5 and 24.75% among the analyzed grains, correlating positively with the flotation index, indicating that the landraces of maize with a softer...

Interference of a commercial catalase preparation in laccase and peroxidase activities
Provedor de dados: 52
Autores: Ballaminut,Nara; Yamanaka,Renata; Machado,Katia Maria Gomes.
The influence of commercial catalase preparations (fungal and bovine origin) on laccase and peroxidase activity assays was evaluated using enzymatic extracts obtained from several basidiomycetes grown under different culture conditions. No hydrogen peroxide was detected in the extracts. Inhibition of laccase activity by 40 to 80% was related to the catalase source. In addition, oxidation of the substrate (ABTS) by fungal catalase in the absence of the enzymatic extract from basidiomycetes was observed. The results demonstrated the need for the evaluation of interference of the commercial catalase preparation when its use was required in the reaction mixture.

Provedor de dados: 52
Autores: Aguiar,Mario Mamede; Ferreira,Luiz Fernando Romanholo; Monteiro,Regina Teresa Rosim.
In this present work, three strains of Pleurotus and Trichoderma reesei were cultivated in media with pre-treated bagasse and vinasse. Cellulolytic and lignolytic activities and biomass production were analyzed. The treatment of the bagasse with 2% H2O2 + 1.5% NaOH + autoclave resulted in a greater fiber breakage increasing the cellulose level up to 1.2 times and decreasing 8.5 times the hemicellulose content. This treatment also resulted in a high lignolytic activity for all cultures utilized. T. reesei produced laccase, peroxidase and manganese-peroxidase in all the treatments, having its manganese-peroxidase activity raging from 1.9 to 4.8 times higher than the basidiomycetes.

Autores: Sene,Luciane; Converti,Attilio; Secchi,Geslaine Aparecida Ribeiro; Simão,Rita de Cássia Garcia.
The world practice of using agrochemicals for long periods, in an indiscriminated and abusive way, has been a concern of the authorities involved in public health and sustainability of the natural resources, as a consequence of environmental contamination. Agrochemicals refer to a broad range of insecticides, fungicides and herbicides, and among them stands out atrazine, a herbicide intensively used in sugarcane, corn and sorghum cultures, among others. Researches have demonstrated that atrazine has toxic effects in algae, aquatic plants, aquatic insects, fishes and mammals. Due to the toxicity and persistence of atrazine in the environment, the search of microbial strains capable of degrading it is fundamental to the development of bioremediation...

Abstract Clean, fresh air is the most important requirement for good indoor air quality (IAQ) in all buildings, but it is especially important with regard to the environments within hospitals and other healthcare facilities. The literature indicates that buildings with heating, ventilating and air conditioning (HVAC) systems may have an increased risk of sick building syndrome (SBS) and building-related illness (BRI) if they are not well maintained. Microorganisms are brought into hospitals by people, air currents, water, construction materials and equipment. The main objective of this study was to assess the degree of fungal and bacterial contamination in the University Clinical Centre in Banja Luka, which is directly connected to the HVAC system....

Autores: ARAÚJO,Jackson Victor de.
Laboratory experiments were performed in order to investigate the capacity of isolates from the predacious fungi Arthrobotrys musiformis (isolate 3), A. conoides (isolate A) and A. robusta (isolates B and E) to trap and kill infective Cooperia punctata larvae. Two groups were formed for each isolate: group 1, fungi and infective larvae and group 2, infective larvae (control). There were statistical differences (p&lt;0.05) between the predacious activity of one isolate of A. robusta (isolate E) when compared with the other isolates of Arthrobotrys spp (isolates A, B and 3). No statistical difference (p&gt;0.05) was found between the isolate E and the control. This indicates that there can be an existing variability within a fungus species or genus...

Comparative virulence of Scedosporium species in animal models
Provedor de dados: 55
Autores: Nweze,EI; Okafor,JI.
Scedosporium species are an emerging opportunist group of fungi that have been found to cause infections in both immunocompetent and non-immunocompetent individuals. The infections are not regularly distributed among different countries of the world either because of improper identification or other geographical reasons. Strange as it may, disseminated systemic infections have only been reported in some specific countries. We used a mouse model of disseminated infection to assess if strains from Nigeria were virulent and compared it to a few other strains from other countries. S. apiospermum isolated from Nigeria were clearly less virulent than those obtained elsewhere. This may be the reason why this group of fungi has not been associated with specific...

Isolation of fungi from dung of wild herbivores for application in bioethanol production
Provedor de dados: 58
Autores: Makhuvele,Rhulani; Ncube,Ignatious; Jansen van Rensburg,Elbert Lukas; La Grange,Daniël Coenrad.
ABSTRACT Producing biofuels such as ethanol from non-food plant material has the potential to meet transportation fuel requirements in many African countries without impacting directly on food security. The current shortcomings in biomass processing are inefficient fermentation of plant sugars, such as xylose, especially at high temperatures, lack of fermenting microbes that are able to resist inhibitors associated with pre-treated plant material and lack of effective lignocellulolytic enzymes for complete hydrolysis of plant polysaccharides. Due to the presence of residual partially degraded lignocellulose in the gut, the dung of herbivores can be considered as a natural source of pre-treated lignocellulose. A total of 101 fungi were isolated (36 yeast...

Litopenaeus vannamei, which is the most common shrimp species cultivated in the northeast of Brazil, is very susceptible to microbial diseases, and this consequently affects productivity. There are reports of bacteria, viruses and protozoa in these shrimp, but not fungi. This study aims to isolate and identify fungi present in shrimp Litopenaeus vannamei, and in their nursery waters, at two breeding farms in Brazil. The pathogenic potential of the isolates was assessed through the qualitative detection of proteases and aflatoxin B production. The 146 isolated fungi comprised 46 species. Aspergillus, Penicillium and Furarium were the three most relevant genera and Aspergillus flavus was the predominant species with a total of 33 isolates. Most of the...

Autores: Vieira,Gabriela A.L.; Magrini,Mariana Juventina; Bonugli-Santos,Rafaella C.; Rodrigues,Marili V.N.; Sette,Lara D.
ABSTRACT Pyrene and benzo[a]pyrene (BaP) are high molecular weight polycyclic aromatic hydrocarbons (PAHs) recalcitrant to microbial attack. Although studies related to the microbial degradation of PAHs have been carried out in the last decades, little is known about degradation of these environmental pollutants by fungi from marine origin. Therefore, this study aimed to select one PAHs degrader among three marine-derived basidiomycete fungi and to study its pyrene detoxification/degradation. Marasmiellus sp. CBMAI 1062 showed higher levels of pyrene and BaP degradation and was subjected to studies related to pyrene degradation optimization using experimental design, acute toxicity, organic carbon removal (TOC), and metabolite evaluation.

Autores: Burgdorf,R.J.; Laing,M.D.; Morris,C.D.; Jamal-Ally,S.F.
Extraneous DNA interferes with PCR studies of endophytic fungi. A procedure was developed with which to evaluate the removal of extraneous DNA. Wheat (Triticum aestivum) leaves were sprayed with Saccharomyces cerevisiae and then subjected to physical and chemical surface treatments. The fungal ITS1 products were amplified from whole tissue DNA extractions. ANOVA was performed on the DNA bands representing S. cerevisiae on the agarose gel. Band profile comparisons using permutational multivariate ANOVA (PERMANOVA) and non-metric multidimensional scaling (NMDS) were performed on DGGE gel data, and band numbers were compared between treatments. Leaf surfaces were viewed under variable pressure scanning electron microscopy (VPSEM). Yeast band analysis of the...

Autores: Pinho,Beatriz Helena; Furlong,Eliana Badiale.
The quality of pre-cooked pizza dough was investigated by assessing the occurrence of molds, yeasts and mycotoxins. Random sampling of commercial pre-cooked pizza cakes was done in different stores in the cities of Rio Grande and Pelotas, RS, between 1996 and 1997. The products were analysed on the sampling day and after storage at room (22-30ºC) or refrigerated temperature (7ºC) following the shelf life stated by the manufacturer (25,30 and 45 days). The results showed that mold and yeast contamination was frequently above the maximum limits (10³CFU/g-1) established by Brazilian guide lines, even in samples kept at refrigerated temperatures up to the end of shelf life. Although no mycotoxin contamination was detected, a strain of the Penicillium genus,...

Autores: Thomas,Manuel; Samuel K,Abraham; Kurian,Punnen.
The past few decades have witnessed an overwhelming increase in the incidence of fungal infections, particularly in immunocompromised individuals. Consequently, zoonotic diseases, especially through rodents constitute a prominent group among the emerging diseases. Rodents are commensal to man and related health risks are common. Water rats (Rattus norvegicus) are typical to Vembanadu-Kol wetland agroecosystems, where they can act as a good carrier nexus for pathogens. The present study evaluates the carrier status of water rats with respect to fungal pathogens. A total of fifty two fungi covering eighteen families were isolated. Among the isolates, eight were dermaptophytes and Chrysosporium sp. (89.18%) was the frequent isolate. The source-wise analyses...

Provedor de dados: 58
Autores: Clemente,Andrea R.; Anazawa,Tania A.; Durrant,Lucia R.
Thirteen deuteromycete ligninolytic fungal strains were grown in media containing polycyclic aromatic hydrocarbons (PAHs), for 6 and 10 days. The PAHs were added directly with the inocula or on the third day of cultivation. A selection of the best strains was carried out based on the levels of degradation of the PAHs and also on the ligninolytic activities produced by the fungi. The selected strains were cultivated for 3, 6, 9, 12 and 15 days in the PAHs-containing media. Degradation of PAHs, as measured by reversed-phase HPLC on a C18 column, varied with each strain as did the ligninolytic enzymes present in the culture supernatants. Highest degradation of naphthalene (69%) was produced by the strain 984, having Mn-peroxidase activity, followed by strain...

Abstract Basidiomycetes have several biotechnological and industrial applications such as enzyme production, bioremediation, pharmaceutical and functional food production. Due to climatic features, the preservation of several basidiomycetes is threatened, and to guarantee the preservation of this genetic resource, the development of long-term preservation techniques is necessary once there is no universal protocol for the cryopreservation of basidiomycetes. Cryopreservation is a technique in which microorganisms are submitted to ultralow temperatures. Therefore, this study aimed to collect information on the main conditions for long-term cryopreservation of basidiomycetes in the last 20 years.

Autores: Soncini-Júnior,Giancarlo; Franchetti,Sandra Mara Martins; Marconato,José Carlos.
A microscopical study was undertaken to analyze the eventual fungi adhesion over a polyester imide surface in enameled copper wires. Scanning electron microscopy allowed to observe in these adhered biofilms, a high amount of pigments, hyphae and its enzymatic arsenal probably acting in the surface of the polymer. Due to the highly aromatic nature of this polyester and the residual phenol derivates still present in the reticulated polymer, an antifungal activity could be expected, but no significant changes were noted in fungal growing and in the adhesion process. Additionally, the wires showed completely failure in all insulation properties. The studies aimed to understand and evaluate the great fungi potential that could be explored in biodeterioration...

Autores: del Palacio,Agustina; Bettucci,Lina; Pan,Dinorah.
Abstract Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage is vulnerable to contamination by spoilage molds and mycotoxins because ensilage materials are excellent substrates for fungal growth. The aim of the study was to identify the mycobiota composition and occurrence of aflatoxins and DON from wheat silage. A total of 220 samples of wheat were collected from four farms in the southwest region of Uruguay were silage practices are developed. The main fungi...

Microsporum canis is an important agent of dermatophitosis in human and animal. The aim of the current study was to assess the efficacy of ozonized oil over Microsporum canis in rabbits. Eighteen male New Zealand white rabbits, weight ranging from 2 to 3.2 kg were depilated in the cranial dorso-lateral and right caudal, and cranial and left caudal regions. The regions were inoculated with Microsporum canis, excepting the right caudal region, and were denominated TM, O, OM and M, respectively. After seven days, the treatment of lesions in TM...

Screening of different fungi for decolorization of molasses
Provedor de dados: 58
Autores: Seyis,Isil; Subasioglu,Tugba.
The decolorization of molasses by 17 different fungi in 2 media was studied. Trichoderma viride showed the highest decolorization yield (53.5%) when cultivated at 30°C for 7 days in Medium 1 which contained the molasses which was diluted to 40 g/L in distilled water. The other Trichoderma species and Penicillium sp. also gave similar results of 40-45%. Decolorization yield was increased by adding peptone and yeast extract to the production medium except Penicillium sp. Growth rate was not related to decolorization yet pH value was. When the pH decreased below 5.0 after the incubation, the decolorization yield increased. Although reducing sugar in culture broth decreased with decreasing color intensity, there was no connection between protein utilization...

Genetic variability of brazilian Alternaria spp. isolates as revealed by RAPD analysis
Provedor de dados: 58
Autores: Tigano,Myrian Silvana; Aljanabi,Salah; Mello,Sueli Corrêa Marques de.
The genetic variability of 22 isolates of the fungi Alternaria alternata and A. cassiae, obtained from Senna obtusifolia, was studied by RAPD analysis. A total of 491 scorable bands were produced with the use of 28 primers. Cluster analysis based on similarities computed from RAPD markers showed two distinct genetic groups of isolates related to both species. RAPD analysis proved to be an efficient method for detecting genetic variability of A. cassiae and A. alternata isolates occurring in S. obtusifolia, and also for distinguishing Alternaria species.

Provedor de dados: 60
Autores: Kujbida,Paula; Maia,Patrícia Penido; Araújo,Ariadne Naama de; Mendes,Leonardo Daniel; Oliveira,Mariana Lepri de; Silva-Rocha,Walicyranison Plinio; Brito,George Queiroz de; Chaves,Guilherme Maranhão; Martins,Isarita.
In the present study, the occurrence of fungi and aflatoxins (AFs) in peanut and cashew nut samples was investigated. Mycological analysis revealed the presence of fungi in 58.8% of samples, and assessment of AFs by chromatographic methods revealed that 52.9% were contaminated by AFs. AFB1 was the principal component in all AF-contaminated samples, with a mean level of 14.0, and 1.08 µg/kg in peanut and cashew nut, respectively. Eleven samples (32.4%) exceeded the total AF maximum level (4 μg/kg) and 8 samples (23.5%) exceeded the AFB1 (2 μg/kg) established by the European Commission. Our findings suggest that the incidence of AFs emphasizes the need for regular monitoring and a more stringent food safety system to control AFs at the lowest possible levels...

Effect of the geographical origin, culture media, and pH on the growth dynamic of the edible ectomycohrrizal mushroom Suillus luteus
Provedor de dados: 118
Autores: Santelices,Rómulo; Espinoza,Sergio; Brunel,Nidia; Palfner,Gotz.
Suillus luteus is the most important wild edible ectomycorrhizal mushroom harvested and exported in Chile. This introduced species forms mycorrhizal symbiosis with Pinus radiata, the most important exotic forest tree. To obtain optimized protocols for the controlled infection of P. radiata trees with this species, it is important to determine the appropriate culture conditions. Therefore, we studied the effect of the geographical origin (three localities from the Maule Region of Chile), culture media (Modified Melin and Norkrans (MMN) and Malt Extract Agar (MEA) 2%), and pH (5.0, 5.8, and 6.5) on the in vitro growth dynamics of S. luteus over 37 days. The results showed significant differences in the growth rate and colony diameter as a consequence of its...

Provedor de dados: 64
Autores: Chalfoun,Sára Maria; Pereira,Marcelo Cláudio; Resende,Mario Lúcio V.; Angélico,Caroline Lima; Silva,Rozane Aparecida da.
The effect of ten powdered spice plants was evaluated at the concentration of 1, 2, 3 and 4% to observe the mycelial growth and sporulation of Aspergillus niger and Eurotium repens. The spices were added to the culture media PDA and CYA20S. Clove completely inhibited the mycelial growth of the tested fungi. The other spices: cinnamon, garlic, thyme, mint, anis, oregano and onion were, in a decreasing order, promising antifungals. Bay leaf and basil did not show a pronounced fungistatic effect. The antitoxigenic potential of the spices was tested against one aflatoxin-producing strain of AspergiIIus flavus. The spices were tested at the same concentrations previously mentioned and were added to the culture medium YES, appropriate for the production of those...
