Population genetic status of the Western Indian Ocean:  what do we know?
Provedor de dados: 20
Autores: Sampayo, E.M.; Ridgway, T.
Population genetics offers a useful technique for studying the population structure of marine organisms and has relevance to both systematics and the conservation of biodiversity. The Western Indian Ocean (WIO) is faced with increasing evidence of degradation and effective management initiatives are needed to curtail the environmental decline. The management of the WIO region can therefore benefit from the information that population genetics can provide. Extensive literature searches revealed only 31 genetic references for the WIO region. From a biogeographic point of view, the WIO shows little genetic exchange with the rest of the Indo- Pacific, but from a regional perspective, the limited information that exists points towards widespread genetic...

Autores: Mignani,Luciene; Barbieri,Edison; Marques,Helcio Luis de Almeida; Oliveira,Ana Julia Fernandes Cardoso de.
The objective of this work was to evaluate the total and thermotolerant coliform densities in the oyster culture water of Cananeia, SP, Brazil, correlating these densities with environmental variables and tidal variations. Superficial water samples were collected in two tide conditions (spring and neap) from three areas of Cananéia municipality (Mandira, Itapitangui and Cooperostra). The three studied areas showed good conditions for the culture regarding coliform densities. The two tidal conditions differed significantly as to total coliform concentration; however, the same procedure was not performed for thermotolerant coliforms. No correlation was observed between water temperature, pH, and concentrations of total and thermotolerant coliforms. Coliform...

ABSTRACT Brazil is the largest exporter of chicken meat and poultry farming is one of the most important productive segments, despite major losses due to the bacterium Escherichia coli, which is also a zoonotic microorganism. The objetive of this study was to isolate E. coli and to evaluate its transmissibility potential from the field to chicken meat using the Pulsed Field Gel Electrophoresis (PFGE) technique. Environmental samples (poultry litter, soil and water) were collected from broiler farms located in the South of Brazil where the majority of the Brazilian poultry production occurs. In addition, chicken meat (gizzard, heart, drumette and tulip) samples were collected from local supermarkets. As results, 47.36% of the samples were positives for E....

New record of Pterotaenia fasciata (Wiedemann) (Diptera, Ulidiidae) in Brazil, a probably mechanical vector of enteric bacteria
Provedor de dados: 92
Autores: Barnabe,Anderson Sena; Laporta,Gabriel Zorello; Laporta,Marcia Zorello; Lamas,Carlos José Einicker.
Pterotaenia fasciata is commonly recorded in rural areas in Argentina, but during a Diptera survey study developed in a reservoir which retains storm water from polluted canals in an urban area of Taboão da Serra municipality, SP, Brazil, we could capture P. fasciata adults. Enteric bacteria Escherichia coli T. Escherich, 1885 and Proteus sp. were isolated from P. fasciata collected in traps inside the reservoir and around it. Fecal coliforms and E. coli were found in the water of the reservoir. These records suggest that a high abundance of this species at urban areas with inadequate sewage canals should reveal these muscoid dipterans as mechanical vectors of enteric bacteria.

ABSTRACT With this study we aimed to evaluate and compare physicochemical and microbiological characteristics of frozen and chilled chicken meat. Only the prime cuts (breast, thighs, and drumsticks) were considered for the analysis of chemical composition, pH, color, water-holding capacity (WHC), thawing-cooking loss (TCL), and shear force (SF). For microbiological analysis, mesophilic bacteria, thermotolerant coliforms, and Salmonella spp. were considered. The frozen and chilled chicken meat showed no PSE (pale, soft, and exudative) or DFD (dark, firm, and dry) type of anomalies. The chromaticity showed higher redness in the breast (a* = 0.23) and yellowness in the thigh (b* = 5.64) for the frozen meat. The chilled meat showed better values for...

Arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) are able to provide key ecosystem services, protecting plants against biotic and abiotic stresses. Here, we hypothesized that a combination of AMF (Rhizophagus clarus) and PGPR (Bacillus sp.) could enhance 33P uptake in maize plants under soil water stress. A microcosm experiment using mesh exclusion and a radiolabeled phosphorus tracer (33P) was installed using three types of inoculation: i) only AMF, ii) only PGPR, and iii) a consortium of AMF and PGPR, alongside a control treatment without inoculation. For all treatments, a gradient of three water-holding capacities (WHC) was considered i) 30% (severe drought), ii) 50% (moderate drought), and iii) 80% (optimal condition,...

Abstract: The development of dwarf wheat cultivars combined with high levels of agrochemical inputs during the green revolution resulted in high yielding cropping systems. However, changes in wheat cultivars were made without considering impacts on plant and soil microbe interactions. We studied the effect of these changes on root traits and on the assembly of rhizosphere bacterial communities by comparing eight wheat cultivars ranging from tall to semi-dwarf plants grown under field conditions. Wheat breeding influenced root diameter and specific root length (SRL). Rhizosphere bacterial communities from tall cultivars were distinct from those associated with semi-dwarf cultivars, with higher differential abundance of Actinobacteria, Bacteroidetes and...

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: Ribas,Maria Magdalena Ferreira; Chinalia,Fabio Alexandre; Pozzi,Eloisa; Foresti,Eugenio.
The aim of this work was to investigate the anaerobic biomass formation capable of treating vinasse from the production of sugar cane alcohol, which was evolved within an anaerobic sequencing batch biofilm reactor (ASBBR) as immobilized biomass on cubes of polyurethane foam at the temperature of 55ºC. The reactor was inoculated with mesophilic granular sludge originally treating poultry slaughterhouse wastewater. The evolution of the biofilm in the polyurethane foam matrices was assessed during seven experimental phases which were thus characterized by the changes in the organic matter concentrations as COD (1.0 to 20.0 g/L). Biomass characterization proceeded with the examination of sludge samples under optical and scanning electron microscopy. The...

Autores: Mantilla,Samira Pirola Santos; Santos,Érica Barbosa; Vital,Helio de Carvalho; Mano,Sérgio Borges; Freitas,Mônica Queiroz de; Franco,Robson Maia.
This work investigated the effects of different packaging methods (air and vacuum) combined with irradiation (0.0, 2.0 and 3.0 kGy) on the preservation of chicken breast fillets stored at 1ºC for up to 18 days by sensorial test, determination of pH and bacterial growth. The findings indicated that the post-irradiation lag phase increased with the dose, leading to an extension in shelf-life. Vacuum-packed samples irradiated at 3.0 kGy exhibited the longest shelf life. Among the analyzed bacteria, coliforms and Listeria spp. were most sensitive to gamma radiation. All the fillets acquired more attractive coloration and better overall impression with irradiation. The combined use of vacuum packaging and irradiation (3.0 kGy) reduced the microbial populations...

Autores: Cansian,Rogério Luis; Floriani,Salete Teresa Radeski; Valduga,Eunice.
This work is focused on identifying microbial contamination in the scalding asepsis and cooling processes as well as in fresh sausages obtained. Salmonella was identified in two scald water samples but was absent in the water from chiller and in the final product, which might be explained in terms of chlorine addition and temperature reduction. The analysis revealed that MPN of Escherichia coli was in the range of &lt;1-11/mL in the scald water and &lt;1-64/mL in the chiller. Aeromonas sp. count showed 5 to 3.5x10¹ CFU/mL in the scald water and 9 to 3.7x10² CFU/mL in the chiller, probably due to the psycrophile characteristics of Aeromonas and evisceration process. The analysis of fresh sausages chicken revealed a sharp increase in the Aeromonas count...

Autores: Oliveira,Gislene B. de; Favarin,Luciana; Luchese,Rosa H.; McIntosh,Douglas.
The occurrence of psychrotrophic bacteria in raw milk is studied worldwide due to the difficulties associated with controlling their growth during cold storage and the consequent negative effects upon fluid milk or dairy products. Among the psychrotrophic bacteria, the genus Pseudomonas (represented primarily by P. fluorescens) has been highlighted as the cause of numerous defects in dairy products. In light of its perceived predominance, this species has frequently been chosen as a model organism to assess the effects of psychrotrophic bacteria on milk or to evaluate the efficacy of control measures. However, recent findings derived from the application of molecular biological techniques have exposed a number of deficiencies in our knowledge of the...

Parmesan-type cheeses are the most consumed special cheeses in Brazil. It is generally sold in retail shops, either grated or in wedge-shaped pieces, and its quality varies considerably, which is reflected directly in its price. There is lack of processing standardization and, since the ripening period is fundamental for the quality of this hard, semi-fat cooked cheese, this stage seems to be the thin line between low and high quality products. It is important to note that the Italian Parmegiano Reggiano is matured for a period of twelve months, as well as its rival Grana Padano, and this long ripening period causes changes making them gourmet, highly-valued cheeses. In the present study, twelve different Parmesan-type cheeses were purchased from the...

Approaches for in silico finishing of microbial genome sequences
Provedor de dados: 74
Autores: Kremer,Frederico Schmitt; McBride,Alan John Alexander; Pinto,Luciano da Silva.
Abstract The introduction of next-generation sequencing (NGS) had a significant effect on the availability of genomic information, leading to an increase in the number of sequenced genomes from a large spectrum of organisms. Unfortunately, due to the limitations implied by the short-read sequencing platforms, most of these newly sequenced genomes remained as “drafts”, incomplete representations of the whole genetic content. The previous genome sequencing studies indicated that finishing a genome sequenced by NGS, even bacteria, may require additional sequencing to fill the gaps, making the entire process very expensive. As such, several in silico approaches have been developed to optimize the genome assemblies and facilitate the finishing process. The...

ABSTRACT: The limitation of nitrogen is considered one of the most important factors for the Brazilian pastures degradation. However there are evidences that pastures formed by some species of Brachiaria could be benefited by the biological nitrogen fixation (BNF) guaranteeing a higer longevity to these pastures. Previus studies showed that the diazotrophic bacteria found inassociation with Brachiaria were mainly from the Azospirillum amazonense specie. Since associations between these microorganisms and plants are generally conditioned by the vegetation, it is possible that different Brachiaria genotypes can exercise a selective effect on the Azospirillum populations. The aim of this work was to study the intra-specific diversity of A. amazonense isolates...

RESUMO: A grande variedade de fitofisionomias existentes no Bioma Cerrado tem sido associada a diferentes fatores ambientais como clima, relevo, geologia, entre outros. O fator solo exerce influência fundamental nessa diversidade ambiental. As suas características químicas, físico-hídricas e biológicas formam um complexo de inter-relações, muitas vezes, difícil de analisar. A atuação do componente biológico nos solos de Cerrado ainda é pouco estudada. Das populações que compõem a microbiota, as micorrizas são reconhecidamente de grande importância nos ambientes oligotróficos ou sujeitos a qualquer tipo de restrição. Haja vista a ampla ocorrência de solos distróficos no Cerrado, pode-se supor que as micorrizas têm importante papel na composição das...

Microrganismos e disponibilidade de fósforo (P) nos solos: uma análise crítica.
Provedor de dados: 14
Autores: MENDES, I. de C.; REIS JUNIOR, F. B. dos.
ABSTRACT: Cerrado soils are extremely old, highly weathered and depleted in essential nutrients, especially P. For this reason, the addition of P fertilizers is mandatory in order to obtain economical yields of annual crops. Soil microorganisms play a key role in the P cycle. The P immobilized in the soil microbial biomass acts as reservoir of this element. Soil microorganisms also produce enzymes that act in the P mineralization, participate in the solubilization of inorganic phosphorus and are able to form symbiosis with plants, denominated mycorrizha, enhancing the uptake of this element. In this review we discuss the results of several studies evaluating the use of soil microorganisms to increase P availability in soils, some of the difficulties...

A alta dependência de importação de fertilizantes potássicos, além de elevar os custos de produção, deixa a agricultura vulnerável às oscilações do mercado externo, reduzindo a competitividade do agronegócio brasileiro, interna e externamente. Este forte obstáculo para a agricultura levou o governo brasileiro a instituir, em 22 de janeiro de 2021, por meio do Decreto nº 10.605, um Grupo de Trabalho Interministerial com a finalidade de desenvolver o Plano Nacional de Fertilizantes. Ele tem por objetivo fortalecer políticas de incremento da competitividade da produção e da distribuição de insumos e de tecnologias para fertilizantes no País, de forma sustentável, abrangendo adubos, corretivos, condicionadores e novas tecnologias, para diminuir a dependência...

Micorrizas: da associação mutualística com algodoeiro aos benefícios.
Provedor de dados: 14
Autores: COSTA, M. M. M. N.
Devido aos problemas supracitados trazidos pela Revolução Verde, foi necessário uma nova mudança de paradigmas na produção agropecuária. Particularmente no que se refere à fertilidade do solo e à nutrição da planta, foi preciso mudar o foco das pesquisas científicas, uma vez que corretivos e adubos solúveis traziam consigo a ideia de ‘alimentar a planta’ com elementos minerais, sendo o solo um mero suporte mecânico para as raízes. Dessa forma, para manter a sustentabilidade da produção vegetal, era necessário um novo conceito, pautado em ‘construção do solo’, com insumos que melhorassem a longo prazo as características químicas, físicas e biológicas do solo, a exemplo de adubação orgânica, adubação verde, bactérias fixadoras de nitrogênio atmosférico e...

In 1996, mean power output was 4160 MW with a cooling flow rate of 213 m3 / sec leading to an outfull vT of 9°26. The major impact of chloration is due to bromoform (18.3 ug / 1) in outflow. The amplitude of the vibrio annual cycle is stable when compared to previous years but diversity increases. In 1996, earlyness in species reproduction was noticeable. Chlorophyll biomass reached 45 mg / m3 and noctiluca cycle was quite unusual. Impact is estimated aroud 20 - 40 % in phytoplankton biomass and 30 - 100 % in zooplankton, depending on the species. Subtidal abra alba populations have been studied. For intertidal populations disappearance of spio martinensis is to be...

Autores: Dupont, Samuel; Carre-mlouka, Alyssa; Domart-coulon, Isabelle; Vacelet, Jean; Bourguet-kondracki, Marie-lise.
Combining culture-dependent and independent approaches, we investigated for the first time the cultivable fraction of the prokaryotic community associated with the carnivorous sponge Asbestopluma hypogea. The heterotrophic prokaryotes isolated from this tiny sponge were compared between specimens freshly collected from cave and maintained in aquarium. Overall, 67 isolates obtained in pure culture were phylogenetically affiliated to the bacterial phyla Proteobacteria, Bacteroidetes, Actinobacteria, and Firmicutes. This cultivable diversity was lower than the prokaryotic diversity obtained by previous pyrosequencing study and comparable to that of another Mediterranean demosponge, the filter-feeding Phorbas tenacior. Furthermore, using fluorescence in situ...

Approche microbiologique de l'anchoitage.
Provedor de dados: 5
Autores: Campello, Francois.
The maturation of salted anchovies leads to a product of particular organoleptic properties. The manufacturers have to resolve many problems. A thorough investigation of the phenomenons which occur is necessary to resolve them. The maturation is conducted at different temperatures. The present paper reports the microbiological variations of the present microfloras, from hyper-halophilic to the non-halophilic, which escort organoleptical and biochemical ones chiefly at 20 degree C. If the maturation's temperature is maintained high (28 degree C) there is a strong proteolysis. At 20 degree C the organoleptical characters appear within 2 months.

Olleya marilimosa gen. nov., sp nov., an exopolysaccharide-producing marine bacterium from the family Flavobacteriaceae, isolated from the Southern Ocean
Provedor de dados: 5
Autores: Nichols, Carol Mancuso; Bowman, John; Guezennec, Jean.
A Gram-negative, aerobic, gliding, orange-yellow marine bacterium was isolated from particulate material sampled from the Southern Ocean. This strain produced an exopolysaccharide in liquid culture. 16S rRNA gene sequence analysis showed that this isolate was a member of the family Flavobacteriaceae, but represented a separate lineage. Major whole-cell fatty acids included i15:1 omega 10c, i15:0, beta-OH i15:0, a15:1 omega 10c, 15:0 and alpha-OH i15:0. The G+C content of the DNA was 49 mol%. Based on phylogenetic, phenotypic, chemotaxonomic and genotypic analyses, this bacterium was placed in a novel taxon as Olleya marilimosa gen. nov., sp. nov. with type strain CAM030(T) (=ACAM 1065(T)=CIP 108537(T)).

Autores: Le Guyader, Soizick; Garry, Pascal; Ollivier, Joanna; Piquet, Jean-come.
The shellfish safety has long been considered a public health problem. The implementation of a regulation based on a bacterial indicator of faecal contamination has significantly reduced outbreaks of bacterial origin. However, epidemics of viral gastroenteritis due to the presence of noroviruses from human sewage persist. We demonstrated few years ago that oysters are not just a passive filter but are able to select some viral strains, via the presence of specific ligands, very similar to ligands observed in humans for these same virus. Ongoing developments, in conjunction with the application of metagenomic tools, will allow us to better understand the fate of some human pathogens after their release into the coastal environment.

Balneola vulgaris gen. nov., sp nov., a member of the phylum Bacteroidetes from the north-western Mediterranean Sea
Provedor de dados: 5
Autores: Urios, Laurent; Agogue, Hélène; Lesongeur, Francoise; Stackebrandt, Erko; Lebaron, Philippe.
A novel aerobic, Gram-negative bacterium, named 13IX/A01/164(T), was isolated from surface waters in the coastal north-western Mediterranean Sea. Cells were motile, straight rods, 2-5 mu m long and 0-2 mu m wide, and formed orange colonies on marine agar medium. The G+C content of the genomic DNA of strain 13IX/A01/164T was 42 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed the strain in the phylum Bacteroidetes within the family Crenotrichaceae. On the basis of 16S rRNA gene sequence comparison and physiological and biochemical characteristics, this isolate represents a novel species of a new genus, for which the name Balneola vulgaris gen. nov., sp. nov. is proposed. The type strain of Balneola vulgaris is 13IX/A01/164T (=DSM 17893T=CIP...

A laboratory model system for analysing microbial interactions occurring in anoxic estuarine sediments.
Provedor de dados: 5
Autores: Herbert, R; Keith, S.
Defined mixed populations of Clostridium butyricum, Desulfovibrio desulfuricans and Chromatium vinosum co-existed for long periods when grown in a single stage chemostat with glucose as sole carbon source. The nature and availability of the inorganic nitrogen source exerted a major effect on carbon flow in the experimental system. The data show that both the C. butyricum and D. desulfuricans isolates can utilise NO sub(3) as an e super(-)acceptor with an increase in cell yield. Under these growth conditions the free S super(2-) levels were lower resulting in more stable mixed populations. In addition the data show that the C. butyricum produces more oxidised fermentation end-products (acetate) when NO sub(3) super(-) was available and more reduced products...

In invertebrates, defensins were found in arthropods and in the mussels. Here, we report for the first time the identification and characterization of a defensin (Cg-Def) from an oyster. Cg-def mRNA was isolated from Crassostrea gigas mantle using an expressed sequence tag approach. To gain insight into potential roles of Cg-Def in oyster immunity, we produced the recombinant peptide in Escherichia coli, characterized its antimicrobial activities, determined its solution structure by NMR spectroscopy, and quantified its gene expression in vivo following bacterial challenge of oysters. Recombinant Cg-Def was active in vitro against Gram-positive bacteria but showed no or limited activities against Gram-negative bacteria and fungi. The activity of Cg-Def was...

In French Polynesia, black pearl cultivation now takes place on about 30 of the 118 atolls or islands. This activity has largely replaced copra, coconut oil and fishing as a source of income. Around 1,000 pearl farms, generally small ones of less than 5 ha, are registered. The pearl farms are mainly owned by families. In 1998, about 7,000 persons were employed in theentire pearl industry, from production to retailing. In value, this activity represents the first exportation of French Polynesian products. From 1988 to date, exports increased exponentially before leveling. Starting with less than two kilograms in 1972, exports have now stabilized at Il tons of "black" pearls.

Autores: Beaufort, Annie; Cardinal, Mireille; Le-bail, Alain; Midelet-bourdin, Graziella.
The aim of this study was to investigate the impact of superchilling (-2 degrees C) on the evolution of Listeria monocytogenes and organoleptic characteristics of cold-smoked salmon samples. An Hadamard matrix experimental design was carried out on artificially inoculated samples stored at +4 degrees C for 10 d and at +8 degrees C for 18 d to know the influence of four factors: salt content, strain, cold stiffening and superchilling time, on the level of L.monocytogenes in cold-smoked salmon. The growth of L. monocytogenes in naturally contaminated cold-smoked salmon and the organoleptic properties were investigated under superchilling conditions. Superchilling (-2 degrees C for 28 d) had a limited impact on some of the organoleptic properties but the...

Evaluation of the heterotrophic activity in waters by microanalytical methods.
Provedor de dados: 5
Autores: Bertoni, R.
The radiochemical methods proposed for evaluating heterotrophic activity in waters have been severely criticized in recent years because they are not considered to be sufficiently realistic. Thus, the possibility of directly measuring the heterotrophic consumption of naturally occurring Organic Carbon (OC) in fresh water samples incubated under controlled conditions has been evaluated. The analytical performances of two OC analyzers utilizable for this purpose are discussed here, and some examples of the results obtained by the direct measurement of OC consumption are presented. The consumption rates thus measured ranged from 11.6 to 50.2 mu gC/ 1.h. Although the technique discussed here is less sensitive than radiochemical methods, the few assumptions...

Variations metaboliques des communautes bacteriennes lors d'une pollution par petrole brut, avec ou sans traitement
Provedor de dados: 5
Autores: Cauchi, B.
Metabolic potentialities of bacterial communities in marine water after Crude Oil pollution (Arabian Light) and in marine water after pollution and treatment (enrichment: Inipol EAP 22) have been studied and compared. With data analysis: regressions, hierarchical ascending classification and multifactor correspondence analysis, the treatment gives rise to conservation and one increase of enzymatic pool (second day) of the bacterial sample as a combined metabolic homogeneity contrary to pollution impact. The direct assimilation of hydrocarbons looks more regular and slow without treatment.

Etude de la diversité métabolique des micro-organismes des sources hydrothermales
Provedor de dados: 5
Autores: Byrne, Nathalie.
Since the discovery of oceanic hydrothermal vents, microbial diversity of this extreme environment was studied using both cultivation and molecular approaches. In this study the microbial diversity of active chimney from both TAG and Lucky Strike sites (Mid Atlantic Ridge) was investigated using both molecular survey and continuous enrichment culture in a bioreactor. To reproduce as close as possible environmental conditions the cultures were performed in oligotrophic conditions, in the presence of hydrogen and carbondioxide in the gas sweeping mix or using in situ sampled fluid/sea water mix as culture medium. The effect of environmental changes such as temperature and the absence or presence of sulphur was also investigated. Archaeal and Bacterial...

Human and animal enteric caliciviruses in oysters from different coastal regions of the United States
Provedor de dados: 5
Autores: Costantini, V; Loisy, Fabienne; Joens, L; Le Guyader, Soizick; Saif, L.
Food-borne diseases are a major cause of morbidity and hospitalization worldwide. Enteric caliciviruses are capable of persisting in the environment and in the tissues of shellfish. Human noroviruses (HuNoVs) have been implicated in outbreaks linked to shellfish consumption. The genetic and antigenic relatedness between human and animal enteric calliciviruses suggests that interspecies transmission may occur. To determine the occurrence of human and animal enteric calliciviruses in United States market oysters, we surveyed regional markets. Oysters were collected from 45 bays along the United States coast during the summer and winter of 2002 and 2003. Samples were analyzed by reverse transcription-PCR, and results were confirmed by hybridization and...

Autores: Dauchy Silbande, Adele; Adenet, Sandra; Smith-ravin, Juliette; Joffraud, Jean-jacques; Rochefort, Katia; Leroi, Francoise.
Metagenomic, microbial, chemical and sensory analyses of Thunnus albacares from Martinique and stored in ice (AIR – 0 °C), vacuum (VP – 4/8 °C) and modified atmosphere packaging (MAP – 4/8 °C) (70% CO2 – 30% O2) were carried out. The organoleptic rejection of AIR tuna was observed at day 13 when total bacterial counts equaled 106–107 CFU g−1. No extension of shelf-life was provided by VP and MAP. According to 16S rRNA gene sequence analyzed by Illumina MiSeq and PCR-TTGE, Rhodanobacter terrae was the main species of the freshly caught tuna. At the sensory rejection time, Brochothrix thermosphacta and Pseudomonas dominated the AIR products while B. thermosphacta alone or a mix of B. thermosphacta, Enterobacteriaceae and lactic acid bacteria (LAB) dominated...

Bacterial biofilms with emphasis on coagulase-negative staphylococci
Provedor de dados: 80
Autores: Oliveira,A; Cunha,MLRS.
In addition to their capacity to attach to surfaces, various groups of microorganisms also produce an extracellular polymeric substance known as "slime". This slime forms a thin layer around cells known as biofilm. Thus, biofilm structure comprises bacterial cells and an extracellular polymeric substance. It also presents a defined architecture, providing the microorganisms with an excellent protective environment and favoring the exchange of genetic material between cells as well as intercellular communication. The ability to produce biofilm is observed in a large group of bacteria, including coagulase-negative staphylococci (CNS) which are the predominant microorganisms of normal skin flora and have been implicated as the causative agents of hospital...
