A note on stability in food matrices of Salmonella enterica serovar Enteritidis-controlling bacteriophages Electron. J. Biotechnol.
Robeson,James; Turra,Gabriel; Huber,Karen; Borie,Consuelo.
Background Lytic bacteriophages are bacterial viruses that upon infection kill their host cells and therefore have re-emerged as biological control agents of bacterial pathogens, particularly in the field of food related infections. Here, we investigated the stability in different food matrices of five phage isolates capable of controlling the foodborne pathogen Salmonella enterica serovar Enteritidis (SE). Results We found that two phages, originally isolated from food sources, were up to 5 logs more stable than three phages isolated from sewage, in ten food matrices (fresh and processed) at both 4°C and 18°C. Conclusion Lytic phages isolated from contaminated food sources seem to be a better choice when structuring phage cocktails to be used in the...

Antagonism of yeasts to Xanthomonas campestris pv. campestris on cabbage phylloplane in field Rev. Microbiol.
Assis,Sayonara M.P.; Mariano,Rosa L.R.; Michereff,Sami J.; Silva,Gil; Maranhão,Elizabeth A.A..
Twenty yeast isolates, obtained from cabbage phylloplane, were evaluated for antagonistic activity against Xanthomonas campestris pv. campestris, in field. Plants of cabbage cv. Midori were pulverized simultaneously with suspensions of antagonists and pathogen. After 10 days, plants were evaluated through percentage of foliar area with lesions. Percentage of disease severity reduction (DSR%) was also calculated. Yeast isolates LR32, LR42 and LR19 showed, respectively, 72, 75 and 79% of DSR. These antagonists were tested in seven different application periods in relation to pathogen inoculation (T1=4 d before; T2=simultaneously; T3=4 d after; T4=4 d before + simultaneously; T5=4 d after + simultaneously; T6=4 d before + 4 d after; T7=4 d before +...

Biocontrol potential of saline- or alkaline-tolerant Trichoderma asperellum mutants against three pathogenic fungi under saline or alkaline stress conditions BJM
Guo,Ruiting; Wang,Zhiying; Huang,Ying; Fan,Haijuan; Liu,Zhihua.
ABSTRACT Salinity and alkalinity are major abiotic stresses that limit growth and development of poplar. We investigated biocontrol potential of saline- and alkaline-tolerant mutants of Trichoderma asperellum to mediate the effects of salinity or alkalinity stresses on Populus davidiana × P. alba var. pyramidalis (PdPap poplar) seedlings. A T-DNA insertion mutant library of T. asperellum was constructed using an Agrobacterium tumefaciens mediated transformation system; this process yielded sixty five positive transformants (T1–T65). The salinity tolerant mutant, T59, grew in Potato Dextrose Agar (PDA) containing up to 10% (1709.40 mM) NaCl. Under NaCl-rich conditions, T59 was most effective in inhibiting Alternaria alternata (52.00%). The alkalinity...

Biological control of mycotoxin-producing molds Ciência e Agrotecnologia
Medeiros,Flávio Henrique Vasconcelos de; Martins,Samuel Julio; Zucchi,Tiago Domingues; Melo,Itamar Soares de; Batista,Luis Roberto; Machado,José da Cruz.
Mycotoxins are produced by the secondary metabolism of many fungi and can be found in almost 25% of the world's agricultural commodities. These compounds are toxic to humans, animals, and plants and therefore, efforts should be made to avoid mycotoxin contamination in food and feed. Besides, up to 25% of all harvested fruits and vegetables are lost due to storage molds and/or mycotoxin contamination and many methods have been applied to mitigate these issues, but most of them rely on the use of fungicides. Although chemicals are often the first defensive line against mycotoxigenic fungi, the indiscriminate use of fungicides are awakening the public perception due to their noxious effects on the environment and human/animal health. Thus, there is an...

Biological control of rice brown spot with native isolates of three Trichoderma species BJM
Khalili,Elham; Sadravi,Mehdi; Naeimi,Shahram; Khosravi,Vahid.
Brown spot caused by Bipolaris oryzae is an important rice disease in Southern coast of Caspian Sea, the major rice growing region in Iran. A total of 45 Trichoderma isolates were obtained from rice paddy fields in Golestan and Mazandaran provinces which belonged to Trichoderma harzianum, T. virens and T. atroviride species. Initially, they were screened against B. oryzae by antagonism tests including dual culture, volatile and nonvolatile metabolites and hyperparasitism. Results showed that Trichoderma isolates can significantly inhibit mycelium growth of pathogen in vitro by producing volatile and nonvolatile metabolites Light microscopic observations showed no evidence of mycoparasitic behaviour of the tested isolates of Trichoderma spp. such as coiling...

Biological potential of fungi associated to Prays oleae in Trás-os-Montes (Northeastern region of Portugal) IPB - Escola Superior Agrária
Oliveira, Ivo; Baptista, Paula; Lino-Neto, Teresa; Bento, Albino; Pereira, J.A..
Olive groves represent an important fraction of the agricultural practices in Portugal, mainly in the region of Trás-os-Montes. Our work pretends to disclose the fungal diversity associated to one of the major olives pests, the Prays oleae Bern. Besides evaluating the extent of the presence of entomopathogenic fungi, we also intend to reveal other promising fungi with potential to be used as biological control agents. In order to achieve this goal, larvae and pupae of the three generations of P.oleae were collected from several orchards. Whenever a fungal agent was associated to the cause of death, we proceeded to the preparation of fungal pure cultures, DNA isolation, amplification and sequencing of their ITS region for species identification. High fungal...

Caenorhabditis elegans as an indicator of toxicity of Bacillus thuringiensis strains to Meloidogyne incognita race 3 Ciência Rural
Montalvão,Sandro Coelho Linhares; Castro,Marcelo Tavares de; Soares,Carlos Marcelo Silveira; Blum,Luiz Eduardo Bassay; Monnerat,Rose Gomes.
ABSTRACT: The cotton plant (Gossypium hirsutum) is affected by several diseases of economic importance, among them root-knot nematode (Meloidogyne incognita races 3 and 4). Methods to control this disease include the application of nematicides, solarization, deep plowing, crop rotation and use of antagonistic microorganisms. Among species of Bacillus, there are strains that act as bioregulators and antagonists of several pathogens. Tests to identify these strains are hampered by the difficulty of obtaining large populations of the pathogen and by the time of execution of the in vivo tests that should be conducted for about 90 days. The objective of this research was to compare the toxicity of B. thuringiensis strains to two nematodes, M. incognita and...

Control of Listeria monocytogenes growth in soft cheeses by bacteriophage P100 BJM
Silva,Elaine Nóbrega Gibson; Figueiredo,Ana Cláudia Leite; Miranda,Fernanda Araújo; Almeida,Rogeria Comastri de Castro.
The purpose of this study was to determine the effect of bacteriophage P100 on strains of Listeria monocytogenes in artificially inoculated soft cheeses. A mix of L. monocytogenes 1/2a and Scott A was inoculated in Minas Frescal and Coalho cheeses (approximately 10(5) cfu/g) with the bacteriophage added thereafter (8.3 x 10(7) PFU/g). Samples were analyzed immediately, and then stored at 10 ºC for seven days. At time zero, 30 min post-infection, the bacteriophage P100 reduced L. monocytogenes counts by 2.3 log units in Minas Frescal cheese and by 2.1 log units in Coalho cheese, compared to controls without bacteriophage. However, in samples stored under refrigeration for seven days, the bacteriophage P100 was only weakly antilisterial, with the lowest...

Control potential of Meloidogyne javanica and Ditylenchus spp. using fluorescent Pseudomonas and Bacillus spp. BJM
Turatto,Marcielly F.; Dourado,Fernanda dos S.; Zilli,Jerri E.; Botelho,Glória R..
ABSTRACT Plant Growth Promoting Rhizobacteria (PGPR) have different mechanisms of action in the development of plants, such as growth promotion, production of phytohormones and antibiotic substances and changes in root exudates. These help to control plant diseases. In order to evaluate the potential of microorganisms in the control of Meloidogyne javanica and Ditylenchus spp., five rhizobacteria isolated from rhizosphere of garlic cultivated in the Curitibanos (SC) region were tested. Hatching chambers were set on Petri dishes, in which were added 10 mL of bacterial suspension and 1 mL of M. javanica eggs suspension, at the rate of 4500, on the filter paper of each chamber. The same procedure was performed with 300 juvenile Ditylenchus spp. The...

DNA barcodes, expanded distribution, and redescription of Apanteles hemara Nixon, 1965 (Hymenoptera, Braconidae, Microgastrinae), a potential biocontrol species against amaranth leaf-webbers in Africa Naturalis
Fernandez-Triana, J.; Beaudin, M.; Achterberg, K. van; Agbodzavu, M.K.; Othim, S.T.O.; Nyamu, F.W.; Fiaboe, K.K.M..
The microgastrine parasitoid wasp Apanteles hemara Nixon, 1965, is currently being considered as a potential biocontrol agent of amaranth leaf-webber pests in Africa. To facilitate future research and identification of the species, we characterize it from an integrative taxonomy perspective by providing a comprehensive morphological redescription, extensive illustrations (including the first images of the holotype), DNA barcodes, wasp biology, host data (Choreutidae and Crambidae caterpillars), and updated geographical distribution of the species (including eight new country records). Despite a wide distribution across four major biogeographical regions (mostly within the Old World tropics), the species seems to be relatively uniform from a molecular and...

Effect of organic amendments on sclerotial germination, mycelial growth, and Sclerotium rolfsii-induced diseases Trop. Plant Pathol.
Blum,Luiz E. B; Rodríguez-Kábana,Rodrígo.
The addition of organic residues to soil is an option to control some soil-borne diseases. Benzaldehyde and powders of kudzu (Pueraria lobata), velvetbean (Mucuna deeringiana), and pine-bark (Pinus elliottii and P. taeda) added to soil could reduce certain soil-borne diseases. This study evaluated the effects of benzaldehyde and the dried powders of kudzu, velvetbean, and pine-bark as soil amendments on germination and formation of sclerotia, on mycelial growth of Sclerotium rolfsii, on plant survival, and disease incidence. The data showed that high amounts of benzaldehyde (0.4 ml kg-1 of soil) and velvetbean (100 g kg-1) inhibited S. rolfsii mycelial growth and sclerotium germination. However, low amounts of benzaldehyde (0.1 ml kg-1), kudzu (25 g kg-1),...
