The objective of this study was to identify and characterize lactic acid bacteria isolated from human milk, with an emphasis on their probiotic properties.The strains were tested for ability inhibit growth Enterococcus faecalis, Salmonella enterica subsp. serotype Enteritidis, Listeria monocytogenes, Staphylococcus aureus Escherichia coli, as well susceptibility antimicrobial agents pH bile salt tolerance. Gram-positive catalase-negative selected identified (83·3%) after sequencing the 16S...
Approximately 75% of the worldwide production hard natural fibers originates from sisal, an industrial crop arid and semiarid tropical regions. Brazil is world's largest producer sisal fiber, accounting for more than 40% production, bole rot disease has been main phytosanitary problem this crop. All previous studies reporting Aspergillus niger as causal agent were based on morphological features fungal isolates infected plant tissues in pure cultures. Black aspergilli are one most complex...
ABSTRACT The cocoa and palm oil agro-industries active in the state of Bahia, Brazil, generate high quantities lignocellulosic wastes that could be recycled through their use formulation substrates to cultivate edible mushrooms. Pleurotus ostreatus, also known as oyster mushroom, is second most cultivated mushroom world due its highly appreciated gastronomic, nutritional, medicinal characteristics. This work evaluated vertical mycelium growth, biological efficiency, yield, nutritional...
Objetivou-se, com este trabalho, avaliar os componentes agronômicos e o índice de colheita genótipos amendoim ereto rasteiro submetidos a 27 dias suspensão hídrica, no inicio da fase vegetativa. O experimento foi conduzido em casa vegetação sob delineamento inteiramente casualizado esquema fatorial 8 x 2 (genótipos tratamentos hídricos) cinco repetições. As variáveis analisadas foram: peso seco planta total, das raízes, altura haste principal, produção vagens planta-1, tolerância à seca....
Aspergillus welwitschiae is a species of the Nigri section genus Aspergillus. In nature, it usually saprotroph, decomposing plant material. However, causes bole rot disease Agave sisalana (sisal), used for extraction hard natural fibers, causing great economic loss to this culture. study, we isolated and sequenced one genome A. (isolate CCMB 674 (Collection Cultures Microorganisms Bahia)) from stem tissues sisal performed in silico wet lab experimental strategies describe its ability produce...
Aspergillus welwitschiae causes bole rot disease in sisal (Agave sisalana and related species) which affects the production of natural fibers Brazil, main worldwide producer fibers. This fungus is a saprotroph with broad host range. Previous research established A. as only causative agent field, but little known about evolution this species its strains. In work, we performed comparative genomics analysis 40 We show conflicting molecular identity species, one sisal-infecting strain sharing...
The objective of this work was to accomplish the isolation, molecular identification and characterizing physiology causal agent algal spot in mango trees. For purpose, pathogen growth assessed different culture media, with subsequent observation measurements filamentous cells. made using mycelium obtained from leaf lesions pure algae colonies grown medium. Descriptions based on DNA sequencing indicated that is Cephaleuros virescens. must be isolated primarily liquid medium for further...
The fungus Trichoderma spp. is known due to its versatility for promoting crop growth and grain yield, improving the nutrient absorption increasing yield. objective of this work was evaluate commercial strains an organomineral fertilizer in early promotion yield wheat plants. Thus, seeds cv. BRS 264 were treated with 2 mL a suspension (2.5 × 108 conidia mL-1 per 100 g seed) submitted laboratory until 8 days after sowing (DAS). In greenhouse experiment, sown L pot, which received 4.0 pot....
Papaya (Carica papaya L.) is susceptible to various production diseases, therefore, studies are needed reduce them.Papaya fruit rot (Phytophthora palmivora (Butler) Butler) one of the fungal diseases present in producing regions (Bahia and Espírito Santo) Brazil.This study aimed evaluate variability aggressiveness virulence Phytophthora that influence severity postharvest vitro vivo.The following mycelial growth characteristics were evaluated: (a) speed index (MGSI); (b) potential (%MGSI);...
Papaya (Carica papaya) is one of the most cultivated and consumed tropical fruit worldwide.Its production might be limited by preharvest postharvest diseases.The rot caused Phytophthora palmivora important diseases papaya in Brazil.The control these usually made with fungicide applications.Therefore, studies concerning biocontrol generate data that may reduce environmental impacts pesticides.Thus, biological Trichoderma an alternative to use fungicides for P. fruit.Four antagonists...
The increasing world production of biodiesel has resulted in an accumulation crude glycerol as the major byproduct.This could be used carbon source for industrial microbiology, with economic and environmental advantages industry.We explored Atlantic Rainforest soil sample to search glycerol-degrading microorganisms.Microcosms this were established containing minimal medium + 8% (w/w); biological activity was measured by respirometry.High CO 2 levels found some microcosms, suggesting...
In Brazil and in other countries of the world, studies have been conducted to identify Listeria monocytogenes cattle meat that is preferably consumed undercooked and, when marketed without meeting strict phytosanitary requirements, may cause outbreaks listeriosis. such, foodborne outbreaks, methods used for detection pathogen efficiency associated with them are crucial proper assessment. this study, we techniques biochemical molecular identification L. isolated from 30 samples fresh beef,...
Enterobacter and Bacillus are common endophytes in many plants. Endophytic cloacae 344 amyloliquefaciens 629 from cacao had their colonization patterns assessed different plants organs. The 344's all was ~12x higher than those observed for 629. CFU countings were 16 3 times lower 629, respectively, non-sterile sterile conditions. results suggested that is a better endophytic colonizer but this seems competitor 344. Indigenous fungi interfered with the levels of both strains Plant species,...
Agave sisalana, known as sisal, yields the world’s main natural stiff fiber used to produce various industrial products. The Brazilian semiarid is largest sisal producing region in world; however, production under threat by bole rot disease, caused Aspergillus welwitschiae. Since chemical control of this disease questionable drought-ridden areas with little investment crop management and due environmental public health concerns, search for a biocontrol agent against A. welwitschiae...
The papaya fruit rot (Phytophthora palmivora) is responsible for significant losses.To reduce diseases, especially in areas with climate and humidity favorable to pathogens, are adopted chemical methods, which sometimes increase the cost of production cause severe environmental impacts.Alternatively, there products, such as, phosphites potassium acibenzolar-S-methyl (ASM) that might be efficient on disease control less aggressive environment.Phosphites K ASM were evaluated this study...
The objective of this work was to accomplish the micromorphological characterization causal agent algal spot in ‘Amrapali’ mango trees. Therefore, leaves exhibiting symptoms spots were used for making microscope slides, on which pathogen somatic and reproductive structures measured. dimensions obtained sporangiophores sporangia 245.5-545.6 × 10.5-19.1 μm 21.4-34.2 16.3-24.7 μm, respectively. Descriptions based micromorphology indicated that algae...
