The use of novel isolates of Trichoderma with efficient antagonistic capacity against Fusarium oxysporum f. sp. lycopersici (FOL) is a promising alternative strategy to pesticides for tomato wilt management. We evaluated the antagonistic activity of 30 isolates of T. asperellum against 4 different isolates of FOL. The production of extracellular cell wall degrading enzymes of the antagonistic i...

Wild species of Bacillus spore formers were selectively isolated from various sources like Dry spices, Milk, Soil, Intestine of pig and Chicken .Probiotic potential of isolates were studied on the basis of non hemolysis, non lecithinase activity ,acid bile tolerance, resistance to artificial gastric and intestinal fluids and antagonistic action towards enteric pathogens such as Salmonella typhi...

Foodborne pathogens are among the most significant problems in maintaining the health of the population. In 2011 the CDC estimates that each year roughly 1 in 6 Americans (or 48 million people) gets sick, 128,000 are hospitalized, and 3,000 die of foodborne diseases. The leading causes of foodborne illnesses in the United States are Salmonella and Shigella [1,2]. Staphylococcus aureus is among ...

Cellocidin is an antibacterial antibiotic discovered by SUZUKI et al.1) Although the antibiotic shows an excellent preventive effect against rice bacterial leaf blight, its use is restricted because of its phytotoxicity to rice plants. OKIMOTO and MISATO2) demonstrated cellocidin inhibited the metabolism of a-keto-glutarate to succinate in Xanthomonas oryzae. TANAKA et al.3) also found that cel...

BACKGROUND Enteric fever is a global health problem, and rapidly developing resistance to various drugs makes the situation more alarming. The potential use of Lactobacillus to control typhoid fever represents a promising approach, as it may exert protective actions through various mechanisms. METHODS In this study, the probiotic potential and antagonistic activities of 32 Lactobacillus isola...

Studies have been carried out to substantiate the preparation’s composition, which includes a complex of probiotic with prebiotic. It was found that synbiotic basis is hydrolyzed lignin as prebiotic concentration 0.5 -2.0%, strain L. paracasei bacterial cells 48 B CFU/g high activity and optimal biological properties, such adhesive activity, antagonistic against enteropathogenic microorganisms ...

A bacterial strain (D38BY) belonging to the family Flavobacteriaceae and antagonistic towards an algicidal bacterium (strain S03; Flavobacteriaceae) was isolated from a culture of the red tide dinoflagellate Karenia brevis that had previously been characterized as resistant to attack by strain S03. This antagonistic bacterium increased the survival time of otherwise susceptible, bacteriafree K....

In light of public concerns over the use of pesticides and antibiotics in plant protection and the subsequent selection for spread of resistant bacteria in the environment, it is inevitable to broaden our knowledge about viable alternatives, such as natural antagonists and their mode of action. The genus Pseudomonas is known for its metabolic versatility and genetic plasticity, encompassing pat...

In this study, attempts were made to isolate Streptomyces sp. from soil samples of two different regions of Bangladesh and evaluate their antagonistic activity against fish and human pathogenic bacteria. A total of 10 isolates were identified as Streptomyces sp. based on several morphological, physiological and biochemical tests. Cross streak method was used to observe the antagonistic activity...
