The present study deals with the phytochemical contents, antimicrobial and antioxidative activities of bark tissue of Sonneratia caseolaris, a mangrove plant from Sundarban estuary, India. Phytochemical analyses revealed the presence of high amounts of phenolics, flavonoids, tannins, alkaloids and saponins. Antimicrobial efficacies of various extracts of S. caseolaris were assessed by disc diff...

members of the genus bacillus are among the most promising candidates for biological control of plant pathogenic bacteria. in this study, cell free supernatants of three strains b. subtilis utb96, b. subtilis utb1 and b. subtilis utb70 against aspergillus flavus r5 were investigated using dual culture assay. strain b. subtilis utb96 showed the highest inhibition effect. thin lyer chromatography...

BACKGROUND Antibiotics are usually assumed as secondary metabolites produced during the idiophase of microbial growth, which can kill or inhibit the growth of other microorganisms. Nowadays, indiscriminate use of antibiotics has resulted in resistant microorganisms. Therefore, screening researches on products with antimicrobial activities are necessary. OBJECTIVES To find new antibiotics to d...
