Studies on bioactive metabolites produced by Lechevalieria flava

Abstract

Cultural, morphological and physiological characteristics of Lechevalieria flava were studied. The strain exhibited sensitivity to different types of antibiotics. It could tolerate salt concentration upto 4%. The isolate had the ability to produce enzymes such as amylase, chitinase, protease and urease. Growth pattern and antimicrobial properties of the strain were studied in different media. Impact of various carbon and nitrogen sources on the production of bioactive metabolites was also investigated. The secondary metabolite from L. flava was found to be active against bacteria like Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus and fungi such as Candida albicans. © 2007 Academic Journals Inc.
