ISOLATION AND SCREENING OF SOIL BACTERIA FOR POTENTIAL ANTIMICROBIAL ACTIVITY

Abstract

Antimicrobial agents are the most promising field worldwide with the need of continuous search of new ones. Present study was to investigate and explore our indigenous soil microflora for antimicrobial production. Among 22 isolated organisms, 14 were identified as Bacillus sp., 5 were Pseudomonas sp. and 3 were Escherichia coli. One of the identified organisms as Escherichia coli was found to have activity against clinical isolates i.e. Cornybacterium pseudodiphtherieae, Pseudomonas vulgaris and Staphylococcus aureus and another identified Bacillus sp. showed high activity against Escherichia coli.
