Assessment of Antimicrobial Property of a Secondary Metabolite Produced by an Enriched Bacterial Culture Isolated from Soil

The soil harbors diverse microorganisms which are more beneficial. The microorganisms produce many secondary metabolites which are commercially exploited in many applications. The antibiotic is an important secondary metabolite which is secreted by the soil microorganisms. Hence our research focuses on the screening and isolation of potential secondary metabolites producing organism from the soil. The antimicrobial activity was assessed by Kirby Disc diffusion method and the extract had good inhibition activity against both bacterial and fungal pathogenic organisms. The sample extract showed maximal antifungal activity against Aspergillus niger with 24 mm (zone of clearance).
