The isolateswere screened for antimicrobial activity against 4 pathogenic fungi and 6 pathogenic bacteria. Among 63 isolates, 10 isolates showed antibacterial activity and 6 isolates showed antifungal activity. Among active isolates, isolate No. 18 showed highest antimicrobial activity against all the pathogenic bacteria and fungi studied and it was identified as Streptomyces species.
