Isolation and identification of antibiotic-producing actinomycetes

Abstract

Fourteen actinomycetes strains were isolated from soils in different locations in hilla city. Antibacterial Primary screening assays showed that five isolates were the most potential antibacterial producers, whereas three isolates had antifungal activity when evaluated by antifungal primary screening assays. Among all these isolates, strain 40A was the most active isolate against pathogenic bacteria and fungi. The characteristics of isolate were studied at the morphological, cultural and physiological level. From the characteristics of strain 40A, the isolate was not Streptomyces, but it could be pseudonocardia for the similarities between them.
