Many groups of microorganisms like Gram-positive, Gram-negative bacteria and fungi have the ability of synthesizing antimicrobial agents. The top cultivable antimicrobial agent producers present in soil are the actinomycetes.In fact, Streptomyces species are the resource of 75% of commercially produced and medically useful antibiotics.For this reasons to explore new antimicrobial metabolites,in total, 14 strains were isolated which showed various degrees of inhibition. Among them six strains which showed considerable inhibition against their test organisms were studied in details and their...
