In screening of new antibiotics, several actinomycetes were isolated from soil samples. Crowded plate technique was used for the isolation of actinomycetes. The morphological and cultural characterization of A-4 strain was performed. In medium formulation study for A-4 and A-4 mutant, various carbon and nitrogen sources were tested for maximum antibiotic production using zone of inhibition and packed cell volume (%) as parameters. Various fermentation conditions like pH, temperature and DO2 were also optimized for the maximal production of antibiotic from both A-4 and A-4 mutant. All medium formulation as well as bioprocess parameters for A-4 and A-4 mutant strains was compared. Some actinomycetes strains, showed promising antimicrobial scores against different strains of bacteria and fungi. From the six strains selected, one strain designated as A-4 showed maximum antimicrobial property against gram positive and gram negative strains as well as various fungi. Morphological and cultural studies showed that A-4 is belongs to actinomycete genus.. The strain A-4 and A-4 mutant was found to be having better antimicrobial activity in comparison with other soil isolates of actinomycetes.
