Popis:	This study aimed to explore the antimicrobial and chitinase activity produced by potent marine Streptomyces against Escherichia coli, MRSA and Aspergillus terreus. The powdered shrimp shell (SS) was used as a mono-component medium and tested for their effect on the production of active metabolites against three pathogens and chitinase activity. Shrimp shell was used as production media for optimizing fermentation conditions. The tested medium supported production of bioactive metabolite. Shrimp shell at 5.0 gl-1 exhibited significant antagonistic activity against pathogenic microorganisms and produced chitinase in cell-free supernatants at value of 0.56 U/ml/h, while the greatest chitinase activity value of 10.36 U/ml/h was achieved when grown on the shrimp waste as a mono-component medium (40 gl-1 shrimp waste in tap water).
