Bio-active marine organism Streptomyces.fradiae is studied for its various physicochemical parameters by adopting methods like Gram’s staining, Acid fast staining, Motility test, Endospore staining, Indole production, Methyl Red and Voges-Proskauer (MR-VP) test, citrate utilization, Urease production, Carbohydrate fermentation, Triple sugar iron (TSI) test, Oxidase test, Catalase test, Nitrate reduction test , Melanin production, Xanthine/hypoxanthine/esculin/arbutin hydrolysis,Gelatin/casein/cellulose/ starch/tween20/tween 80 hydrolysis, Chitin/pectin hydrolysis,Haemoglobin hydrolysis. These studies prove that marine S.fradiae showed both positive and negative results for the above physiochemical studies. https://www.biotech-asia.org/vol11_nospl_edn1/physiochemical-studies-on-bio-active-marine-organism-streptomyces-fradiae/ Bio-active organisms; physicochemical parameters; primary screening of culture
