ABSTRACT

This study deals with production and characterization of biosurfactant from marine actinomycetes which isolated from east coast region of Nagapattinam beach in Tamil Nadu. The production of the biosurfactant was found to be higher in medium containing sucrose and lower in the medium containing glycerol. Yeast extract was the best nitrogen source for the production of the biosurfactant. The purified biosurfactant was shown strong antimicrobial activity and antioxidant activity. The biosurfactant was produced from the marine Streptomyces sp. using non-hydrocarbon substrates such as sucrose that was readily available and not required extensive purification procedure. Streptomyces species N11 can be used for microbially enhanced oil recovery process.
