ISOLATION AND CHARACTERIZATION OF BIOSURFACTANT PRODUCING PSEUDOMONAS SP ISOLATED FROM PORTO NOVO COASTAL REGION ? CUDDALORE

Biosurfactants are amphiphilic compounds produced by microorganisms as secondary metabolite. Biosurfactants are microbially produced surface active agents and occur in nature as chemical entities such as glycolipids, phospholipids and lipopeptides. These molecules have attracted considerable scientific attention due to lower toxicity, higher biodegradability. The present study deals with the screening, production and characterization of a biosurfactant by Pseudomonas sp (PNB 34 and PNB 51) from the sediment samples of Porto Novo coastal region,Cuddalore, Tamil Nadu. Thus, the nature of the biosurfactants produced from the isolates in our study was a rhmnolipid - type. They had a good oil displacement( 2.2), β haemolytic and emulsifying properties (52.6) The obtained results suggests that the marine isolates has got the great industrial importance. .
