Partial Purification and Characterization of Biosurfactant from Pseudomonas Aeruginosa

Biosurfactant are an amphiphilic compound produced by various bacteria and fungi which reduces surface and interfacial tensions by accumulating at the interface of immiscible fluids and increase the surface areas of insoluble compounds leading to increased mobility. These molecules have attracted considerable scientific attention due to lower toxicity, higher biodegradability. The present study deals with the screening, production and partial purification of a biosurfactant by Pseudomonas aeruginosa. The properties of biosurfactant that was separated by acetone precipitation. The biosurfactant produced was a rhmnolipid-type in nature. It had a good foaming and emulsifying activities.
