Biosurfactants are a unique class of structurally diverse compounds, which are amphiphilic in nature and have pronounced surface active properties with a wide variety of applications related to environmental protection, enhanced oil recovery, cosmetic, food processing and pharmaceutical industries (1-6). These compounds have been shown to have several advantages including high biodegradability, biocompatibility, low toxicity and low irritancy over their synthetic counterparts (7). However, a major concern behind the restricted commercial application of these microbially produced biosurfactants is their high production costs (6, 8, 9). This cost can be reduced by utilizing alternative substrates, such as agricultural based industrial wastes, for economical biosurfactant production, and the choice of microorganism, which plays an important role in biosurfactant production. A wide variety of alternative raw materials, namely various agricultural and industrial byproducts, have been evaluated for biosurfactant production (8-11). Keeping the above factors into account, modified minimal salt medium supplemented with potato peels was selected and used as the sole carbon source for production of biosurfactant. India being the third largest producer of potato in the world (10) generates large quantities of potato peels, which are generally attained by steam, abrasive or lye peeling by potato processing industries.
