BIOSURFACTANTS - MOVING TOWARDS INDUSTRIAL APPLICATION

Chemically synthesized surface-active compounds are widely used in the pharmaceutical, cosmetic, petroleum and food industries. However, with the advantages of biodegradability, and production on renewable-resource substrates, biosurfactants may eventually replace their chemically synthesized counterparts. So far, the use of biosurfactants has been limited to a few specialized applications because biosurfactants have been economically uncompetitive. There is a need to gain a greater understanding of the physiology, genetics and biochemistry of biosurfactant-producing strains, and to improve process technology to reduce production costs.
