Surfactants are amphiphilic chemicals with emulsification and surface tension lowering properties that enable their use as foaming and dispersing agents. There is a growing demand for sur- factants; however, as they are synthesized from petrochemicals or palm oil [1], they are increasingly expensive and can be envi- ronmentally unfriendly. For these reasons, production of "green" biosurfactants from renewable resources has received considerable attention in recent years. Biosurfactants, synthesized by microorganisms, consist of sugars, fatty acids and amino acids 12,3]. Examples of micro- bially derived biosurfactants include rhamnolipids, sophorolipids,
