Synthesis of biosurfactants from natural resources
Role of biosurfactants has shown renewed interest; hence, search for readily available natural resources of these materials is continuing. Chicken viscera and bahera oil were used as natural sources of oleic acid and its methyl ester, respectively, for the preparation of biosurfactants. Enzymatic es...
