Abstract

AGRO-INDUSTRIAL WASTES WITH LARGE AMOUNT OF ORGANIC MATERIALS HAVING HIGH COD VALUES AND THE PLENTY OF NITROGEN AND PHOSPHORUS COMPOUNDS. CORN STEEP LIQUOR (CSL) IS ONE OF THE FOOD PROCESSING WASTES CAN CAUSE SECONDARY PROBLEMS IF ACCUMULATE CONSUMEDLY IN ENVIRONMENT. CSL CAN BE USED AS A NATURAL NITROGEN SOURCE FOR PRODUCTION OF BIOLOGICAL COMPOUNDS SUCH AS BIOSURFACTANTS. BIOSURFACTANTS ARE THE MICROBIAL SURFACTANTS PRODUCED BY A VARIETY OF MICROORGANISMS. THEY ARE PROMISING REPLACEMENTS FOR CHEMICAL SURFACTANTS BECAUSE OF BIODEGRADABILITY, NON-TOXICITY AND BEING ABLE TO PRODUCE FROM RENEWABLE SOURCES. IN THIS STUDY CSL WITH COD CONCENTRATION OF 54180 MG/L AND 38.96% TOC WAS USED AS THE NITROGEN SOURCE FOR BIOSURFACTANT PRODUCTION BY PSEUDOMONAS AERUGINOSA. BIOSURFACTANT PRODUCTION YIELD IN THIS PROCESS WAS AROUND 24 G/L. PRODUCED BIOSURFACTANTS SHOWED GOOD SURFACE ACTIVITY, THEY COULD REDUCE THE SURFACE TENSION OF WATER FROM 72 TO 28 MN/M. THEIR EMULSIFICATION ABILITY WAS PRESENTED BY EMULSIFICATION INDEX OF 68% FOR WATER AGAINST KEROSENE. HENCE, THEY HAVE POTENTIAL APPLICABILITIES IN HYDROCARBON REMEDIATION, ENHANCE OIL RECOVERY, COSMETICS, DETERGENTS, FOOD PROCESSING AND OTHERS.
