Abstract : A new, cost effective media was formulated with soy chunk powder (SCP) as the nutrient source. Growth parameters such as temperature, pH and substrate concentration were optimized. Temperature of 300C, pH of 4 and 1.5% (w/v) of substrate concentration, constitute the optimal condition for the maximal production of the enzyme. The enzyme production peaked in the 5th day of incubation with a maximal enzyme activity of 1.218 U/mg which is 42% as efficient as production in media employing pure substrate. Aspergillus niger isolated from the soil samples collected from the precincts of the campus was employed in the current study.
