Anstract

Effect of NaOH pretreatment on the biodegradation of corn cobs for the production of cellulase and protein was studied usingAspergillus niger. Delignification of cobs with NaOH remarkaby increased the production of cellulase and protein. Treatment of cobs with 2% NaOH was found to be the best with respect to their susceptibility to biodegradation for maximum production of cellulose 1,4-β-cellobiosidase, cellulase, β-glucosidase soluble protein and crude protein; this also led to the highest protein recovery, maximum cellulose utilization and also for the maximum degradation of substrate.
