Over-production of beta-glucosidase by Aspergillus niger mutant from lignocellulosic biomass

The maximum yield of beta-glucosidase by A. niger KK2 mutant, grown on the basal medium for 7 days, was 514 I U g(-1) ground rice straw, and was about twice those obtained from wheat straw or bran by previous researchers. Optimal activity of beta-glucosidase was at 60-70 degrees C and pH 4.8.
