Biotechnology Letters Aims and scope Submit manuscript

Abstract

The maximum yield of β-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 β-glucosidase was at 60–70 °C and pH 4.8.
