This study was designed to reveal the conditions for B-glucosidase production from Aspergillus niger. The maximal enzyme production was obtained when the fungus was cultured at 30℃ for 5~6 days in the optimal medium containing 0.8% CMC, 0.5% beef extract, 0.3% Ca(NO3)2, 0.03% K2HPO4, 0.03% FeSO4, 0.05% Li2SO4, 0.2% tween 80, trace solution 1.0ml and initial pH 4.0, and then final enzyme activity under above conditions was 8.5-9.8 unit/ml culture filtrate.
