Aspγgillus niger에 의한 $eta$-lucosidase의 최적 생산조건으로는 0.8% CMC, 0.5% bef extract, 0.3% $Ca(N0_3)_2, 0.03% K_2HPO_4, 0.03% FeSO_4, 0.05% Li_2SO_4, 0.2% tween 80,$ trace solution lml, 초기 pH 4.0, 배양온도 $30^{circ}C$, 배양기간 5-6일이었고, 그 배양액 중의 최종 효소 활성은 8.5-9.8unit/ml였다.
This study was designed to reveal the conditions for $eta$-glucosidase production from Aspergillus niger. The maximal enzyme production was obtained when the fungus was cultured at $30^{circ}C$ 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.
