Quercetin was the best inducer for the production of a highly glucose-tolerant, extracellular beta-glucosidase in Aspergillus niger and Aspergillus oryzae. The enzyme was separated from the major and common beta-glucosidase by gel filtration and that from Aspergillus oryzae further purified by ion-e...
