Abstract
Wild strainof Aspergillus terreus is very good producer of /gb-glucosidase. It produces 15 nkat/mL (0.9 IU/mL) of extracellular β-glucosidase at pH 5.0. The medium pH level strongly affects the production and binding of β-glucosidase on the cells and on residual cellulose. At pH 4.0 the rate of enzyme synthesis and the level of total activity is highest but 60—75 % of this activity is bound. At higher pH levels the enzyme is mainly released to the medium.Keywords
