The ability of beta-glucosidase from the fungus Geotrichum candidum 3C to degrade cell oligosaccharides, disaccharides and glycosides was examined. It was demonstrated that the rate of enzymic hydrolysis of cell oligosaccharides depended on the length of the substrate chain. The major product was glucose. The beta-glucosidase purified showed high specificity towards beta-glucopyranosyl and degraded only the glucosides which incorporated beta-glucopyranosyl. The enzyme had a relatively low specificity towards aglycon, and hydrolyzed both disaccharides and aryl-glucosides. The enzyme also showed traansglycosylase activity.
研究了白地霉3C真菌的β-葡萄糖苷酶降解纤维寡糖、二糖和糖苷的能力。结果表明，纤维寡糖的酶促水解速率取决于底物链的长度。主要产物是葡萄糖。纯化后的β-葡萄糖苷酶对β-吡喃葡萄糖基具有高度特异性，仅降解含有β-吡喃葡萄糖基的糖苷。该酶对糖苷配基的特异性相对较低，能水解二糖和芳基糖苷。该酶还表现出转糖基酶活性。
