Synthesis of alkyl β-glucosides from cellobiose with Aspergillus niger β-glucosidase II

An extracellular β-glucosidase II of Aspergillus niger catalyzed the synthesis of methyl β-glucoside and ethyl β-glucoside with 5.0% (v/v) cellobiose as glucosyl donor in a biphasic media containing 20% (v/v) methanol and 30% (v/v) ethanol, respectively. The maximum yield of methyl β-glucoside and ethyl β-glucoside was 83% (mol/mol; 12 mg/ ml) and 53% (mol… CONTINUE READING
