Abstract
An extracellular beta-glucosidase II of Aspergillus niger catalyzed th e synthesis of methyl beta-glucoside and ethyl beta-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 yiel d of methyl beta-glucoside and ethyl beta-glucoside was 83% (mol/mol; 12 mg/ mi) and 53% (mol/mol; 5.5 mg/ml), based on cellobiose consumed.
