Synthesis of alkyl [beta]-glucosides from cellobiose with Aspergillus niger [beta]-glucosidase II

Synthesis of alkyl [beta]-glucosides from cellobiose with Aspergillus niger [beta]-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 e...

Zusammenfassung: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/mol; 5.5 mg/ml), based on cellobiose consumed. © Rapid Science Ltd. 1998[PUBLICATION ABSTRACT]
