Extracellular beta -glucosidases from Aspergillus oryzae (two strains), Fusarium oxysporum, Aspergillus terreus and Talaromyces flavus were either induced by cellobiose or 6-deoxyglucose, or produced without induction, i.e., either on casein acid hydrolyzate or on the Sabouraud medium. They were tested to catalyze a stereoselective synthesis of the cis- and trans-isomers of 2-(4-methoxybenzyl)-1-cyclohexyl beta -D-glucopyranosides with either D-glucose or phenyl beta -D-glucopyranoside as sources of the glucosyl unit. The enzymes also hydrolyzed (resolved) diastereoisomeric mixtures of alkyl beta -D-glucopyranosides, which were prepared by the Koenigs-Knorr method from the respective cis- and trans-isomers of 2-(4-methoxybenzyl)-1-cyclohexanol.
