Abstract
Preparation of 4-hydroxybutyl-beta-D-glucoside was achieved by reverse d hydrolysis from glucose using almond-beta-glucosidase impregnated on mineral supports, while 4-hydroxybutyl-alpha-D-glucoside was obtained from glucose or by one-pot starch hydrolysis followed by glucosidatio n catalysed by gamma-amylase (amyloglucosidase) from Rhizopus mold on celites. The influence of the support nature and of water activity wer e investigated in order to shift the equilibrium towards glycosidation . (C) 1997 Elsevier Science Ltd.
