The regioselectivity of beta-galactosidase derived from Bacillus circulans ATCC 31382 (beta-1,3-galactosidase) in transgalactosylation reactions using D-mannose as an acceptor was investigated. This D-mannose associated regioselectivity was found to be different from reactions using either GlcNAc or GalNAc as acceptors, not

A practical purification method for a non-digestible disaccharide, epilactose (4-O-beta-galactosyl-D-mannose), was established. Epilactose was synthesized from lactose with cellobiose 2-epimerase and purified by the following procedure: (i) removal of lactose by crystallization, (ii) hydrolysis of lactose by beta-galactosidase, (iii) digestion

Epilactose (4-O-beta-galactopyranosyl-D-mannnose) is a rare disaccharide in cow milk that can be synthesized from lactose by the cellobiose 2-epimerase of Ruminococcus albus. In this study, we examined the biological activities of epilactose using male Wistar-ST rats. The apparent rates of

Cellobiose 2-epimerase (CE) efficiently forms epilactose which has several beneficial biological functions. A thermostable CE from Rhodothermus marinus was immobilized on Duolite A568 and packed into a column. Lactose (100 g/L) was supplied to the reactor, kept at 50 °C

We recently reported that cellobiose 2-epimerase from Ruminococcus albus effectively converted lactose to epilactose. In this study, we examined the biological effects of epilactose on intestinal microbiota, bile acid metabolism, and postadministrative plasma glucose by animal tests. Dietary supplementation with
