  Formation of oligosaccharides from lactitol by Aspergillus oryzae β-d-galactosidase

  摘要：

  Six oligosaccharides were first formed from lactitol by a transgalactosylation reaction catalyzed by Aspergillus oryzae beta-D-galactosidase. From the results of methylation analysis, MS, and H-1- and C-13-NMR studies, it was concluded that these oligosaccharides are O-beta-D-galactopyranosyl-(1 --> 4)-O-beta-D-galactopyranosyl-(1 --> 4)-D-glucitol, O-beta-D-galactopyranosyl-(1 --> 3)-O-beta-D-galactopyranosyl-(1 --> 4)-D-glucitol, O-beta-D-galactopyranosyl-(1 --> 4)-O-beta-D-galactopyranosyl-(1 --> 6)-D-glucitol, O-beta-D-galactopyyranosyl-(1 --> 6)-O-beta-D-galactopyranosyl-(1 --> 6)-D-glucitol, O-beta-D-galactopyranosyl-(1 --> 6)-O-beta-D-galactopyranosyl-(1 --> 4)-D-glucitol, O-beta-D-galactopyranosyl-(1 --> 4) and [O-beta-D-galactopyranosyl-(1 --> 5)]-D-glucitol, and O-beta-D-galactopyranosyl-(1 --> 4)-[O-beta-D-galactopyranosyl-(1 --> 1)]-D-glucitol. The last three are newly observed oligosaccharides.
