Transglucosidation in Penicillium chrysogenum Q-176. Isolation and identification of the oligosaccharides

Abstract
A transglucosidase from Penicillium chrysogenum Q-176 catalyses the conversion of maltose into glucose and oligosaccharides. Charcoal chromatography of the oligosaccharide mixture resulted in the separation of 4 components, identified as isomaltose, isomaltotriose, panose and 4-[alpha]-isomaltotriosyl-D-glucose, and a group of higher oligosaccharides, of which isomalto-tetraose, 4-[alpha]-isomaltotetraosyl - and 4-[alpha]-isomaltopentaosyl-D-glucoses are possible constituents.
