Galactosidases Of Strain Bifidobacterium Longum Bim В-813d With Transglycosylating Activity

Abstract

Activity of bifidobacterial culture B. longum BIM В-813D to synthesize α- and β-galactosidases was investigated. Full genome sequencing and biochemical analysis have revealed isoenzymes with α- and β-galactosidase activities capable in addition to hydrolytic action to carry out transglycosylation reactions yielding galactooligosaccharides. The obtained data enable to recommend bifidobacteria B. longum BIM В-813D as a key ingredient of probiotic products.
