GALACTOSIDASES OF STRAIN <i>BIFIDOBACTERIUM LONGUM</i> BIM В-813D WITH TRANSGLYCOSYLATING ACTIVITY
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.
