A novel strain of Bifidobacterium bifidum NCIMB 41171, isolated from a faecal sample from a healthy human volunteer and able to express β-galactosidase activity, was used in synthesis reactions for the production of galactooligosaccharide from lactose. The β-galactosidase activity of whole bifidobacterial cells showed an optimum activity at pH 6.8–7.0 and 40°C. The transgalactosylation activity of the B. bifidum cells from 50% (w/w) lactose resulted in a galactooligosaccharide mixture (20% w/w… CONTINUE READING
