【Abstract】 The biological function of bifidobacteria growth factor, galactooligosaccride were presented. Investigation of β-galactosidase action on lactose and the products of its hydrolysis had brought much insight into the reaction mechanism. Four models were used to provide qualitative information on the reaction. Its current research situation and prospects were also covered briefly.更多还原
