摘要
研究了肠道细菌对4-β-半乳糖-0-β- d -半乳糖-(1→4)-0-β- d -半乳糖-(1→4)- d -葡萄糖吡喃糖的利用。双歧杆菌能被所有种类的双歧杆菌吸收，而大肠杆菌和几乎所有种类的梭状芽孢杆菌不能吸收。4-β-半乳糖的促生长作用是双歧杆菌所特有的，双歧杆菌被归类为有益肠道细菌。
Utilization of 4-β-Galactosyl-Lactose by the Intestinal Bacteria
Utilization of the 4-β-galactosyl-lactose, O-β-D-galactopyranosyl-(1→4)-0-β-D-galactopyranosyl-(1→4)-D-glucopyranose, by the intestinal bacteria was investigated. The saccharide was utilized by all species of Bifidobacterium, whereas it was not assimilated by Escherichia coli and almost all species of Clostridium tested. The growth-promoting effect of the 4-β-galactosyl-lactose was specific for bifidobacteria being classified as beneficial intestinal bacteria.
