摘要：Streptococcus thermophilus , Lactobacillus delbrueckii subsp. bulgaricus and Bifidobacterium animalis strains were tested for á-galactosidase, â-galactosidase and á-glucosidase activities. Commercially available yoghurts with bifidobacteria were also tested. While bifidobacteria produced all the enzymes mentioned above, lactobacilli and streptococci exhibited only â-galactosidase activity. In yoghurts, only â-galactosidase was detected, while practically no á-galactosidase, and in one product only little á-glucosidase activities were exhibited. It could be concluded that the consumption of bifidobacteria via yoghurt has probably no substantial effect on the digestion of saccharides in the gut.
