In our previous study, the numbers of bifidobacteria in the human intestine were significantly increased by administration of palatinose condensates (PC). In the present study, we investigated the utilization of palatinose, PC, trehalulose and isomalt by various intestinal bacteria in vitro. Palatinose was utilized by all Bifidobacterium spp., except for B. bifidum, and also by some other intestinal bacteria. The utilization pattern for trehalulose was very similar to that for palatinose. Isomalt, as well as other sugar alcohols, was difficult to utilized by intestinal bacteria. PC were utilized by Bifidobacterium spp., but PC utillization by other strains of other genera was absent or weak. This study shows that PC are utilized only by Bifidobacterium spp., thus explaining the significant increase of only bifidobacteria caused by PC in the human intestine in our previous study.
