Aims: To determine whether alternansucrase (ASR)‐derived oligosaccharides can support the in vitro growth of various intestinal bacteria. Methods and Results: Growth was assessed from each culture after incubation in a medium containing ASR‐derived oligosaccharide as sole carbohydrate source. Most of the Bifidobacterium spp. tested showed growth on all five of the oligosaccharides tested while the Lactobacillus spp., Bacteroides thetaiotaomicron , coliforms and pathogenic bacteria displayed no or little growth. Conclusions: The ASR‐derived oligosaccharides were selectively utilized by many of the Bifidobacterium spp. tested but did not support significant growth of the Lactobacillus spp., Bact. thetaiotaomicron , coliforms and pathogenic bacteria tested. Significance and Impact of the Study: Alternansucrase‐derived oligosaccharides are a potential source of new prebiotics.
