To investigate the growth effect of branched oligosaccharides on the principal intestinal microorganisms, Bifdobacterium, Lactobacillus, Clostridium, Escherichia, Eubactemum, Enterucoccus, Staphylococcus and Bacteroides were cultivated on a medium containing branched oligosaccharides and panose. B. adolescentis, B. logum and L. aciduphilus grew effectively on the medium containing panose, while C. pe@igens, C. paraputrificum, Bac. fragilis and S. aurezds did not. The content of panose decreased greatiy in the culture broth of branched oligosaccharides of B, adolescentis, but it remained in the culture of C. perfringens. The results indicated that panose was consumed effectively by B. adolescentis, but not utilized by C. perfringens. 3. adolescentis still grew on the panose remained in the broth of mixed cultivation of B. adolescentis and C. perfn'ngens. Therefore, panose and branched oligosaccharides seem to promote selectively the growth of B. adolescentis in the human intestine.
