Degraded products of laminaran by the action of Clostridium ramosum were surveyed for their constituent mono-, di-, and trisaccharides by active carbon column chromatography. Trisac-charide was detected in 2% laminaran-containing GAM broth culture which was incubated with Cl. ramosum for 12h. Mono- and disaccharides were detected in 24h culture. Among 11 strains of authentic intestinal bacteria which cannot ferment laminaran, 7 and 8 strains utilized the former and latter products, respectively. Particularly, the growth of lactic acid- or acetic acid-forming bacteria such as Bifidobacterium bifidum and Peptostreptococcus productus was promoted by these degraded products. These results are considered to give experimental support to the suggestion that Bifidobacterium could grow in rats and human intestines when dietary fiber has been ingested.
