The structure of the Butyrivibrio fibrisolvens strain CF3 capsular polysaccharide has been investigated mainly by sugar and methylation analyses, Smith degradation, NMR spectroscopy, and mass spectrometry. The results indicate that the polysaccharide is composed of pentasaccharide repeating units having the following structure: →4)-[β-D-Glcp-(1→2)-]-β-L-Altp-(1→4)-β-D-Glcp-(1→3)-4-O-[(R)-1-carboxyethyl]-β- D-Glcp-(1→4)-6-O-[(R)-1-carboxyethyl]-α-D-Galp-(1→

Bacterial polysaccharide, Butyrivibrio fibrisolvens, (1-carboxyethyl)-galactose, (1-carboxyethyl)-glucose, L-altrose
