✦ Synopsis

The capsule of Bacteroides fragilis (ATCC23745) consists of two distinct polysaccharides, the separation of which could not be accomplished. The mouse-passaged strain (23745M1), however, yielded a preponderant polysaccharide which was isolated and purified. Using mainly high resolution NMR spectroscopy, the structure of the polysaccharide was elucidated and it is composed of the following repeating unit: [formula see text]

Structural analysis of the specific capsular polysaccharide produced by Rhodococcus equi serotype 7 indicated it to be a high-molecular-weight polymer consisting of equal molar amounts of D-galactose, D-mannose, L-rhamnose, and pyruvic acid. By employing a combination of chemical and NMR techniques,

The primary structure of the acidic capsular antigen produced by E. coli K84 was shown by glycose and methylation analysis, and by 1D and 2D 1H and 13C NMR studies of the polysaccharide and an oligosaccharide produced by lithium-ethylenediamine degradation of the polysaccharide, to be comprised of l

The structure of the capsular polysaccharide from the Klebsiella K8 reference strain 1015 has been elucidated. The structure was deduced from sugar analysis, different methylation analyses, a uronic acid degradation, and NMR spectroscopy. It is concluded that the polysaccharide is composed of pentas

Although some Lactobacilfus strains are reported to produce extracellular poly-saccharidesi4, nothing is known of their structure. We recently isolated a capsular polysaccharide-producing Lactobacillus kejiranofaciens from kefir grain?'. The polysaccharide extracted from kefir grains was named kefir
