β¦ Synopsis
Capsular polysaccharide (CPS) was obtained by water-saline extraction of the Alteromonas sp. CMM 155. On the basis of solvolysis with anhydrous HF and 1H-and 13C-NMR spectral data, including NOE experiments, it was concluded that the capsular polysaccharide had the following structure containing novel N-acyl-amino sugar and bacillosamine residues:

The capsular polysaccharide from Streptococcus pneumoniae Type 23 (S-23) was found to contain D-galactose, D-glucose, L-rhamnose, glycerol, and phosphorus in the ratios of 1: 1: 2:0.6: 1. Methylation analysis provided information about the linkages of the different sugar units. The sequence of the d
The capsular polysaccharide of A. pleuropneumoniae serotype 10 was found to be composed of a linear disaccharide repeating unit. By use of methylation analysis, partial hydrolysis, g.l.c.--and f.a.b.- m.s., and 1D and 2D n.m.r. studies, the polysaccharide was determined to be a polymer of a repeatin
The structure of the capsular polysaccharide elaborated by KlebsieUa type 7 has been investigated. NMR spectroscopy together with sugar and methylation analysis have been the main methods used. A uronic acid degradation was also employed. The polysaccharide consists of hexasaccharide repeating units
## Abstract The capsular polysaccharide from __Acinetobacter lwoffii__ F78 was isolated and purified, and its structure was elucidated by chemical analyses, NMR spectroscopy, and mass spectrometry. The presence of a capsule on this bacterium was confirmed by transmission electron microscopy experim
