[Antigenic bacterial polysaccharides. 36. A study of the structure of the O-specific polysaccharide chain of the lipopolysaccharide of Pseudomonas fluorescens IMV 2763 (biostrain G)].
Chemical and serological characterization of the Pseudomonas fluorescens IMV 2763 (biovar G) lipopolysaccharide was carried out. The O-specific polysaccharide chain of the lipopolysaccharide is composed of D-mannose, 6-deoxy-L-talose, N-acetyl-D-galactosamine and O-acetyl groups in the ratio of approximately 2:1:1:1. The polysaccharide is branched and a half of residues of 6-deoxytalose and monosubstituted mannose carry O-acetyl groups. On the basis of methylation, partial acid hydrolysis and 13C NMR analysis it was concluded that the repeating unit of the polysaccharide has the following structure: (formula; see text)
