[Antigenic polysaccharides of bacteria. 34. Structure of O-specific polysaccharide chains of lipopolysaccharides from Pseudomonas cepacia strains IMV 4207 (Serotype A) and IMV 598/2].
On the basis of non-destructive analysis by means of 1H and 13C NMR spectroscopy and calculation of specific optical rotation, it was concluded that O-specific polysaccharide of Pseudomonas cepacia strain IMV 4207 (serotype A) has the structure (I): (formula; see text) Two structurally different polysaccharides were found in the ratio of approximately 2.5:1 in P. cepacia strain IMV 598/2 which is serologically related to serotype A in Nakamura classification and serotype 2 in Heidt classification. The minor polysaccharide has the structure (I) whereas the major one possesses the structure (II) which is characteristic of the formerly studied O-specific polysaccharide of P. cepacia strain IMV 4137 belonging to serotype 2: ----4)-beta-D-Galp-(1----2)-alpha-L-Rhap-(1----.
