摘要:
Two types of neutral O-polysaccharides were obtained by mild acid degradation of the lipopolysaccharide isolated by phenol-water extraction from the asymbiotic diazotrophic rhizobacterium Azospirillum brasilense Jm6B2. The following structure of the major O-polysaccharide was established by composition and methylation (ethylation) analyses, Smith degradation, and 1D and 2D H-1 and C-13 NMR spectroscopy: [GRAPHICS] where a non-stoichiometric (similar to 60%) 3-O-methylation of D-rhamnose is indicated by italics.
