A sulfated O-specific polysaccharide containing D-mannose, L-rhamnose, and the sulfate group was obtained by mild acid hydrolysis of lipopolysaccharide (S-form) of the marine bacterium Pseudoalteromonas marinoglutinosa KMM 232. Based on analysis of methylation and 13C-NMR spectroscopy of native and desulfated polysaccharides, the following structure of disaccharide repeat unit in the O-specific polysaccharide has been established: [scheme]. This is the first report of a sulfated O-specific polysaccharide isolated from gram-negative bacteria.

D006088 Gram-Negative Aerobic Bacteria A large group of aerobic bacteria which show up as pink (negative) when treated by the gram-staining method. This is because the cell walls of gram-negative bacteria are low in peptidoglycan and thus have low affinity for violet stain and high affinity for the pink dye safranine.

D019081 O Antigens The lipopolysaccharide-protein somatic antigens, usually from gram-negative bacteria, important in the serological classification of enteric bacilli. The O-specific chains determine the specificity of the O antigens of a given serotype. O antigens are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell.
