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.
通过对海洋细菌嗜海栖假交替单胞菌KMM 232脂多糖（S型）进行温和酸水解，获得了一种含有D-甘露糖、L-鼠李糖和硫酸基团的硫酸化O-特异性多糖。基于对天然多糖和去硫酸化多糖的甲基化分析及13C-NMR光谱分析，确定了O-特异性多糖中二糖重复单元的以下结构：[结构图]。这是首次报道从革兰氏阴性菌中分离出的硫酸化O-特异性多糖。
