O-polysaccharides of phytopathogenic bacteria Xanthomonas campestris were isolated by mild acid degradation of the lipopolysaccharides and studied by sugar and methylation analysis, along with 1H and 13C NMR spectroscopy. The following structures of the repeating units of the polysaccharides of X. campestris pv. phaseoli var. fuscans GSPB 271 (1). and X. campestris pv. malvacearum GSPB 1386 and GSPB 2388 (2). were established:The O-polysaccharides of X. campestris are structurally similar to those of some Pseudomonas syringae strains.
通过对脂多糖进行温和酸降解，分离出了植物病原菌野油菜黄单胞菌的O-多糖，并通过糖分析、甲基化分析以及1H和13C核磁共振光谱对其进行了研究。确定了野油菜黄单胞菌菜豆致病变种fuscans GSPB 271（1）以及野油菜黄单胞菌锦葵致病变种GSPB 1386和GSPB 2388（2）多糖重复单元的以下结构：野油菜黄单胞菌的O-多糖在结构上与一些丁香假单胞菌菌株的O-多糖相似。
