Chemical analysis was carried out on lipopolysaccharides from Vibrio cholerae bio-serogroup Hakata 487-85. The O-specific chain of the phenol-soluble lipopolysaccharides was demonstrated by 13C-NMR spectroscopy and methylation analysis to contain a linear homopolymer of alpha(1----2) linked N-acetylperosamine (4-acetamido-4,6-dideoxy-D-mannopyranose), which was closely similar to but not identical to a linear alpha(1----2) linked N-3-deoxy-L-glycerotetronyl (S-2,4-dihydroxybutyryl) perosamine-homopolymer constituting that of O1 Vibrio cholerae lipopolysaccharides.
对霍乱弧菌生物血清群博多487 - 85的脂多糖进行了化学分析。通过13C - NMR光谱和甲基化分析表明，酚溶性脂多糖的O - 特异性链含有α(1→2)连接的N - 乙酰过氧胺（4 - 乙酰氨基 - 4,6 - 二脱氧 - D - 甘露吡喃糖）的线性均聚物，它与构成O1群霍乱弧菌脂多糖的α(1→2)连接的N - 3 - 脱氧 - L - 甘油四糖基（S - 2,4 - 二羟基丁酰基）过氧胺线性均聚物非常相似，但并不相同。
