Lipopolysaccharide was obtained from the aerobic moderately halophilic bacterium Halomonas fontilapidosi KR26. The O-polysaccharide was isolated by mild acid degradation of the lipopolysaccharide and was examined by chemical methods and by H and C NMR spectroscopy, including H,H COSY, TOCSY, ROESY, and H,C HSQC, and HMBC experiments. The following structure of the linear tetrasaccharide repeating unit was deduced. →2)-α-l-Rhap-(1→2)-α-l-Rhap-(1→3)-α-l-Rhap-(1→3)-β-d-Galp-(1→.
脂多糖从需氧中度嗜盐细菌盐单胞菌 KR26 中提取。O-多糖通过脂多糖的温和酸降解分离，并通过化学方法和 H 和 C NMR 光谱学，包括 H,H COSY、TOCSY、ROESY 和 H,C HSQC 和 HMBC 实验进行检查。推断出该线性四糖重复单元的如下结构：→2)-α-l-Rhap-(1→2)-α-l-Rhap-(1→3)-α-l-Rhap-(1→3)-β-d-Galp-(1→。
