Structure of the O-polysaccharide from the moderately halophilic bacterium Halomonas fontilapidosi KR26

Carbohydr Res. 2023 Dec 30;536:109019. doi: 10.1016/j.carres.2023.109019. Online ahead of print.ABSTRACTLipopolysaccharide 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 1H and 13C NMR spectroscopy, including 1H,1H COSY, TOCSY, ROESY, and 1H,13C 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→.PMID:38211449 | DOI:10.1016/j.carres.2023.109019
