title: Structure of the O-specific polysaccharide from the lipopolysaccharide of Citrobacter gillenii O11, strain PCM 1540.
abstract: The O-specific polysaccharide of the lipopolysaccharide of Citrobacter gillenii PCM 1540 (serogroup O11) consists of D-Glc, D-Man, D-GalNAc, D-GlcNAc, 2-acetamido-2,6-dideoxy-D-galactose (D-FucNAc) and O-acetyl groups in the ratios 2:1:1:1:1:1. On the basis of sugar and methylation analyses and Smith-degradation along with 1D and 2D 1H and 13C NMR spectroscopy, the following structure of the branched hexasaccharide repeating unit was established: [structure: see text]. Citrobacter werkmanii PCM 1541 belonging to the same serogroup O11 was found to have an R-form lipopolysaccharide devoid of the O-specific polysaccharide.
