NMR 0-Specific polysaccharide chains of lipopolysaccharides of a number of serotypes of an enterobacterium, Citrobacter freundii, have been structurally elucidated [l-3]. We now report the structure of a new 0-specific polysaccharide isolated from C. jkuzdii 028,lc.
The structure of Citrobacter O23-specific polysaccharide has been shown by sugar and methylation analyses of the native and chemically degraded polysaccharide and by 1H- and 13C-n.m.r. spectroscopy to consist of the tetrasaccharide repeating-units: ----4)-alpha-D-Man-(1----2)-alpha-D-Man-(1----2)-be
