Abstract

The structure of О-polysaccharide (О-antigen) of Escherichia coli O95 was established using the analysis of deacylated lipopolysaccharide of E. coli O95 by 2D 1H and 13С NMR spectroscopy. It was found to consist of disaccharide repeating units containing one of each 3-substituted residues of d-fucose and d-threo-pent-2-ulose (xylulose).
