Structure of the O-specific polysaccharides of the lipopolysaccharides of Xanthomonas campestris pv. vignicola GSPB 2795 and GSPB 2796.
The O-specific polysaccharides of Xanthomonas campestris pv. vignicola GSPB 2795 and GSPB 2796 were studied by sugar and methylation analyses, Smith degradation, ID, 2D 1H and 13C NMR spectroscopy. It was found that the polysaccharides are similar branched D-rhamnans lacking strict regularity, and their structures can be described as follows: [carbohydrate equation: see text] where Rha(v) is present in a non-stoichiometric amount, which varies from strain to strain.
