Abstract: | The structure of Xanthomonas campestris pv. vitians O-specific polysaccharide of the lipopolysaccharide fraction, extracted from the aqueous phase, was defined, on the basis of chemical and spectroscopical methods, as constituted by the following repeating unit: --> 3)-alpha-L-Rhap-(1 -->]n 3)-beta-L-Rhap-(1 --> where n is more frequently equal to 2, but it also assumes values equal to 1 and to 3. |
