Structural determination of the O-specific polysaccharide from the Xanthomonas fragariae lipopolysaccharide fraction

The structure of the O-specific polysaccharide from the lipopolysaccharide fraction of the phytopathogenic bacterium Xanthomonas fragariae, the causal agent of the angular leaf spot of strawberry, is described. On the basis of the spectroscopic data, chemical analyses and degradation methods, a structure is suggested.
