The structure of the O-specific polysaccharide of the lipopolysaccharide from Burkholderia gladioli pv. agaricicola.
A neutral O-specific polysaccharide containing d-mannose, d-rhamnose and d-galactose was obtained by mild acid hydrolysis of the lipopolysaccharide of the plant pathogenic bacterium Burkholderia gladioli pv. agaricicola. By means of compositional analyses and NMR spectroscopy, the chemical repeating unit of the polymer was identified as a linear trisaccharide of the structure shown below, in which the mannose residue was quantitatively acetylated at C-2.
