Utilizing sugar, methylation, and absolute configurations analyses as well as NMR spectroscopy, the chemical repeating unit of the O-specific polysaccharide of Pectobacteriumversatile CFBP6051T was identified as: The polymer contains residues of an unusual, higher-branched monosaccharide, named erwiniose (3,6,8-trideoxy-4-C-(R-1-hydroxyethyl)-d-gulo-octose). Comparison of the P. versatile CFBP6051T O-polysaccharide with those isolated from strains of other Pectobacterium species indicated high differentiation in their structures within this genus.
