Abstract: Mild acid hydrolysis of the lipopolysaccharide from Yersinia kristensenii strain 103 (0:12.26) afforded teichoic acid-like polysaccharide. From the results of methylation, dephosphorylation, partial Smyth degradation, and ¹³C and ³¹P NMR data the structure of the repeating unit of the polysaccharide was deduced as follows:

→6)-D-Glcp(βl→6)-D-GalNAcp(α1→3)-L-FucNAcp(α1→3)-D-GlcNAcp(α1→2)Gro1P→
          2|                             4|
    D-G1cp α                             D-G1cpa,

The structure was confirmed by complete interpretation of polysaccharide ¹³C NMR spectrum.
