Abstract :
The lipopolysaccharide of Citrobacter freundii O22 (strain PCM 1555) was degraded under mild acidic conditions and the O-polysaccharide released was isolated by gel chromatography. Sugar and methylation analyses along with 1H and 13C NMR spectroscopy, including two-dimensional 1H,1H ROESY and 1H,13C HMBC experiments, showed that the repeating unit of the O-polysaccharide has the following structure:
