title: Structure of the O-polysaccharide from the lipopolysaccharide of Hafnia alvei strain PCM 1546.
abstract: An acidic O-polysaccharide isolated by mild acid hydrolysis from the lipopolysaccharide of Hafnia alvei PCM 1546 is composed of D-Gal, D-Glc, D-GlcA, D-GalNAc and O-acetyl groups in the ratios 1:1:1:2:1.6. On the basis of sugar and methylation analyses along with 1D and 2D 1H and 13C NMR spectroscopy, the following structure of the pentasaccharide repeating unit of the polysaccharide was established: [see equation in text].
