An acidic O-specific polysaccharide was isolated from Hafnia alvei PCM 1196
lipopolysaccharide and studied by sugar and methylation analyses along wit
h one- and two-dimensional H-1 and C-13 NMR spectroscopy, including NOESY a
nd HMBC experiments. The following structure of the pentasaccharide repeati
ng unit was established:
--> 4)-alpha -D-GalpA-(1 --> 3)-beta -D-GlcpNAc-(1 --> 2)-beta -D-Galp-(1 -
-> 6)-alpha -D-Glcp-(1 --> 6)-alpha -D-GlcpNAc-(1 -->
