Abstract :
An O-polysaccharide and oligosaccharides were isolated by GPC following mild acid degradation of the lipopolysaccharide of Providencia alcalifaciens O28. The O-polysaccharide was studied by sugar and methylation analyses, 1H and 13C NMR spectroscopy, including 2D ROESY and H-detected 1H,13C HSQC and HMBC experiments, and the following structure of the branched pentasaccharide repeating unit was established:
