title: Re-investigation of the structure of the capsular polysaccharide of Klebsiella K15 using bacteriophage degradation and inverse-detected NMR experiments.
abstract: The structure of the capsular polysaccharide from Klebsiella K15 has been re-investigated, principally by 1D and 2D 1H- and 13C-NMR spectroscopy of the oligosaccharide-alditol obtained by depolymerisation of the polysaccharide with a viral-borne endoglycanase followed by borohydride reduction of the isolated repeating oligosaccharide. The capsular polysaccharide was shown to have the repeating unit: [Formula: see text]
