•Lipopolysaccharide of Providencia alcalifaciens O45:H25 was degraded with mild acid.•Structure of the O-polysaccharide obtained was established by chemical and NMR methods.•The O-polysaccharide was found to be in agreement with the O-antigen gene cluster.
O-Polysaccharide was obtained by mild acid degradation of the lipopolysaccharide of Providencia alcalifaciens O45:H25 and studied by sugar analysis, Smith degradation, and 1H and 13C NMR spectroscopy. The following structure of the pentasaccharide repeat of the O-polysaccharide was established:Figure optionsDownload full-size imageDownload as PowerPoint slideThe O-antigen gene cluster of P. alcalifaciens O45 was sequenced and found to be in full agreement with the O-polysaccharide structure established.
