Structure of the O-polysaccharide from the lipopolysaccharide of Providencia alcalifaciens O33
Copyright policy )Structure of the O-polysaccharide from the lipopolysaccharide of Providencia alcalifaciens O33
Mild acid degradation of the lipopolysaccharide from Providencia alcalifaciens O33 resulted in an O-polysaccharide along with core and O-unit-bearing core oligosaccharides. Composition of the oligosaccharides was inferred by ESI mass spectrometry. Based on sugar and methylation analyses, Smith degradation and (1)H and (13)C NMR spectroscopy data, the following structure of the tetrasaccharide O-unit of the O-polysaccharide was established: Another O-polysaccharide structure has been reported earlier for Providencia stuartii О33 but later found to belong to a P. stuartii О52 strain.
