要旨:
The structure of the O-specific polysaccharides of the lipopolysaccharides produced by Hafnia alvei strains ATCC 13337 and 1187 was reinvestigated. The position of phosphate group in the repeating units of the polysaccharides was established with the aid of 1H detected, 31P edited NMR spectra. According to the results obtained, the polysaccharides are teichoic acid-like polymers with the repeating units of the following structure: [formula: see text] where Acyl = D-3-hydroxylbutyryl, and 3-O-acetylation was approximately 30%.
