✦ Synopsis

Sugar and methylation analysis with the use of gas chromatography+mass spectrometry and lit NMR spectroscopy proved that the core oligosaccharides isolated from lipopolysaccharides of eight Hajhia alvei strains have the identical hexasaccharide skeleton. However, tH,3tP heterocorrelatcd spectra showed that the phosphorylation pattern is not the same. The branched heptose for the ATCC 13337, 1187, 2, 1191, 1196, 1220, and 481L strains is pbosphorylated as in the following formula, where P =-O-P(O) (O-)2 and P-PEtN--[-O-P(O) (O-) ] 2--.O(CH,,) 2NH~
