title: 3-Deoxy-octulosonic acid-containing trisaccharide fragment of an unusual core type of some Hafnia alvei lipopolysaccharides.
abstract: The 3-deoxy-octulosonic acid-containing trisaccharide was isolated from the carbohydrate material obtained after the acid hydrolysis of lipopolysaccharides of Hafnia alvei strains 2 and 1211 using gel filtration. For purification the trisaccharide fraction was rechromatographed on a Bio-Gel P2 column. On the basis of sugar and methylation analyses and 1H NMR spectroscopy the trisaccharide was identified as 3-deoxy-7-O-(6-O-acetyl-alpha-D-galactopyranosyl)-4-O-(alpha-L-glycero-D - mannoheptopyranosyl)-D-manno-2-octulopyranosic acid. The occurrence of such bifurcate Kdo-containing structure has not been previously reported in Enterobacteriaceae.
