摘要：

The structural analysis of a polysaccharide moiety of Pseudomonas xanthomarina KMM 1447(T) lipopolysaccharide (LPS) was carried out. Mild acid degradation of LPS resulted in identification of two polysaccharides. The major one was built of beta-D-GlcpNAcA residues amidated with L-Ala and Gly residues randomly. The minor polysaccharide was composed of branched tetrasaccharide repeating units constituted by two D-Galp, D-GalpNAc and ether of D-Glc with (2R,4R)-2,4-dihydroxypentanoic acid lactone (2R,4R-Dhpl): -> 3)-alpha-D-Galp-(1 -> 3)-beta-D-Galp-(1 -> 3)-[beta-D-Glcp4(2R,4R-Dhpl)-(1 -> 4)]-beta-D-GalpNAc-(1 -> .
