Abstract

The O-polysaccharide was isolated from the lipopolysaccharide of Litorimonas taeanensis G5T and studied by chemical methods along with 1H and 13C NMR spectroscopy, including 1H, 1H COSY, 1D and 2D TOCSY, NOESY, 1H, 13C HSQC, HMBC, and H2BC experiments. The following new structure of the O-polysaccharide of L. taeanensis G5T containing 2-acetamido-2-deoxy-d-galacturonic acid (d-GalNAcA), 2-acetamido-4-((3S,5S)-3,5-dihydroxyhexanamido)-2,4-dideoxy-d-quinovose (d-QuiNAc4NR), and 2-acetamido-2,6-dideoxy-l-xylo-hexos-4-ulose (l-Sug) was established: [Display omitted] where R is (3S,5S)-3,5-dihydroxyhexanoic acid.
