Abstract :
An acidic polysaccharide was isolated from Pseudoalteromonas flavipulchra type strain NCIMB 2033T and found to consist of 6-deoxy-l-talose (l-6dTal), d-galactose and 3-deoxy-d-manno-oct-2-ulosonic acid (Kdo). The identities of the monosaccharides were ascertained by sugar analysis and 1D 1H and 13C NMR spectroscopy in conjunction with 2D COSY, TOCSY, ROESY and 1H, 13C HMQC experiments, which enabled determination of the following structure of the trisaccharide repeating unit of the polysaccharide:→3)-α-l-6dTalp4Ac-(1→3)-β-d-Galp-(1→7)-α-Kdop-(2→
