Abstrakt: The O-polysaccharide was isolated from the lipopolysaccharide of Cellulophaga algicola and studied by chemical analyses along with 1 H and 13 C NMR spectroscopy, including 2D 1 H, 1 H COSY, TOCSY, ROESY, 1 Н, 13 С HSQC, HMBC experiments. It was found that the polysaccharide is built up of branched pentasaccharide repeating units, containing D-mannose (Man), D-glucuronic acid (GlcA), N-acetyl-D-glucosamine (GlcNAc), two L-rhamnose (Rha) residues and O-acetyl groups in a non-stoichiometric amount and has the following structure.
