The O-specific polysaccharide obtained by mild-acid degradation of Aeromonas bestiarum 207 lipopolysaccharide was studied by sugar and methylation analyses along with (1)H and (13)C NMR spectroscopy. The sequence of the sugar residues was determined by ROESY and HMBC experiments. It is concluded that the O-polysaccharide is composed of branched pentasaccharide repeating units of the following structure: [structure: see the text]
