The O-specific polysaccharide was isolated from the lipopolysaccharide of type strain Idiomarina abyssalis КММ 227(T) and studied by sugar analysis, Smith degradation, and two-dimensional (1)H and (13)C NMR spectroscopy including (1)H,(1)H-TOCSY, (1)H,(1)H-COSY, (1)H,(1)H-ROESY, (1)H,(13)C-HSQC, (1)H,(13)C-HMBC, (1)H,(13)C-H2BC and (1)H,(13)C-HSQC-TOCSY experiments. The new structure of the O-specific polysaccharide of I. abyssalis КММ 227(T) containing 2-O-sulfate-3-N-(4-hydroxybutanoyl)-3,6-dideoxy-d-glucose was established.
