Abstract

The structure of the O-specific side chain of the lipopolysaccharide from the Gram-negative psychrophilic bacterium Moritella viscosa strain M2-226, responsible for the winter ulcer in Atlantic salmon, has been determined. Monosaccharide analysis and H-1 and C-13 NMR spectroscopy were employed to elucidate the structure. It was concluded that the polysaccharide is composed of a trisaccharide repeating unit with the following structure:)-> 3-beta-D-GlcpNAc-(1 -> 4)-[alpha-D-GlcpA-(1 -> 3)]-alpha-L-Fucp-(1 -> (C) 2011 Elsevier Ltd.
