Structure of the exopolysaccharide of Vibrio diabolicus isolated from a deep-sea hydrothermal vent

摘要

The structure of the exopolysaccharide produced under laboratory conditions by Vibrio diabolicus, a bacterium recovered from a deep-sea hydrothermal vent, has been investigated using sugar and methylation analysis and NMR spectroscopy. The polysaccharide consists of a linear tetrasaccharide repeating unit with the following structure. ->3)-#beta#-D-GlcpNAc-(1 -> 4)-#beta#-D-GlcpA-(1 -> 4)-#beta#-D-GlcpA-(1 -> 4)-#delta#-D-D-GalpNAc-(1 ->
