Structural determination of the exopolysaccharide of Pseudoalteromonas strain HYD 721 isolated from a deep-sea hydrothermal vent.
The structure of the exopolysaccharide produced by Pseudoalteromonas reference strain HYD 721 recovered from a deep-sea hydrothermal vent has been investigated. By means of methylation and beta-elimination analysis, selective degradation of the uronic acids, partial depolymerization and NMR studies, the repeating unit of the polymer was deduced to be a branched octasaccharide with the structure shown.
