Structure of the exopolysaccharide produced by Enterobacter amnigenus

The bacterial sp. E. amnigenus was isolated from sugar beets harvested in Finland. It produced an exopolysaccharide rich in -fucose, which gave viscous water solns. Its primary structure was detd. Mainly by NMR spectroscopy and ESIMS of oligosaccharides and a polysaccharide with decreased mol. Wt., obtained by Smith degrdn. Of the O-deacetylated native polymer.
