• An Enterobacter sp. capable of effecientyl producing an acidic exopolysaccharide was recently isolated. The bacterium was cultivated in a synthetic medium for production of a homogeneous polysacchardie. The polysaccharide isolated by anion exhange chromatography gave a peak on gel filtration in the presence of 1 M NaCl. The concentration of the polysaccharide in the medium was maximum on the third day of cultivation, by which time 13.5% (w/w) of the sucrose which had been supplied as the sole carbon source was converted to the polysacchardie. The polysaccharide consists of glucose, mannose, rhamnose, fucose, galacturonic acid and glucuronic acid, and was concluded to be an acidic exopolysaccharide with novel chemical properties on the basis of its monomeric sugar composition. A rheological comparision of the polysacchardie with xanthan gum revelated they are rheologically similar but that the former is stiffer than the latter. In addition, strong gelation of the polysaccharide with Cu<2+> suggests that the polysaccharide would be useful for copper removal from wastewater.
