Abstract: | Summary Accumulation of uranium (U) is reported for isolated exopolysaccharide produced by Pseudomonas sp. EPS-5028. A maximum uptake of 96 g U/mg polymer was observed. In contrast, the maximum accumulation of uranium by deacylated polysaccharide was 46 g/mg. This metal-complexing capacity observed suggests that the anionic reactive sites on the structure could be responsible for this activity. Metal uptake was affected by pH and was not affected by temperature. Expolysaccharide from Pseudomonas sp. EPS-5028 obeyed the Freundlich isotherm indicating single layer adsorption.Offprint requests to: F. Congregado |
