ABSTRACT129I is of major concern because of its mobility in the environment, excessive inventory, toxicity (it accumulates in the thyroid), and long half-life (∼16 million years). The aim of this study was to determine if bacteria from a129I-contaminated oxic aquifer at the F area of the U.S. Department of Energy's Savannah River Site, SC, could accumulate iodide at environmentally relevant concentrations (0.1 μM I−). Iodide accumulation capability was found in 3 out of 136 aerobic bacterial strains isolated from the F area that were closely related toStreptomyces/Kitasatosporaspp.,Bacillus mycoides, andRalstonia/Cupriavidusspp. Two previously described iodide-accumulating marine strains, aFlexibacter aggregansstrain and anArenibacter troitsensisstrain, accumulated 2 to 50% total iodide (0.1 μM), whereas the F-area strains accumulated just 0.2 to 2.0%. Iodide accumulation by FA-30 was stimulated by the addition of H2O2, was not inhibited by chloride ions (27 mM), did not exhibit substrate saturation kinetics with regard to I−concentration (up to 10 μM I−), and increased at pH values of <6. Overall, the data indicate that I−accumulation likely results from electrophilic substitution of cellular organic molecules. This study demonstrates that readily culturable, aerobic bacteria of the F-area aquifer do not accumulate significant amounts of iodide; however, this mechanism may contribute to the long-term fate and transport of129I and to the biogeochemical cycling of iodine over geologic time.
