Abstract

Laboratory experiments with mixed populations of sulfate -reducing bacteria were shown to mediate the removal of milligrams/liter concentrations of uranium, selenium, arsenic and vanadium from aqueous solution via reduction, precipitation and adsorption. Results of laboratory experiments with active sulfidogenic biomass suggest that injection of sulfate and a source of carbon could enhance natural anaerobic microbial activity in and around uranium leach mines leading to in situ immobilization of contaminating metals.
