he D.O.E. has conducted studies using G. sulfurreducens to reduce uranium contamination in ground water at Rifle Mill mine in Colorado where the United States used to sequester the metal for nuclear weapons production. Also, G. sulfurreducens has shown the potential to destroy petroleum contaminants in polluted groundwater via oxidation into carbon dioxide. Interestingly enough, this bacterium was originally isolate from hydrocarbon contaminated soil sample from Oklahoma. Other applications for G. sulfurreducens have been explored such as electricity production from sewage biomass and also as biosensors given sulfurreducens’ capacity for adaptation.
