Heavy metal contamination of subsurface soils, groundwater and surface water is a global problem in water supplies and related ecosystem health. The Department of Energy (DOE) has long been a proponent in finding viable bioremediation solutions. In pursuit of this effort, scientists from the DOE's EMSL, South Dakota School of Mines and Technology and other universities conducted investigations of lead inhibition and detoxification in a model sulfate-reducing bacterium (SRB), D. desulfuricans G20, to improve understanding of the effects of heavy metals on SRB in the presence of soil minerals (goethite and quartz) and develop effective in situ or ex situ bioremediation technologies.
