Bioremediation of metal contamination

Curr Opin Biotechnol. 1997 Jun;8(3):285-9. doi: 10.1016/s0958-1669(97)80005-5.


Recent studies have demonstrated that microbes might be used to remediate metal contamination by removing metals from contaminated water or waste streams, sequestering metals in soils and sediments or solubilizing metals to aid in their extraction. This is primarily accomplished either by biosorption of metals or enzymatically catalyzed changes in the metal redox state. Bioremediation of metals is still primarily a research problem with little large-scale application of this technology.
