Project Abstract
Cr(VI) contamination of groundwater and soils is a primary public health concern in Ireland. Bioremediation is an environmental-friendly salternative for Cr(VI) removal from groundwaterand soils, but Cr(VI) toxicity limits the efficiency of bioremediation. We will use for the first time genome shuffling techniques to improve Cr(VI) tolerance and Cr(VI) reduction capability of the strict anaerobic bacterium Geobacter metallireducens. We will investigate the mechanism of Cr(VI) reduction in the resulting G.metallireducens mutants through an innovative electrochemical approach. Finally, we will test the best performing mutants in a bench-scale Cr(VI) bioremediation process.
