Ultraviolet light on Escherichia coli fuses with Green Fluorescence Protein to study the localization of proteins in living cells. Through the use of GFP, promoters/genes are localized which specific toxic metals require to aid in reduction of metals and radionuclides.

Background: Bacterial iron reduction is a fundamental biogeochemical process in soils, sediments, surface and groundwaters. Shewanella putrefaciens are metal reducers. By using these organism they can oxidize organic matter with Fe (III) , polyvalent metals including U, Tc, Cr, and Pu as electron acceptors changing their valence. Through the use of GFP (green fluorescent protein) we can localize which promoters/genes respire specific toxic metals to help aid in reduction of metals and radionuclides in the Hanford Site.
