Lesson plan
Geobacter
Geobacter is a genus of bacteria. Geobacter species use anaerobic respiration to alter the redox state of minerals and many pollutants, a trait that makes them useful in bioremediation. Geobacter was the first organism described with the ability to completely oxidize organic compounds to carbon dioxide, and transfer these electrons to metals such as Fe(III), Mn(IV), and U(VI). Geobacter species are also found to be able to transfer electrons to conductive surfaces such as graphite electrodes. They are found in anaerobic habitats including wetlands, subsurface aquifers, soils, and aquatic sediment.
