Geobacter metallireducens is a Gram negative rod shaped anaerobe which derive energy using iron oxide (rust) as a final electron acceptor, leaving behind iron; Geobacter species may be responsible for large deposits of magnetite. *expand*

They are of interest for several reasons: they are able to generate electricity by using iron in electrodes as an electron acceptor, for example. They have potential uses in electronics *expand*; they may be used in bioremediation in mine drainage, or in remediation of radioactive uranium, reducing it to a less active form *expand*.,28804,1934027_1934003_1933965,00.html
