Oxidation of iron at a low pH does not create high yields of energy. However, to compensate for the oxidation of iron, a reduction must also occur to balance the reaction. At a low pH, protons can be subsequently reduced. Bacteria with this metabolic capacity are prevalent in acid-polluted and coal-mining environments.
