Thiobacillus ferrooxidans

Acidithiobacillus ferrooxidans is a bacterium that sustains its life cycle at extremely low pH values, and it is one of the very few organisms that gain energy from oxidating ferrous iron (Fe +II). It can make copper from ores water-soluble, and it can sequester both carbon and nitrogen from the atmosphere.[1]

Not only is A. ferrooxidans the best-studied of the acidophilic bacteria. During mining activities, the bacterium plays a crucial role in producing harmful acidic and metal-rich drainage water through the dissolution of sulfide minerals, but it also recovers precious dissolved metals.[2]

The gram-negative bacterium grows best at 30 °C at pH 2 and Fe 2+ concentrations of 10-1 M, but growth still occurs at pH values of less than 1.[1]
