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.
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.
The gram-negative bacterium grows best at 30 °C at pH 2 and Fe 2+ concentrations of 10 M, but growth still occurs at pH values of less than 1.
Genetics
The ATCC 23270 type strain has one circular chromosome of 2.9 million base pairs and a G+C content of 59%. Genome sequencing has shown 2070 genes that code for a protein with a known function, while 1147 hypothetical proteins have been found. The bacterium contains a gene that makes it toluene-resistant. Genes for chemotaxis and locomotion (flagella) have not been observed.
