Acidithrix ferrooxidans (A. ferrooxidans) is a heterotrophic, acidophilic and Gram-positive bacterium from the genus Acidithrix. The type strain of this species, A. ferrooxidans Py-F3, was isolated from an acidic stream draining from a copper mine in Wales.[1][3][4] This species grows in a variety of acidic environments such as streams, mines or geothermal sites.[1] Mine lakes with a redoxcline support growth with ferrous iron as the electron donor.[1][5] "A. ferrooxidans" grows rapidly in macroscopic streamer, producing greater cell densities than other streamer-forming microbes.[6] Use in a bioreactors to remediate mine waste has been proposed due to cell densities and rapid oxidation of ferrous iron oxidation in acidic mine drainage.[6] Exopolysaccharide production during metal substrate metabolism, such as iron oxidation helps to prevent cell encrustation by minerals.[5]
