Elemental S is oxidised primarily by bacteria of the genus Acidithiobacillus
, and the activity of these microorganisms dictates the release of S[O.sub.4.sup.2-] and [H.sup.+] ions.
The acidophilic iron(II) ion-oxidizing bacterium Acidithiobacillus
ferrooxidans was the first recognized microbe employed in the processes of extraction of metals from sulfidic ores by bioleaching.
Leaching of various metals, applying bacteria Acidithiobacillus
spp is being done for the recovery of copper, zinc and uranium by heap, dump and in situ leach techniques on a commercial scale.
ferrooxidans is an acidophile, living in environments with an optimal pH range of 1.5 to 2.5 (Shaikh et al., 2010) and is also thermophilic, preferring temperatures of 40 to 45[degrees]C (Karavaiko et al., 1998).
