A novel strain of an iron- and sulfur-oxidizing bacterium was isolated from a natural biotope at Kashen copper ore (Martakert Province, Republic of Artsakh). The strain is able to grow and oxidize ferrous ions in the range of pH 1.4–2.6 with optimal pH 2.

Microbial leaching of marmatite by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans
The bioleaching of marmatite in shaken flasks was studied. After leaching for 29 days, the leaching ratio of zinc was 91%. Three kinds of bacteria, mixture-based bacteria, 9K-based bacteria and sulfur-based bacteria were used in marmatite leaching, of which the mixture-based bacteria have the best leaching result while the sulfur-based bacteria have ...

Corrosion Behavior of Cast Iron in the Presence of Acidithiobacillus Ferrooxidans
Ferrooxidans bacteria occur widely in acid mine drainage water. This work examined the corrosion behavior of cast iron in the presence of the acidophilic iron-oxidizing bacterium Acidithiobacillus ferrooxidans (T.f).

Genetic variability in Acidithiobacillus spp. – a working horse of environmental biotechnologies
The genus Acidithiobacillus comprises 7 species of Gram-negative obligatory acidophilic chemolithotrophic bacteria that derive energy mainly from the oxidation of reduced sulphur compounds. Four of the species also catalyse the dissimilatory oxidation of
