Reduction of vanadium(V) with Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans
Bioresource Technology, 2004 Biotechnological leaching has been proposed as a suitable method for extraction of vanadium from spent catalysts and oil ash. In the biological leaching process, the vanadium(V) can be reduced to vanadium(IV), which is a less toxic and more soluble form of the vanadium.

Minerals Engineering, 2007 Abstract A research-grade mineral sample that contained marcasite and pyrite (FeS 2 ) was subjected to the oxidation by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans . Oxidation of FeS 2 by A. ferrooxidans produced acid, and the redox potential increased with sulfide dissolution and the oxidation of Fe 2+ .

Bioleaching of As from the soil in an abandoned Ag-Au mine was carried out using Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans. A. ferrooxidans is an iron oxidizer and A. thiooxidans is a sulfur oxidizer. These two microbes are acidophilic and chemoautotrophic microbes.

The grown conditions of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans were investigated, and then experiments were conducted to research the bioleaching behaviors of crude ore of copper sulfide and hand-picked concentrates of chalcopyrite by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans.

Process Biochemistry, 2002 Abstract Chalcopyrite oxidation was evaluated with two acidophilic thiobacilli that are important in bioleaching processes. Acidithiobacillus thiooxidans in pure culture did not oxidize CuFeS2 but oxidized externally added S0 in the presence of CuFeS2.

Acidithiobacillus ferrooxidans
Trends in Microbiology, 2019Acidithiobacillus ferrooxidans is by far the most widely studied of all extremely acidophilic prokaryotes. While it is found in many types of natural low-pH environments in a variety of geoclimatic contexts, it has been more widely cited in anthropogenic (mostly mine-impacted) environments.

Reduction of uranium(VI) by Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans
Hydrometallurgy, 2010Interaction of Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans with soluble uranium(VI) was studied. Acidithiobacillus thiooxidans aerobic cultures showed considerable decrement of uranium in solution when pH was set to 4 with KOH. This condition stabilized polythionates produced as a result of the oxidative sulphur metabolism and ...

Magnetic properties of Acidithiobacillus ferrooxidans
Materials Science and Engineering: C, 2013Understanding the magnetic properties of magnetotactic bacteria (MTBs) is of great interest in fields of life sciences, geosciences, biomineralization, biomagnetism, and planetary sciences. Acidithiobacillus ferrooxidans (At. ferrooxidans), obtaining energy through the oxidation of ferrous iron and various reduced inorganic sulfur compounds, can ...
