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 ...

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 ...

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.

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.

Effect of polyvinyl pyrrolidone on chalcopyrite bioleaching with Acidithiobacillus ferrooxidans
Hydrometallurgy, 2021Chalcopyrite (CuFeS2) is the most abundant copper-bearing mineral in nature. Large amounts of low-grade chalcopyrite ores cannot easily be utilized due to technical and economic limitations, which lead to an enormous waste of resources.

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+ .

As the predominant treatment approach of acid mine drainage (AMD), lime neutralization often exhibits inefficiencies since the abundance of iron and sulfate in AMD usually form iron hydroxide and gypsum precipitate coatings on the surface of lime.
