Growth of Acidithiobacillus ferrooxidans ATCC 23270 in thiosulfate under oxygen-limiting conditions generates extracellular sulfur globules by means of a secreted tetrathionate hydrolase
(Frontiers Research Foundation, 2011)
Production of sulfur globules during sulfide or thiosulfate oxidation is a characteristic feature of some sulfur bacteria. Although their generation has been reported in Acidithiobacillus ferrooxidans, its mechanism of ...
Gene expression modulation by chalcopyrite and bornite in Acidithiobacillus ferrooxidans
(Springer, 2010-07-01)
Acidithiobacillus ferrooxidans is a mesophilic, acidophilic, chemolithoautotrophic bacterium that obtains energy from the oxidation of ferrous iron (Fe(2+)), elemental sulfur and reduced sulfur compounds. The industrial ...

Acidithiobacillus ferrooxidans is a mesophilic, acidophilic, chemolithoautotrophic bacterium that obtains energy from the oxidation of ferrous iron (Fe(2+)), elemental sulfur and reduced sulfur compounds. The industrial ...
Molecular characterization of Acidithiobacillus ferrooxidans and A-thiooxidans strains isolated from mine wastes in Brazil
(Springer, 2001-10-01)
Nineteen strains of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans, including 12 strains isolated from coal, copper, gold and uranium mines in Brazil, strains isolated from similar sources in other countries ...
Oxidative dissolution of bornite by Acidithiobacillus ferrooxidans
(Elsevier B.V., 2010-01-01)
The oxidation of finely ground (-200 mu m) bornite (Cu(5)FeS(4)) by Acidithiobacillus ferrooxidans was evaluated in oxygen uptake and shake flasks experiments. The oxidation was a net acid-consuming reaction. Residual ...

The oxidation of finely ground (-200 mu m) bornite (Cu(5)FeS(4)) by Acidithiobacillus ferrooxidans was evaluated in oxygen uptake and shake flasks experiments. The oxidation was a net acid-consuming reaction. Residual ...
UV-Irradiated Strain of Acidithiobacillus ferrooxidans Improved Copper Bioleaching in Chalcopyrite
(Asce-amer Soc Civil Engineers, 2018-08-01)
Bioleaching is a process that uses microorganisms to perform dissolution of sulfide minerals. Actually, most copper is found as chalcopyrite ore, which is the most abundant form of copper sulfide, but it is recalcitrant ...
Differential gene expression in Acidithiobacillus ferrooxidans LR planktonic and attached cells in the presence of chalcopyrite
(Wiley-Blackwell, 2014-07-01)
Acidithiobacillus ferrooxidans is commonly used in bioleaching operations to recover copper from sulfide ores. It is commonly accepted that A. ferrooxidans attaches to mineral surfaces by means of extracellular polymeric ...
Bioinformatic Prediction of Gene Functions Regulated by Quorum Sensing in the Bioleaching Bacterium Acidithiobacillus ferrooxidans
(2013)
The biomining bacterium Acidithiobacillus ferrooxidans oxidizes sulfide ores
and promotes metal solubilization. The efficiency of this process depends on the
attachment of cells to surfaces, a process regulated by quorum ...
