Respuestas, 2019 One of the main characteristics of the microorganisms used in the leaching process is their capacity to adapt to aggressive environments, characterized by a notable presence of heavy metals. In this study the adaptation of the strains Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Leptospirillum ferrooxidans was evaluated on a ...

Oxidative dissolution of bornite by Acidithiobacillus ferrooxidans
Process Biochemistry, 2010 Abstract The oxidation of finely ground (−200 μm) 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 bornite was not detected by X-fray diffraction in solids after 2 days of contact in acid leach solution, indicating that the ...

Valorization of Phosphorus Secondary Raw Materials by Acidithiobacillus ferrooxidans [PDF]
Molecules, 2017 This paper presents the possibility of producing phosphorus fertilizers through Acidithiobacillus ferrooxidans utilization in secondary raw materials solubilization. Phosphorus was obtained from the bones of poultry and fish as well as from Morocco phosphorite. Four doses of poultry bones and fish bones were used in the experiment (2, 4, 10 and 20 g/L)

Periplasmic Proteins of the Extremophile Acidithiobacillus ferrooxidans [PDF]
Molecular & Cellular Proteomics, 2007 Acidithiobacillus ferrooxidans is a chemolithoautotrophic acidophile capable of obtaining energy by oxidizing ferrous iron or sulfur compounds such as metal sulfides. Some of the proteins involved in these oxidations have been described as forming part of the periplasm of this extremophile.

Phylogenetic heterogeneity of the species Acidithiobacillus ferrooxidans [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2003 Polyphasic genotypic analysis of 25 Acidithiobacillus ferrooxidans strains isolated from ores and ore concentrates collected in different regions of the world showed considerable strain heterogeneity. Restriction patterns of the chromosomal DNA of these strains obtained by PFGE were specific for each strain.
