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.

Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

Advanced Science, Volume 12, Issue 29, August 7, 2025.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Bioleaching of low-grade uranium ore using Acidithiobacillus ferrooxidans [PDF]

Indian Journal of Microbiology, 2010
Bioleaching of uranium was carried out with Turamdih ore sample procured from Uranium Corporation of India Limited, Jaduguda. The bacterial strain that was used in the leaching experiments was isolated from the Jaduguda mine water sample. Efficiency of bioleaching was studied by varying parameters like pulp density and initial ferrous concentration as ...

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

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 ...
