Unveiling the Bioleaching Versatility of Acidithiobacillus ferrooxidans

Microorganisms
Acidithiobacillus ferrooxidans is a Gram-negative bacterium that thrives in extreme acidic conditions. It has emerged as a key player in biomining and bioleaching technologies thanks to its unique ability to mobilize a wide spectrum of elements, such as Li, P, V, Cr, Fe, Ni, Cu, Zn, Ga, As, Mo, W, Pb, U, and its role in ferrous iron oxidation and ...

Mechanism of Growth Inhibition by Tungsten in Acidithiobacillus ferrooxidans

Bioscience, Biotechnology, and Biochemistry, 2001
Cell growth of three hundred iron-oxidizing bacteria isolated from natural environments was inhibited strongly by 0.05 mM, and completely by 0.2 mM of sodium tungstate (Na2WO4), respectively. Since no great difference in the level of tungsten inhibition was observed among the 300 strains tested, the mechanism of inhibition by Na2WO4 was studied with ...

Acetogenic Methane‐Carbon Monoxide Comproportionation: An Exergonic but Unobserved Microbial Metabolism

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Microbial metabolism relies on redox reactions that exploit chemical disequilibria. While aerobic carbon oxidation, carbon fixation, and fermentation are well studied, the broader space of anaerobic carbon redox reactions remains underexplored.

Single and cooperative bioleaching of sphalerite by two kinds of bacteria—Acidithiobacillus ferriooxidans and Acidithiobacillus thiooxidans

Transactions of Nonferrous Metals Society of China, 2008
Abstract A cooperative bioleaching ( Acidithiobacillus ferriooxidans and Acidithiobacillus thiooxidans ) and single bioleaching ( Acidithiobacillus ferriooxidans or Acidithiobacillus thiooxidans ) of sphalerite were investigated by X-ray diffractometry, energy dispersive spectrography and scanning electron microscopy.

EFFECT OF Acidithiobacillus thiooxidans-CYSTEINE INTERACTIONS ON PYRITE BIOOXIDATION BY Acidithiobacillus ferrooxidans IN THE PRESENCE OF COAL COMPOUNDS [PDF]

Brazilian Journal of Chemical Engineering, 2019
Abstract This study evaluated the biooxidation of pyrite contained in a Colombian coal (2.38 mm < particle size < 0.50 mm). The variables were cysteine concentration (0-600 mg/L) and culture type (pure Acidithiobacillus ferrooxidans (ATCC 23270) and a consortium of Acidithiobacillus thiooxidans (ATCC 15494) and Acidithiobacillus ferrooxidans).

Nano/Micro‐Engineered Hydrogel Carriers for Sustainable Agriculture: Bridging Structural Form to Field Performance

Advanced Sustainable Systems, Volume 10, Issue 3, March 2026.
ABSTRACT Hydrogels are 3D polymeric networks that can absorb and retain significant amounts of water and exhibit physical properties such as swelling and contraction in response to changes in the external environment. Owing to these unique physicochemical properties, hydrogels have attracted interest as effective solutions to key challenges in modern ...
