Ex-situ bioremediation of U(VI) from contaminated mine water using Acidithiobacillus ferrooxidans strains

Frontiers in Environmental Science, 2016
The ex-situ bioremoval of U(VI) from contaminated water using Acidithiobacillus ferrooxidans strain 8455 and 13538 was studied under a range of pH and uranium concentrations. The effect of pH on the growth of bacteria was evaluated across the range 1.5 –

Properties of realgar bioleaching using an extremely acidophilic bacterium and its antitumor mechanism as an anticancer agent

Biological Research, 2017
Realgar is a naturally occurring arsenic sulfide (or Xionghuang, in Chinese). It contains over 90% tetra-arsenic tetra-sulfide (As4S4). Currently, realgar has been confirmed the antitumor activities, both in vitro and in vivo, of realgar extracted using ...

Acidithiobacillus ferrooxidans Leaching of Silica-Sulfide Gold Ores from May-Hibey Deposits, Tigray, Ethiopia

International Journal of Chemical Engineering
Oxidative leaching is an inexpensive alternative to using chemical cyanide extraction methods for gold from low-grade gold sulfide. Oxidation of finely ground gold-bearing ore by Acidithiobacillus ferrooxidans was evaluated in terms of cell density, pH ...

Isoxazole-based corrosion inhibitor for mild steel in acidic medium: adsorption, electrochemical, and computational studies

Discover Chemistry
A novel heterocyclic isoxazole compound was assessed as an efficient corrosion inhibitor for mild steel in 1 M HCl. The corrosion inhibition performance was systematically evaluated using gravimetric and electrochemical impedance spectroscopy techniques.

Comparative genomics analysis of the reason for 12C6+ heavy-ion irradiation in improving Fe3O4 nanoparticle yield of Acidithiobacillus ferrooxidans

Ecotoxicology and Environmental Safety
The Fe3O4 nanoparticle synthesized by Acidithiobacillus ferrooxidans have a broad practical value, while the low yield limits their commercial application. Herein, we employed a 12C6+ heavy-ion beam to induce mutagenesis of A.

A Lux-like Quorum Sensing System in the Extreme Acidophile Acidithiobacillus ferrooxidans

Biological Research, 2005
The genome of the acidophilic, proteobacterium Acidithiobacillus ferrooxidans, contains linked but divergently oriented genes, termed afeI and afeR, whose predicted protein products are significantly similar to the LuxI and LuxR families of proteins.
