Sulfur Oxidation in the Acidophilic Autotrophic Acidithiobacillus spp.

Frontiers in Microbiology, 2019
Sulfur oxidation is an essential component of the earth’s sulfur cycle. Acidithiobacillus spp. can oxidize various reduced inorganic sulfur compounds (RISCs) with high efficiency to obtain electrons for their autotrophic growth.

Bioleaching Coal Gangue with a Mixed Culture of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans [PDF]

Minerals, 2021
A mixed culture of A. ferrooxidans and A. thiooxidans isolated from a coal gangue dump was used to bioleach coal gangue in a column reactor to investigate the leaching of elements. The changes of metal ions (Fe, Mn and Cr) and sulfate in the leaching solution, elemental composition, mineral components and sulfur speciation of the coal gangue before and

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 ...

Construction of recombinant mercury resistant Acidithiobacillus caldus [PDF]

Microbiological Research, 2011
A mercury-resistant plasmid of pTMJ212 which was able to shuttle between Acidithiobacillus caldus and Escherichia coli was constructed by inserting the mercury resistant determinants, the mer operon of Acidithiobacillus ferrooxidans, into the IncQ plasmid of pJRD215.
