Reduction of vanadium(V) with Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans

Bioresource Technology, 2004
Biotechnological leaching has been proposed as a suitable method for extraction of vanadium from spent catalysts and oil ash. In the biological leaching process, the vanadium(V) can be reduced to vanadium(IV), which is a less toxic and more soluble form of the vanadium.

Draft genome sequence of the type strain of the sulfur-oxidizing acidophile, Acidithiobacillus albertensis (DSM 14366) [PDF]

Standards in Genomic Sciences, 2017
Acidithiobacillus albertensis is an extremely acidophilic, mesophilic, obligatory autotrophic sulfur-oxidizer, with potential importance in the bioleaching of sulfidic metal ores, first described in the 1980s. Here we present the draft genome sequence of

Oxidation of isochemical FeS2 (marcasite–pyrite) by Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans

Minerals Engineering, 2007
Abstract A research-grade mineral sample that contained marcasite and pyrite (FeS 2 ) was subjected to the oxidation by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans . Oxidation of FeS 2 by A. ferrooxidans produced acid, and the redox potential increased with sulfide dissolution and the oxidation of Fe 2+ .

Oxidation of chalcopyrite by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans in shake flasks

Process Biochemistry, 2002
Abstract Chalcopyrite oxidation was evaluated with two acidophilic thiobacilli that are important in bioleaching processes. Acidithiobacillus thiooxidans in pure culture did not oxidize CuFeS2 but oxidized externally added S0 in the presence of CuFeS2.

Metabolomic study of Chilean biomining bacteria Acidithiobacillus ferrooxidans strain Wenelen and Acidithiobacillus thiooxidans strain Licanantay [PDF]

Metabolomics, 2012
In this study, we present the first metabolic profiles for two bioleaching bacteria using capillary electrophoresis coupled with mass spectrometry. The bacteria, Acidithiobacillus ferrooxidans strain Wenelen (DSM 16786) and Acidithiobacillus thiooxidans strain Licanantay (DSM 17318), were sampled at different growth phases and on different substrates ...

Biofertilzers with natural phosphate, sulphur and Acidithiobacillus in a siol with low available-P

Scientia Agricola, 2003
The production of mineral fertilizers is a expensive process, since it requires high energy consumption, and cannot be produced by small farmers. Laboratory assays were conducted to produce P-biofertilizers from natural phosphate (B5, B10, B15, B20 ...

Biocompatibility Research of Magnetosomes Synthesized by <i>Acidithiobacillus ferrooxidans</i>. [PDF]

Int J Mol Sci
Magnetosomes are magnetic nanocrystals synthesized by bacteria that have important application value in biomedicine. Therefore, it is very important to evaluate their biocompatibility. It has been reported that the extremophilic acidophilic bacterium Acidithiobacillus ferrooxidans, which is aerobic, can synthesize intracellular Fe3O4 magnetosomes.

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

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.
