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

open access: yesBioresource 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.

Genetic engineering of the acidophilic chemolithoautotroph Acidithiobacillus ferrooxidans

Trends in Biotechnology, 2022
There are several natural and anthropomorphic environments where iron- and/or sulfur-oxidizing bacteria thrive in extremely acidic conditions. These acidophilic chemolithautotrophs play important roles in biogeochemical iron and sulfur cycles, are critical catalysts for industrial metal bioleaching operations, and have underexplored potential in future

Acidithiobacillus ferrooxidans and its potential application

Extremophiles, 2018
The widely distributed Acidithiobacillus ferrooxidans (A. ferrooxidans) lives in extremely acidic conditions by fixing CO2 and nitrogen, and by obtaining energy from Fe2+ oxidation with either downhill or uphill electron transfer pathway and from reduced sulfur oxidation. A.

The role of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans in arsenic bioleaching from soil

Environmental Geochemistry and Health, 2013
Bioleaching of As from the soil in an abandoned Ag-Au mine was carried out using Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans. A. ferrooxidans is an iron oxidizer and A. thiooxidans is a sulfur oxidizer. These two microbes are acidophilic and chemoautotrophic microbes.

Application of Acidithiobacillus Ferrooxidans in Coal Flotation

open access: yesInternational Journal of Coal Preparation and Utilization, 2009
Bioflotation is a potential method for removing pyritic sulphur from coal. Sodium cyanide is a well-known depressant for pyrite in flotation of sulphide minerals; however, for coal this reagent is unacceptable from the environmental point of view. This study investigates an alternate to sodium cyanide; Acidithiobacillus Ferrooxidans, a nonharmful ...

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

open access: yesProcess 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.

Rapid and specific detection of Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans by PCR [PDF]

open access: yesHydrometallurgy, 2008
Abstract Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans are two of the most important bacteria in heap bioleaching processes of copper sulphide at common operating temperatures (18–24 °C). In this paper, both microorganisms were detected in solutions and ores coming from processes in 2 days, using specific amplification of 16S ...

Acidithiobacillus ferrooxidans

Trends in Microbiology, 2019
Acidithiobacillus ferrooxidans is by far the most widely studied of all extremely acidophilic prokaryotes. While it is found in many types of natural low-pH environments in a variety of geoclimatic contexts, it has been more widely cited in anthropogenic (mostly mine-impacted) environments.

Magnetic properties of Acidithiobacillus ferrooxidans

Materials Science and Engineering: C, 2013
Understanding the magnetic properties of magnetotactic bacteria (MTBs) is of great interest in fields of life sciences, geosciences, biomineralization, biomagnetism, and planetary sciences. Acidithiobacillus ferrooxidans (At. ferrooxidans), obtaining energy through the oxidation of ferrous iron and various reduced inorganic sulfur compounds, can ...

Adhesion forces between cells of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans or Leptospirillum ferrooxidans and chalcopyrite

Colloids and Surfaces B: Biointerfaces, 2012
The efficiency of copper leaching is improved by bacteria attached to chalcopyrite. Therefore, the study of the attachment mechanism to control leaching is important. The adhesion of three species of leaching microorganisms including Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Leptospirillum ferrooxidans to chalcopyrite was ...
