Acidithiobacillus thiooxidans and its potential application

Applied Microbiology and Biotechnology, 2019
Acidithiobacillus thiooxidans (A. thiooxidans) is a widespread, mesophilic, obligately aerobic, extremely acidophilic, rod-shaped, and chemolithoautotrophic gram-negative gammaproteobacterium. It can obtain energy and electrons from the oxidation of reducible sulfur, and it can fix carbon dioxide and assimilate nitrate, nitrite, and ammonium to satisfy

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.
