Thiobacillus ferrooxidans has been known to reduce acetylene to ethylene in the absence of nitrogen sources indicating the possession of nitrogenase enzyme by this microbe ( Mackintosh, 1978 ). [11] Bioleaching The common sulfur-oxidizing bacterium Thiobacillus thiooxidans is a chemo-lithotroph utilizing thiosulfate and sulfide as sources of energy to produce sulfuric acid. Diverse sulfur-metabolic pathways and corresponding regulatory systems Acidithiobacillus thiooxidans was once referred to as Thiobacillus thiooxidans before it was reclassified to a newly classified genus, Acidithiobacillus within the Gammaproteobacteria in 2000 (Kelly and Wood, 2000). Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. 930 tax ID * [Ref.2 Other applications of bioleaching include the ability The bacteria belonging to the families of the Thiobacteriaceae, Beggiatoaceae and Achromatiaceae are commonly called the colourless sulfur bacteria. Sphalerite (ZnS) oxidation was monitored in Thiobacillus ferrooxidans and Thiobacillus thiooxidans cultures and in abiotic controls by X-ray diffraction (XRD) analysis of solid Background Habitats colonized by acidophiles as an ideal physical barrier may induce genetic exchange of microbial members within the common communities, but little is known about how species in extremely acidic environments diverge and evolve.
