Molecular genetics of Thiobacillus ferrooxidans
Microbiological Reviews, 1994 Thiobacillus ferrooxidans is a gram-negative, highly acidophilic (pH 1.5 to 2.0), autotrophic bacterium that obtains its energy through the oxidation of ferrous iron or reduced inorganic sulfur compounds. It is usually dominant in the mixed bacterial populations that are used industrially for the extraction of metals such as copper and uranium from ...

Studies on the Metabolism of Thiobacillus thiocyanoxidans [PDF]
Journal of General Microbiology, 1954 SUMMARY: The investigation of the metabolism of thiocyanate by pure cultures of Thiobacillus thiocyanoxidans was complicated by the fact that thiocyanate serves both as source of energy and as source of carbon and nitrogen. It was, therefore, difficult to separate oxidation from carbon dioxide fixation. The equation which best represented the resultant
