Molecular genetics of Thiobacillus ferrooxidans

open access: yesMicrobiological 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 ...

Microbial- and Thiosulfate-Mediated Dissolution of Mercury Sulfide Minerals and Transformation to Gaseous Mercury

open access: yesFrontiers in Microbiology, 2015
Mercury (Hg) is a toxic heavy metal that poses significant human and environmental health risks. Soils and sediments, where Hg can exist as the Hg sulfide mineral metacinnabar (β-HgS), represent major Hg reservoirs in aquatic environments.

Studies on the Metabolism of Thiobacillus thiocyanoxidans [PDF]

open access: yesJournal 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
