''Acidithiobacillus'' is a genus of Proteobacteria. Like all Proteobacteria, ''Acidithiobacillus'' is Gram-negative. The members of this genus used to belong to ''Thiobacillus'', before they were reclassified in the year 2000. * ''Acidithiobacillus ferrooxidans'' (syn. ''Thiobacillus ferrooxidans'') lives in pyrite deposits, metabolizing iron and sulfur and producing sulfuric acid. * ''Acidithiobacillus thiooxidans'' (syn. ''Thiobacillus thiooxidans'', ''Thiobacillus concretivorus''〔) consumes sulfur and produces sulfuric acid. Though first isolated from the soil〔 ()〕 it has also been observed causing biogenic sulfide corrosion of concrete sewer pipes by altering hydrogen sulfide sewage gas into sulfuric acid.〔 ()〕 Both of these bacteria are used in a mining technique called bioleaching whereby metals are extracted from their ores through oxidation. The bacteria are used as catalysts. It is also used in the biomining process. ==Genus ''Acidithiobacillus''== ''Acidithiobacillus'' is the most important genus of chemolithotrophs that metabolize sulfur. It includes motile rod-shaped cells that can be isolated from rivers, canals, acidified sulfate soils, mine drainage effluents, and other mining areas. These Thiobacilli are adapted to wide variations of temperature and pH and can be readily isolated and enriched. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acidithiobacillus」の詳細全文を読む スポンサード リンク
