Wood (2000). "Reclassification of some species of ''Thiobacillus'' to the newly designated genera ''Acidithiobacillus'' gen. nov., ''Halothiobacillus'' gen. nov. and ''Thermithiobacillus'' gen. nov." ''International Journal of Systematic and Evolutionary Microbiology'' 50: 511-516.〕 is a Gram-negative, rod-shaped bacterium that utilizes sulfur as its primary energy source.〔 It is mesophilic, with a temperature optimum of 28 °C.〔 This bacterium is commonly found in soil, sewer pipes and cave biofilms called snottites.〔 ''A. thiooxidans'' is used in the mining technique known as bioleaching, where metals are extracted from their ores through the action of microbes.〔〔 == Morphology == ''Acidithiobacillus thiooxidans'' is a Gram-negative, rod-shaped bacterium with rounded ends that occurs in nature either as single entities, as is the most common case, or sometimes in pairs, but rarely in triplets.〔Waksman, Selman A. and J. S. Joffe (1922). "Microorganisms concerned in the oxidation of sulfur in the soil: II. ''Thiobacillus thiooxidans'', a new sulfur-oxidizing organism isolated from the soil." ''Journal of bacteriology'' 7 (2): 239-256.〕 ''A. thiooxidans'' motility is due to a polar flagellum.〔 It is an obligate acidophile with an optimal pH of less than 4.0, but it also qualifies as an obligate aerobe and chemolithotroph.〔 Described as a colorless, sulfur-oxidizing bacterium, ''A. thiooxidans'' does not accumulate sulfur either within or outside of its very small cells, which have an average size of about 0.5 µm in diameter and 1 µm or less in length.〔 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 thiooxidans」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
