Methanosarcina barkeri can produce methane anaerobically through different metabolic pathways. M. barkeri can subsume a variety of molecules for ATP production, including methanol, acetate, methylamines, and different forms of hydrogen and carbon dioxide.〔 Although it is a slow developer and is sentient of change in environmental conditions, M. barkeri is able to grow in a variety of different substrates, adding to its appeal for genetic analysis. Additionally, M barkeri is the first organism in which the amino acid pyrrolysine was found. == Location and Structure == The fusaro strain of M. barkeri was found in mud samples taken from Lake Lago del Fusaro, a freshwater lake near Naples.〔 M. barkeri also lives in the rumen of cattle, where it works in tandem with other microbes to digest polymers.〔 Methanosarcina barkeri can also be found in sewage, landfills, and in other freshwater systems.〔 Methanosarcina barkeri are lobed cocci. They consistently form unorganized clusters, and can grow large enough to be seen by the naked eye.〔 The cells also grow large and spherical, producing a positive Gram strain.〔 M. barkeri has a thick cell wall compounded by a short lipid cell membrane that is similar in structure to most other methanogens.〔 M. barkeri str. fusaro has no flagellum but has potential for movement through the creation of gas vesicles.〔 These gas vesicles have only been produced in the presence of hydrogen and carbon dioxide, likely acting as a response to a hydrogen gradient.〔 M. barkeri’s chromosome is large and circular, derived from its remarkable ability to metabolize a variety of different carbon molecules.〔 This offers the species an advantage as though it is immotile, it can adapt to its environment depending on the energy sources available. M. barkeri’s circular plasmid consists of 26 genes.〔 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「Methanosarcina barkeri」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.
