Methylotrophs are a diverse group of microorganisms that can use reduced one-carbon compounds, such as methanol or methane, as the carbon source for their growth; and multi-carbon compounds that contain no carbon bonds, such as dimethyl ether and dimethylamine. This group of microorganisms also includes those capable of assimilating reduced one-carbon compounds by way of carbon dioxide using the ribulose bisphosphate pathway.〔Anthony, C. "The Biochemistry of Methylotrophs". Academic press, 1982, p. 2-3〕 These organisms should not be confused with methanogens which on the contrary produce methane as a by-product from various one-carbon compounds such as carbon dioxide. Some methylotrophs can degrade the greenhouse gas methane, and in this case they are called methanotrophs. The methanotroph ''Methylococcus capsulatus'' is used to degrade methane and other pollutants. The abundance, purity, and low price of methanol compared to commonly used sugars make methylotrophs competent organisms for production of amino acids, vitamins, recombinant proteins, single-cell proteins, co-enzymes and cytochromes. ==General Microbiology== Methylotrophs are a diverse group, including both Gram-negative and Gram-positive genera. None of them make resting structures like exospores or cysts and none of them have the complex intracellular membrane systems that characterize methanotrophs growing on methane There are two sub groups: 1- obligate methylotrophs. 2- facultative methylotrophs. 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「methylotroph」の詳細全文を読む スポンサード リンク
