...In that case, they are called chemoorganic oxidolithotrophs, and the above mentioned ones are called chemoorganic oxidolithotrophs. A group of bacteria called methylotrophs oxidize methane or methanol to use the energy, but fix the compound formaldehyde produced in the oxidation process instead of CO2 (ribulose-5-phosphate + formaldehyde → D-arabino-3-hexulose-6-phosphate → fructose-6-phosphate). The existence of such a variety of energy acquisition systems and their associated carbon fixation systems is thought to be the result of the differentiation of these systems in response to changes in the Earth's environment (such as the presence or absence of oxygen and oxidizing substrates) during the course of biological evolution, and provides interesting material for the study of metabolic evolution. ... *Some of the terminology that mentions "methylotroph" is listed below.

…その場合にはこれらを化学合成有機酸化無機栄養生物と呼び,先に述べたものを化学合成無機酸化無機栄養生物と呼ぶ。メチロトローフmethylotrophと呼ばれる一群の細菌は,メタンまたはメタノールを酸化してそのエネルギーを利用するが,酸化過程で生じる化合物ホルムアルデヒドをCO2の代りに固定する(リブロース‐5‐リン酸+ホルムアルデヒド―→D‐アラビノ‐3‐ヘクスロース‐6‐リン酸―→フルクトース‐6‐リン酸)。エネルギー獲得系とこれに共役した炭酸固定系がこのように多様な形で存在するということは,生物進化の過程で地球上の環境(酸素や酸化基質の有無など)の変化に応じてこれらの系が分化を遂げた結果であると考えられ,代謝系進化の研究に興味深い素材を提供している。… ※「methylotroph」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
