Methanogen - Simple English Wikipedia, the free encyclopedia

Methanogens are known to produce methane from substrates such as H2/CO2, acetate, formate, methanol and methylamines in a process called methanogenesis. Different methanogenic reactions are catalyzed by unique sets of enzymes and coenzymes. While reaction mechanism and energetics vary between one reaction and another, all of these reactions contribute to net positive energy production by creating ion concentration gradients that are used to drive ATP synthesis. … Web24 dec. 2024 · Methanogens have been found buried under kilometers of ice in Greenland, as well as in the “solid” rock of the Earth’s crust, kilometers below the surface.
