Methanogenic prokaryotes
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. … Web1 nov. 2024 · Methanogens inhabit sulfidic environments where transition metals (e.g., Fe, Ni, Co, and Mo) predominantly exist as aqueous metal sulfide and/or minerals, and these are likely the preferred form of these elements over dissolved, ionic counterparts.
