It is the process of conversion of carbon compounds and other molecules into organic compounds. In this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source. This is done usually by microorganisms from the dark and deep hydrothermal vents of the sea floor.
