Methanogenic bacteria in seawater
WebMethanogenesis Some methanogenic bacteria use acetic acid (CH3COOH) and hydrogen to make methane. Write a balanced chemical reaction for the synthesis of methane and … WebHigh methane emissions from coastal regions are caused by high fluxes of methane from the sediment, of which more than two-thirds is biogenic in origin [i.e., produced by a microbial process called methanogenesis ( 4, 5 )]. Methanogenesis is a form of anaerobic respiration during which oxidized carbon is used as the terminal electron acceptor.
