Potential biological pathway for atmospheric methane production
Methane
Aerobic methane production is a potential biological pathway for atmospheric methane (CH4) production under oxygenated conditions. The existence of this pathway was first theorized in 2006.[1] While significant evidence suggests the existence of this pathway,[1][2][3][4][5] it remains poorly understood and its existence is controversial.[2][6][7] Naturally occurring methane is mainly produced by the process of methanogenesis, a form of anaerobic respiration used by microorganisms as an energy source.[8] Methanogenesis usually only occurs under anoxic conditions. By contrast, aerobic methane production is thought to occur in oxygenated environments under near-ambient conditions. The process involves non-microbial methane generation from terrestrial plant-matter. Temperature and ultraviolet light are thought to be key factors in this process.[1] Methane may also be produced under aerobic conditions in near-surface ocean water, a process which likely involves the degradation of methylphosphonate.[9]
