Aerobic methane production

Top

Aerobic methane production is a recent discovery. While biomethanation usually only occurs under anoxic conditions, the generation of methane in an oxygenated environment under near-ambient conditions was discovered in 2006.[1] Although the emissions are smaller than the initial extrapolations, results clearly show the existence of a non-microbial CH4 production. Temperature and ultraviolet light are key factors involved in the aerobic generation of CH4 from organic matter. [2]


Aerobic methane production was discovered when David Karl, an Oceanographerin the School of Ocean and Earth Science and Technology at the University of Hawaii at Mânoa wondered about the exce of methane in the atmosphere. The discovery led to the idea that methylphosphonates that were discovred in the 1960's, that creates a certain type of bacteria which can lead to methane production.[3]
