Abstract
The subsurface seabed is a gigantic bioreactor and would also be a substantial source for methane on earth, if rising gases were not efficiently utilized by microbial methanotrophic guilds. More than 90 percent of the methane rising from the subsurface ocean is oxidized anaerobically with sulfate as electron acceptor. It is a striking fact that this process of unknown functioning, carried out by very few phylogenetic groups of archaea, substantially effects atmospheric concentrations of methane.
