Where does methane come from naturally?
Methane
anaerobic respiration used by organisms that occupy landfill, ruminants (for example cows or cattle), and the guts of termites
The final step in the process is catalyzed by the enzyme Coenzyme-B sulfoethylthiotransferase. Methanogenesis is a form of anaerobic respiration used by organisms that occupy landfill, ruminants (for example cows or cattle), and the guts of termites.
