Dear Mr. Muthui, aerobic reactions combine atmospheric oxygen with the substrate. This type of oxydation is exothermic. You can compare it with combustion of biomass. Being living organisms, the methanogens do need oxygen for their metabolism, but they take it up from the feedstock and not from the atmosphere. This is how they convert acetic acid, a carbohydrate, into methane, which is a hydrocarbon. This reaction does not give out any energy in the form of heat.
