[Digestion] Reaction Kinetics for AD

[Anand Karve]

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.
Yours
