Ozuolmez and colleagues observed a similar shift from high numbers of sulfate-reducers to higher numbers of methanogens during a cocultivation of Methanosaeta concilii and Desulfovibrio vulgaris on acetate [80].
Methane can be generated in two ways by two types of methanogens: (a) acetoclastic methanogens that produce methane from acetic acid and (b) hydrogenotrophic methanogens that utilize hydrogen to reduce carbon dioxide.
Simple substrates such as methanol, mono-, bi- and trimethylamine are important to methanogens, while SRB are capable of degrading more complex substances (Lyimo et al., 2002; Wilms et al., 2007; Muyzer & Stams, 2008).

The archea are 80 percent efficient at conserving the electrical energy into the chemical bonds of methane, good enough that Logan and his team want to use the methanogen to store energy generated by intermittent power sources, like wind, solar or tidal energy.
