title: Methanogenic communities on the electrodes of bioelectrochemical reactors without membranes.
abstract: Methane fermentation was successfully carried out in bioelectrochemical reactors without membranes under a working potential of -0.6 or -0.8 V (vs. Ag/AgCl) and neutral pH conditions. The hydrogenotrophic methanogens that dominated on the anodic and cathodic electrodes differed from those found on the electrodes in the control reactors without electrochemical reactions.
