Microbial Community Analysis of a Methane-Producing Biocathode in a Bioelectrochemical System
Figure 2
(a) Current density (daily averages) and (b) methane production rate and cathodic electron efficiency with time. Cathode potential was changed from −0.7 V versus NHE to −0.6 V versus NHE (day 24), as indicated by the grey vertical line.
