Cathode biofilm, electromethanogenic reactor, day 256
bioreactor metagenome
Cathode biofilm (nickel foam) from the electromethanogenic reactor (EMR) of a two-stage bioelectrochemical reactor treating tequila vinasse; collected at day 256 of operation under applied voltage 0.8 V. The EMR was fed EFR effluent neutralized to pH 7.0 with 5 M NaOH.
