Simultaneous intensification of direct acetate cleavage and CO2 reduction to generate methane by bioaugmentation and increased electron transfer

Direct interspecies electron transfer coupled to CO2 reduction, DIET-CO2 reduction, to generate methane is proposed and prosperous in 2010s. It is well known that bioaugmentation and increased electron transfer benefit DIET-CO2 reduction. Herein, we studied whether other methanogenic pathways, such as H2-mediated methanogenic progress and direct acetate cleavage (acetoclastic methanogenesis), are simultaneously favorable in the presence of...
