Cover Story: Developing a thermodynamic model for analyzing the relationship between externally applied energy and electrogenic microbial biomass is an essential step for the precise simulation result prediction of bioelectrochemical systems (BESs). In this study, we developed a bioenergetic model based on the thermodynamics of microbial yield to calculate the optimum voltage for organic matter oxidation at the bioanode, enabling efficient carbon dioxide (CO2) reduction to methane (CH4) through electromethanogenesis at the biocathode. The model identified applied voltage −0.3 V vs. SHE on the biocathode as optimal CH4 production and microbial growth, regardless of ohmic losses. Validation with experimental data from a lab-scale BES reactor has confirmed that simulation tools effectively support the up-scaling of experimental setups. View this paper
