Flow-Electrode Microbial Electrosynthesis for Increasing Production Rates and Lowering Energy Consumption Article

Na Chu, Donglin Wang, Houfeng Wang, Qinjun Liang, Jiali Chang, Yu Gao, Yong Jiang, Raymond Jianxiong Zeng

Engineering 2023, Volume 25, Issue 6, Pages 157-167 doi: 10.1016/j.eng.2021.09.015

Abstract:

The development of microbial electrosynthesis (MES) for renewable electricity-driven bioutilization of CO₂ has recently attracted considerable interest due to its ability to synthesize chemicals with the transition towards a circular carbon economy. However, the increase of acetate production and the decrease of energy consumption of MES using an advanced reactor design have received less attention. In this study, the total acetate production rate using novel flow-electrode MES reactors ((16 ± 1) g·m⁻²·d⁻¹) was double that using reactors without powder activated carbon (PAC) amendment ((8 ± 3) g·m⁻²·d⁻¹). The flow-electrode MES reactors had a Coulombic efficiency of 43.5% ± 3.1%, an energy consumption of (0.020 ± 0.005) kW·h·g⁻¹, and an energy efficiency of 18.7% ± 1.3% during acetate production. The flow-electrode with PAC amendment could decrease the net water flux and charge transfer resistance, while had little impact on the cell voltage, rheological behavior, and acetate adsorption. In the flow-electrode MES reactors, the expression of genes involving in energy production and conversion were increased, and the increase of acetate production was found correlated with the increased abundance of Acetobacterium. The Wood–Ljungdahl pathway (WLP) and reductive citric acid cycle (rTCA) were found to be the complete pathways responsible for carbon fixation. The concentrations of acetate in the stacked flow-electrode MES reached 7.0 g·L⁻¹. This study presents a new approach for the construction of scalable MES reactors with high-performance chemical generation and CO₂ utilization.
