- aggregation title "Simultaneous production and extraction of acetate from CO2 during microbial electrosynthesis".
- aggregation abstract "Conversion of CO2 into organics using autotrophic electro-active cultures is developing rapidly. We can now produce bioproducts such as acetate at concentrations up to 10 g/L. Whereas production rates are limited by product accumulation, reversely the still-low concentrations preclude conventional product recovery. Here we present a novel three-compartment electrochemical cell reactor design for simultaneous bioproduction and product extraction. This cell combines a cathode compartment for microbial electrosynthesis (MES), a membrane electrolysis step for extraction of the produced acetate, and an acid-generating anode. The acetate is trapped in its acidic form in the low pH middle compartment and formation of chlorinated by-products at the anode is avoided using a second membrane. Abiotic system characterization in which acetate was gradually dosed into the cathode compartment led to the conclusion that electricity-driven production and extraction can be obtained effectively using this system, allowing the extraction of acetate above the 1 g/L level at the cathode. The coulombic efficiency of extraction increased from 5% at cathodic acetate concentrations below 1 g/L to 25% at 3 g/L of acetate, which is line with the expectations at low current densities (1.5 A/m²) and low titers. The extraction step lowered the cathodic acetate concentration by 40%, which may effectively decrease product inhibition. Preliminary results from biotic MES experiments confirm these findings: for a cathodic concentration of 233 mg acetate/L, 46 mg/L was obtained in the middle compartment, while 233 mg/L was obtained in the middle compartment for a cathodic concentration of 968 mg/L. The integrated approach is a step forward in the development of MES as a sustainable production technology.".
