Coupled Electrochemical and Microbial Catalysis for the Production of Polymer Bricks.

ABSTRACT: Power-to-X technologies have the potential to pave the way towards a future resource-secure bioeconomy as they enable the exploitation of renewable resources and CO₂ . Herein, the coupled electrocatalytic and microbial catalysis of the C₅ -polymer precursors mesaconate and 2S-methylsuccinate from CO₂ and electric energy by in situ coupling electrochemical and microbial catalysis at 1 L-scale was developed. In the first phase, 6.1±2.5 mm formate was produced by electrochemical CO₂ reduction. In the second phase, formate served as the substrate for microbial catalysis by an engineered strain of Methylobacterium extorquens AM-1 producing 7±2 μm and 10±5 μm of mesaconate and 2S-methylsuccinate, respectively. The proof of concept showed an overall con
