| 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 CO 2 . Herein, we present the coupled electrocatalytic and microbial catalysis of the C5‐polymer precursors mesaconate and 2 S ‐methylsuccinate from CO 2 and electric energy by in situ coupling electrochemical and microbial catalysis at 1 L‐scale. In the first phase, 6.1 ± 2.5 mM formate was produced by electrochemical CO 2 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 2 S ‐methylsuccinate, respectively. The proof‐of‐concept shows an overall conversion efficiency of 0.2% being 0.4% of the theoretical maximum. |
