Unexpected metabolic rewiring of CO₂ fixation in H₂-mediated materials-biology hybrids.

ABSTRACT: A hybrid approach combining water-splitting electrochemistry and H₂-oxidizing, CO₂-fixing microorganisms offers a viable solution for producing value-added chemicals from sunlight, water, and air. The classic wisdom without thorough examination to date assumes that the electrochemistry in such a H₂-mediated process is innocent of altering microbial behavior. Here, we report unexpected metabolic rewiring induced by water-splitting electrochemistry in H₂-oxidizing acetogenic bacterium Sporomusa ovata that challenges such a classic view. We found that the planktonic S. ovata is more efficient in utilizing reducing equivalent for ATP generation in the materials-biology hybrids than cells grown with H₂ supply, supported by our
