Article Abstract
Sustainable production of solar-based chemicals is possible by mimicking the natural photosynthetic mechanism. To realize the full potential of solar-to-chemical production, the artificial means of photosynthesis and the biological approach should complement each other. The recently developed hybrid microbe-metal interface combines an inorganic, semiconducting light-harvester material with efficient and simple microorganisms, resulting in a novel metal-microbe interface that helps the microbes to capture energy directly from sunlight. This solar energy is then used for sustainable biosynthesis of chemicals from CO. This review discusses various approaches to improve the electron uptake by microbes at the bioinorganic interface, especially self-photosensitized microbial systems and integrated water splitting biosynthetic systems, with emphasis on CO bioelectrosynthesis.

Article Synopsis
- Hybrid systems combining synthetic materials with biological elements can enhance sustainable and efficient catalysis, but they require interdisciplinary insights due to their complex nature.
- This Perspective focuses on nitrogen and carbon monoxide fixation, discussing critical aspects of the material-microbe interface and how physical and biological sciences impact biohybrid performance.
- Key topics include evaluating catalytic performance, exploring interactions at the materials-biology interface, and identifying challenges and opportunities for advancing our understanding of abiotic-biotic catalysis.
Synergistic material-microbe interface toward deeper anaerobic defluorination.

Per- and polyfluoroalkyl substances (PFAS), particularly the perfluorinated ones, are recalcitrant to biodegradation. By integrating an enrichment culture of reductive defluorination with biocompatible electrodes for the electrochemical process, a deeper defluorination of a C-perfluorinated unsaturated PFAS was achieved compared to the biological or electrochemical system alone. Two synergies in the bioelectrochemical system were identified: i) The in-series microbial-electrochemical defluorination and ii) the electrochemically enabled microbial defluorination of intermediates.

An efficient and cheap energization of microbial biocatalysts is essential in current biotechnological processes. A promising alternative to the use of common organic or inorganic electron donors is the semiconductor nanoparticles (SNs) that absorb light and transfer electrons (photoelectrons) behaving as artificial photosynthetic systems (biohybrid systems). Excited photoelectrons generated by illuminated SNs are highly reductive and readily accepted by membrane-bound proteins and electron shuttles to drive specific cell reduction processes and energy generation in microbes.
