“…Thus, combining semiconductors and biocatalysts (e.g., living microorganisms) will leverage the advantages of both systems to enable light-driven chemical production from abundant resources such as N 2 , CO 2 , and H 2 O in a highly selective manner . Because photoautotrophic and photoheterotrophic bacteria can directly absorb light to produce chemicals, chemoautotrophic and chemoheterotrophic bacteria are often employed to build whole-cell-based semiartificial photosynthetic systems, which contribute to the sustainable production of chemicals . The prime task is to create biocompatible bioinorganic interfaces, which favor the transfer of energy from light to chemicals while maintaining the viability of microbes.…”

Recent advances in synthetic biology and materials science have given rise to a new form of materials, namely engineered living materials (ELMs), which are composed of living matter or cell communities embedded in self-regenerating matrices of their own or artificial scaffolds. Like natural materials such as bone, wood, and skin, ELMs, which possess the functional capabilities of living organisms, can grow, self-organize, and self-repair when needed. They also spontaneously perform programmed biological functions upon sensing external cues. Currently, ELMs show promise for green energy production, bioremediation, disease treatment, and fabricating advanced smart materials. This review first introduces the dynamic features of natural living systems and their potential for developing novel materials. We then summarize the recent research progress on living materials and emerging design strategies from both synthetic biology and materials science perspectives. Finally, we discuss the positive impacts of living materials on promoting sustainability and key future research directions.

“…The proposed important reactions in microbial hybrid photosynthesis include water splitting, H 2 supply, CO 2 reduction reactions, and ammonia synthesis. [ 2 ] In addition, there are two pathways for CO 2 reduction reactions. In one pathway, CO 2 is first reduced to CO, methanol, or formate by photo‐ or electro‐catalysts, and then utilized by microbes to synthesize carbon fuels.…”

Microbial hybrid photosynthesis has attracted great interests in recent years since it integrates the advantages of natural and artificial photosynthesis for solar‐to‐chemical conversion. Coupling a light source with scanning electrochemical microscopy, scanning photoelectrochemical microscopy (SPECM) shows great potential in investigating the interfacial reactions of microbial hybrid photosynthesis. In this Emerging Topic, the potential roles of SPECM in revealing biotic–abiotic interfacial electron transfer mechanisms and calculating electrode process kinetics are proposed for hybrid photosynthesis, and this will also inspire the applications of SPECM in the fields including biomineralization, photocatalytic‐biodegradation and microbial photoelectrochemical systems.

“…The semiartificial photosynthesis, which integrates an artificial photosensitizer with a biocatalyst, shows great potential in converting solar energy into specific chemicals. − Typically, upon irradiation, photoexcited electrons from the photosensitizer are used by a nonphototrophic microorganism to produce the target metabolites . The systems have been demonstrated to produce diverse chemicals, such as hydrogen, acetate, and methane, and remove pollutants or recover high-energy chemicals from wastewater. − For example, a cadmium sulfide-photosensitized Thiobacillus denitrificans (CdS/T.…”

Semiartificial photosynthesis shows great potential in solar energy conversion and environmental application. However, the rate-limiting step of photoelectron transfer at the biomaterial interface results in an unsatisfactory quantum yield (QY, typically lower than 3%). Here, an anthraquinone molecule, which has dual roles of microbial photosensitizer and capacitor, was demonstrated to negotiate the interface photoelectron transfer via decoupling the photochemical reaction with a microbial dark reaction. In a model system, anthraquinone-2-sulfonate (AQS)-photosensitized Thiobacillus denitrificans, a maximum QY of solar-to-nitrous oxide (N2O) of 96.2% was achieved, which is the highest among the semiartificial photosynthesis systems. Moreover, the conversion of nitrate into N2O was almost 100%, indicating the excellent selectivity in nitrate reduction. The capacitive property of AQS resulted in 82–89% of photoelectrons released at dark and enhanced 5.6–9.4 times the conversion of solar-to-N2O. Kinetics investigation revealed a zero-order- and first-order- reaction kinetics of N2O production in the dark (reductive AQS-mediated electron transfer) and under light (direct photoelectron transfer), respectively. This work is the first study to demonstrate the role of AQS in photosensitizing a microorganism and provides a simple and highly selective approach to produce N2O from nitrate-polluted wastewater and a strategy for the efficient conversion of solar-to-chemical by a semiartificial photosynthesis system.
