“…Research showed that EET might act as an electron relay to link semiconductor-mediated extracellular redox reaction with bacteria-mediated intracellular redox reaction. 2 Shewanella oneidensis MR-1 is a model EAB with bidirectional EET ability, 15 which could be used for extracellular reduction of various pollutants including azo dye, 16 dimethyl sulfoxide 17 and Cr( vi ). 18 However, the EET rate of S. oneidensis MR-1 is low, which severely restricts its reduction ability to degrade pollutants.…”

“…1 Inspired by this, in order to achieve low-carbon wastewater treatment, researchers attempted to introduce semiconductors into wastewater treatment to enhance traditional biological treatment with the assistance of renewable solar energy in recent years. 2 However, the function and ultimate efficiency of bacteria–semiconductor systems remain unsatisfactory for application, mainly because of the lack of understanding of bacteria–semiconductor interaction.…”

“…Recently, photocatalytic materials and microbes are intimately combined together to form the so-called photocatalytic material-microbe hybrid (PMH) system (Du et al, 2020). In 2016, the PMH system is firstly built by Professor Peidong Yang' group in Berkeley, University of California, to realize solar-tochemical production (Sakimoto et al, 2016).…”

Environmental pollution has become one of the most urgent global issues that we have to face now. Searching new technologies to solve environmental issues is of great significance. By intimately coupling photocatalytic materials with microbes, the emerging photocatalytic material–microbe hybrid (PMH) system takes advantages of the high-efficiency, broad-spectrum light capture capability of the photocatalytic material and the selectivity of microbial enzymatic catalysis to efficiently convert solar energy into chemical energy. The PMH system is originally applied for the solar-to-chemical production. Interestingly, recent studies demonstrate that this system also has great potential in treating environmental contaminations. The photogenerated electrons produced by the PMH system can reductively decompose organic pollutants with oxidative nature (e.g., refractory azo dyes) under anaerobic circumstances. Moreover, based on the redox reactions occurring on the surface of photocatalysts and the enzymatic reactions in microbes, the PMH system can convert the valences of multiple heavy metal ions into less toxic or even nontoxic status simultaneously. In this review, we introduce the recent advances of using the PMH system in treating environmental pollutions and compare this system with another similar system, the traditional intimately coupled photocatalysis and biodegradation (ICPB) system. Finally, the current challenges and future directions in this field are discussed as well.

With the increasing awareness of sustainable development, energy and environment are becoming two of the most important issues of concern to the world today. Whole-cellbased photosynthetic biohybrid systems (PBSs), an emerging interdisciplinary field, are considered as attractive biosynthetic platforms with great prospects in energy and environment, combining the superiorities of semiconductor materials with high energy conversion efficiency and living cells with distin-guished biosynthetic capacity. This review presents a systematic discussion on the synthesis strategies of whole-cell-based PBSs that demonstrate a promising potential for applications in sustainable solar-to-chemical conversion, including light-facilitated carbon dioxide reduction and biohydrogen production. In the end, the explicit perspectives on the challenges and future directions in this burgeoning field are discussed.
