Semiconductor-bacterial hybrid systems have been shown to be effective for photochemical conversion. The combination of two systems delineates the light absorption from the catalytic ability, wherein a semiconductor absorbs light, generating an electron−hole pair, followed by the transfer of photogenerated charges to catalytically active bacteria that assume the roles of carrying out redox reactions. The halide perovskite materials possess excellent optoelectronic properties and, if they exhibit biocompatibility with microorganisms, shall provide an opportunity to carry out environmentally important redox reactions including carbon dioxide conversion to value added products. In this work, we report the biocompatibility of panchromatic visible light absorption and stable vacancy ordered halide perovskite (VOP), Cs 2 PtX 6 (X = halide) with Shewanella oneidensis MR-1 nonphotosynthetic bacterium. This microbe is shown to grow in culture media containing VOP, and the growth rate is found to be unaffected by the presence of semiconductor media. Although Shewanella oneidensis MR-1 is a well-known metal-reducing bacteria, in this work, we find that the vacancy ordered perovskite materials remain intact with this bacterium. With constraint-based metabolic modeling, we report that this biohybrid system shall potentially be used for solar energy conversion of water and carbon dioxide to hydrogen and formate, respectively.

Heavy metal removal and simultaneous energy production were studied using a dual chambered Microbial Fuel Cell inoculated with Shewanella oneidensis MR‐1 in the anode. Synthetic wastewater was prepared with Cu (II), Mg (II), Mn (II), Zn (II), Na, and Phenol based on desalter effluent from refinery processes at different metal concentrations. In this study, a maximum open‐circuit voltage of 517.6 mV was reached at Conc. 5 with wastewater in the anode chamber, and 127.7 mV at Conc. 3 was produced with synthetic wastewater in the cathode chamber. Moreover, μ at Conc. 5 was 0.1133 h−1, demonstrating bacterial growth under metal and phenol concentrations. The highest metal removal in the anode for Cu (II), Mg (II), Mn (II), Zn (II), and Na was 93%, 85%, 93%, 88%, and 36%, respectively. In the cathode chamber the removal of Cu (II), Mg (II), Mn (II), Zn (II), and Na was 98%, 49%, 57%, 59%, and 36%, respectively. During the operation in the anode, SEM images showed that the bacterial nanowires are formed in response to toxic and anaerobic environments which contribute to the bacterial growth. These nanowires increased the metal removal and the voltage production as a consequence of a higher electron rate from the anode to the cathode due to the higher extracellular membrane surface area. S. oneidensis is a bacterium with metal‐reducing characteristics, and it is suitable for metal removal and electron transport from carbon sources, demonstrated in voltage production with microbial fuel cells.

“…Shewanella oneidensis MR-1, one of the most well-studied exoelectrogens, showed great promise in BESs as core biocatalysts. − The EET mechanism of S. oneidensis MR-1 has been extensively studied and elucidated, including contact-based direct electron transfer (DET) via a number of conductive outer-membrane c-cytochromes. − and indirect electron transport (IET) mediated by soluble electron shuttles. − Electrons generated by substrate oxidation were stored in the reduced form of nicotinamide adenine dinucleotide (NADH), which is the major releasable intracellular electron carrier; then, the electrons are transferred to extracellular electron acceptors via EET pathways. − Efforts toward synthetic biological strategies, , such as the de novo synthesis of intracellular NAD + and the acceleration of NADH regeneration, have been developed to enhance the intracellular releasable electron pool and the EET rate of S. oneidensis.…”

Modular Engineering Strategy to Redirect Electron Flux into the Electron-Transfer Chain for Enhancing Extracellular Electron Transfer in Shewanella oneidensis

Efficient extracellular electron transfer (EET) of exoelectrogens is critical for practical applications of various bioelectrochemical systems. However, the low efficiency of electron transfer remains a major bottleneck. In this study, a modular engineering strategy, including broadening the sources of the intracellular electron pool, enhancing intracellular nicotinamide adenine dinucleotide (NADH) regeneration, and promoting electron release from electron pools, was developed to redirect electron flux into the electron transfer chain in Shewanella oneidensis MR-1. Among them, four genes include gene SO1522 encoding a lactate transporter for broadening the sources of the intracellular electron pool, gene gapA encoding a glyceraldehyde-3-phosphate dehydrogenase and gene mdh encoding a malate dehydrogenase in the central carbon metabolism for enhancing intracellular NADH regeneration, and gene ndh encoding NADH dehydrogenase on the inner membrane for releasing electrons from intracellular electron pools into the electron-transport chain. Upon assembly of the four genes, electron flux was directly redirected from the electron donor to the electron-transfer chain, achieving 62% increase in intracellular NADH levels, which resulted in a 3.5-fold enhancement in the power density from 59.5 ± 3.2 mW/m2 (wild type) to 270.0 ± 12.7 mW/m2 (recombinant strain). This study confirmed that redirecting electron flux from the electron donor to the electron-transfer chain is a viable approach to enhance the EET rate of S. oneidensis.
