Abstract
Geobacter sulfurreducens DL1 is a metal-reducing dissimilatory bacterium frequently used to produce electricity in bioelectrochemical systems (BES). The biofilm formed on electrodes is one of the most important factors for efficient electron transfer; this is possible due to the production of type IV pili and c-type cytochromes that allow it to carry out extracellular electron transfer (EET) to final acceptors. In this study, we analyzed the biofilm formed on different support materials (glass, hematite (Fe2O3) on glass, fluorine-doped tin oxide (FTO) semiconductor glass, Fe2O3 on FTO, graphite, and stainless steel) by G. sulfurreducens DL1 (WT) and GSU1771-deficient strain mutant (Δgsu1771). GSU1771 is a transcriptional regulator that controls the expression of several genes involved in electron transfer. Different approaches and experimental tests were carried out with the biofilms grown on the different support materials including structure analysis by confocal laser scanning microscopy (CLSM), characterization of electrochemical activity, and quantification of relative gene expression by RT-qPCR. The gene expression of selected genes involved in EET was analyzed, observing an overexpression of pgcA, omcS, omcM, and omcF from Δgsu1771 biofilms compared to those from WT, also the overexpression of the epsH gene, which is involved in exopolysaccharide synthesis. Although we observed that for the Δgsu1771 mutant strain, the associated redox processes are similar to the WT strain, and more current is produced, we think that this could be associated with a higher relative expression of certain genes involved in EET and in the production of exopolysaccharides despite the chemical environment where the biofilm develops. This study supports that G. sulfurreducens is capable of adapting to the electrochemical environment where it grows.

Abstract
Electrosynthesis is a popular, environmentally friendly substitute for conventional organic methods. It involves using charge transfer to stimulate chemical reactions through the application of a potential or current between two electrodes. In addition to electrode materials and the type of reactor employed, the strategies for controlling potential and current have an impact on the yields, product distribution, and reaction mechanism. In this Review, recent advances related to electroanalysis applied in electrosynthesis were discussed. The first part of this study acts as a guide that emphasizes the foundations of electrosynthesis. These essentials include instrumentation, electrode selection, cell design, and electrosynthesis methodologies. Then, advances in electroanalytical techniques applied in organic, enzymatic, and microbial electrosynthesis are illustrated with specific cases studied in recent literature. To conclude, a discussion of future possibilities that intend to advance the academic and industrial areas is presented.

Abstract
The metal-based current collector has been adopted as an essential component of cathodes for electron delivery in microbial electrosynthesis (MES) cells, while the effect of its corrosion on biofilm development and electromethanogenesis activity was overlooked. In this study, the corrosion of the Fe-based current collector was identified to in situ decorate cathode naturally which substantially boosted the performance of CO2 electromethanogenesis in terms of taking over two-thirds less time starting up MES and increasing the CH4 production rate by 3.5 times. Despite the low concentration of Fe (0.13 at%), the electrochemical analysis indicated that it was possible for these Fe deposits to act as electron shuttles and catalysts for H2 production to benefit methanogenesis. The Fe aggregates weakened the dependence of methanogens on electroactive bacteria (EABs) to conduct methanogenesis via interspecies electron transfer as the proportion of EABs on Bio FeCF (with Fe current collector, where CF is carbon felt) was only 25.5% of that on Bio CF (without Fe current collector). On the contrary, the abundance of genes encoding the proteins to uptake extracellular electrons of methanogens on Bio FeCF was 2.3 times higher than that on Bio CF. The enhanced energy transfer maintained high amounts of methanogens and live microorganisms. This study comprehensively explored the multiple roles of Fe-based current collectors in enhancing CO2 electromethanogenesis.

Abstract
This review presents a comprehensive summary of the material-microorganism interface in microbial hybrid electrocatalysis systems. Microbial hybrid electrocatalysis has been developed to combine the advantages of inorganic electrocatalysis and microbial catalysis. However, electron transfer at the interfaces between microorganisms and materials is a very critical issue that affects the efficiency of the system. Therefore, this review focuses on the electron transfer at the material-microorganism interface and the strategies for building efficient microorganism and material interfaces. We begin with a brief introduction of the electron transfer mechanism in both the bioanode and biocathode of bioelectrochemical systems to understand the material-microorganism interface. Next, we summarise the strategies for constructing efficient material-microorganism interfaces including material design and modification and bacterial engineering. We also discuss emerging studies on the bio-inorganic hybrid electrocatalysis system. Understanding the interface between electrode/active materials and the microorganisms, especially the electron transfer processes, could help to drive the evolution of material-microorganism hybrid electrocatalysis systems towards maturity.

Modular configurations of living biomaterials incorporating nano-based artificial mediators and synthetic biology to improve bioelectrocatalytic performance: A review.

Abstract
Currently, the industrial application of bioelectrochemical systems (BESs) that are incubated with natural electrochemically active microbes (EABs) is limited due to inefficient extracellular electron transfer (EET) by natural EABs. Notably, recent studies have identified several novel living biomaterials comprising highly efficient electron transfer systems allowing unparalleled proficiency of energy conversion. Introduction of these biomaterials into BESs could fundamentally increase their utilization for a wide range of applications. This review provides a comprehensive assessment of recent advancements in the design of living biomaterials that can be exploited to enhance bioelectrocatalytic performance. Further, modular configurations of abiotic and biotic components promise a powerful enhancement through integration of nano-based artificial mediators and synthetic biology. Herein, recent advancements in BESs are synthesized and assessed, including heterojunctions between conductive nanomaterials and EABs, in-situ hybrid self-assembly of EABs and nano-sized semiconductors, cytoprotection in biohybrids, synthetic biological modifications of EABs and electroactive biofilms. Since living biomaterials comprise a broad range of disciplines, such as molecular biology, electrochemistry and material sciences, full integration of technological advances applied in an interdisciplinary framework will greatly enhance/advance the utility and novelty of BESs. Overall, emerging fundamental knowledge concerning living biomaterials provides a powerful opportunity to markedly boost EET efficiency and facilitate the industrial application of BESs to meet global sustainability challenges/goals.

Abstract
Hematite has been proven to be an excellent material for enhancing extracellular electron transfer (EET) in microbial bioelectrochemical systems (BESs). However, the effect of hematite with different exposed facets on microbial EET remains unclear. Here, we synthesized two types of hematite nanoparticles with high {100} and {001} facet exposure (Hem_{100} and Hem_{001}), respectively, which were coated on ITO electrode to stimulate the microbial EET in the BESs. The results showed that the maximum biocurrent density of commercial hematite nanoparticles (Hem_NPs), Hem_{100} and Hem_{001} electrodes reached 73.33 ± 5.68, 129.33 ± 9.12 and 287.00 ± 19.89 μA cm-2 from three replicates of each treatment, respectively. The current generation achieved from the Hem_{001} electrode was nearly 199-times higher than that of the blank ITO electrode (1.44 ± 0.10 μA cm-2). The electrochemical measurements showed that the lowest charge transfer resistance (Rct) was observed for the Hem_{001}, and the promoted biofilm formation and EPS secretion on the Hem_{001} electrode were also revealed, which could contribute the high performance of this electrode. Moreover, metagenomic analysis revealed that Hem_{001} might facilitate the microbial EET by stimulating the expression of genes related to cytochrome c and conductive nanowires. This study not only provides a new strategy to enhance microbial electrogenesis but also expands the knowledge of the effect of facet on microbial EET, helping to develop more efficient electrode materials in the future.

Abstract
Microbial fuel cells (MFCs) are recognized as a future technology with a unique ability to exploit metabolic activities of living microorganisms for simultaneous conversion of chemical energy into electrical energy. This technology holds the promise to offer sustained innovations and continuous development towards many different applications and value-added production that extends beyond electricity generation, such as water desalination, wastewater treatment, heavy metal removal, bio-hydrogen production, volatile fatty acid production and biosensors. Despite these advantages, MFCs still face technical challenges in terms of low power and current density, limiting their use to powering only small-scale devices. Description of some of these challenges and their proposed solutions is demanded if MFCs are applied on a large or commercial scale. On the other hand, the slow oxygen reduction process (ORR) in the cathodic compartment is a major roadblock in the commercialization of fuel cells for energy conversion. Thus, the scope of this review article addresses the main technical challenges of MFC operation and provides different practical approaches based on different attempts reported over the years. Sustainable operation requires addressing key MFC-bottleneck issues. Enhancing extracellular electron transfer is the key to elevated MFC performance.![]()

Abstract
In this work, a novel three-chamber modular plant microbial fuel cell (PMFC) was designed and tested for long term sustainable generation of bioelecricity. The modular setup makes operation easy and hassle-free as placing every components, i.e., membranes, electrodes, and even changing the plants, becomes very convenient. The novel membrane assembly design combined with pre-activated electrodes with increased surface area helped promote biofilm growth and electrocatalytic activity on anode and cathode surface. The new design resulted in improved performance and stability of the PMFC system for long term usage with minimal maintenance. The use of composite membrane consisting of clay, bentonite, and fly ash mixture was used for the first time in PMFC research and proved to be an excellent alternative to existing expensive Nafion membranes. The power density and current density has increased up to 24.56 mW m-2 and 52 mA m-2 respectively, which is 63% increase in power production and is amongst the highest in PMFC research.

Abstract
The conversion of CO2 to value-added products powered with solar energy is an ideal solution to establishing a closed carbon cycle. Combining microorganisms with light-harvesting nanomaterials into photosynthetic biohybrid systems (PBSs) presents an approach to reaching this solution. Metabolic pathways precisely evolved for CO2 fixation selectively and reliably generate products. Nanomaterials harvest solar light and biocompatibly associate with microorganisms owing to similar lengths scales. Although this is a nascent field, a variety of approaches have been implemented encompassing different microorganisms and nanomaterials. To advance the field in an impactful manner, it is paramount to understand the molecular underpinnings of PBSs. In this perspective, we highlight studies inspecting charge uptake pathways and singularities in photosensitized cells. We discuss further analyses to more completely elucidate these constructs, and we focus on criteria to be met for designing photosensitizing nanomaterials. As a result, we advocate for the pairing of microorganisms with naturally occurring and highly biocompatible mineral-based semiconductor nanomaterials.

Abstract
Modifying the electrodes of microbial fuel cells (MFCs) with iron oxides can improve the bacterial attachment performances and electrocatalytic activities for energy conversion, which is of significance in the fabrication of MFCs. However, the conventional modification methods usually result in the aggregation of iron sites, producing the electrodes of poor qualities. Herein, we report a novel method for the modification of electrochemical electrodes to boost the anode performance of MFC. The Shewanella precursor adhered on carbon felt electrode was directly carbonized to form a bacteria-derived biological iron oxide/carbon (Bio-FeOx/C) nanocomposite catalyst. The large spatial separation between the bacteria, as well as those between the iron containing proteins in the bacteria, deliver a highly dispersed Bio-FeOx/C nanocomposite with good electrocatalytic activities. The excellent microbial attachment performance and electron transfer rate of the Bio-FeOx/C modified electrode significantly promote the transfer of produced electrons between bacteria and electrode. Accordingly, the MFC with the Bio-FeOx/C electrode exhibits the maximum power density of 797.0 mW m-2, much higher than that obtained with the conventional carbon felt anode (226.1 mW m-2). Our works have paved a new avenue to the conversion of the natural bacterial precursors into active iron oxide nanoparticles as the anode catalyst of MFCs. The high catalytic activity of the prepared Bio-FeOx endows it great application potentials in the construction of high-performance electrodes.

Bimetallic oxide MnFe 2O 4 modified carbon felt anode by drip coating: an effective approach enhancing power generation performance of microbial fuel cell. Bioprocess Biosyst Eng 2021; 44:1119-1130. [PMID: 33555380 DOI: 10.1007/s00449-021-02511-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Accepted: 01/05/2021] [Indexed: 10/22/2022]
Abstract
The anode electrode of microbial fuel cell (MFC) is the key component to determine its power generation performance because it is the habitat and electron transfer center of the electricity-producing microorganisms. Carbon-based anodes have been confirmed to improve MFC performance. Its large surface area, excellent conductivity and low cost make it very suitable for electrode materials used in MFC. However, the low biocompatibility and instability of common carbon-based materials restrict their practical application in MFC. In this work, a bimetal oxide MnFe2O4 was prepared and used to modify carbon felt anode by a simple drop coating method. The influence of the amount of MnFe2O4 material on the performance of MFC was systematically studied. The results showed that the power density of the carbon felt anode with a MnFe2O4 modified amount of 1 mg/cm2 increased by 66.9% compared with the unmodified anode. Meanwhile, the MFC cycle using MnFe2O4 modified anode was more stable. After 6 months of long-term operation, the power density reached 3836 mW/m2. The anode modified by MnFe2O4 has capacitance characteristics, good biocompatibility and fast electron transmission rate, which significantly improves the power generation performance of MFC. In addition, the use of a simple drop coating method to prepare electrodes can reduce the difficulty of electrode fabrication and the cost of MFC, laying a certain foundation for the industrialization of MFC.

Abstract
Dual chambered microbial fuel cells with Potassium dichromate (22 g/L, MFC-1) and tannery effluent waste water containing 26 mg/L (MFC-2), 5 mg/L (MFC-3) of Cr(VI) as catholyte, sweet lime waste inoculated by cowdung as anolyte and graphite electrodes were used to reduce toxic Cr(VI) to Cr(III) with simultaneous power generation. Cr (VI) in the cathode chamber reduced to Cr2O3 within 24 h. Complete reduction of Cr(VI) from tannery effluents by microbial fuel cell is noticed within 10 days. The 16 s rRNA sequencing studies demonstrated presence of Geobacter Metallireducens in mixed culture bacteria in anaerobic anode. The power density of the device is 396.7 mW/m2on day1which is 7.2 times higher than literature data of 55.5 mW/m2. The processes involved on the biofilm/electrolyte interface and graphite/electrolyte interface is studied by Electrochemical Impedance Spectroscopy. Electrochemical studies demonstrated the active growth of biofilm on anode which reduces charge transfer resistance from day 1 to day 25. The concentration of Cr(VI) reduced in the present studies are approximately 1000 times higher than those reported in the literature.

Abstract
Electron transfer kinetics of Shewanella loihica PV-4 at the up-growing TiO2 nanosheet (TiO2-NS) modified carbon paper (CP) electrode was investigated. The effect of TiO2-NSs, which speeds up the interfacial electron transfer of outer membrane c-type cytochromes (OMCs), was revealed for the first time. TiO2-NSs with a polar surface modified hydrophobic CP into super-hydrophilic TiO2-NS/CP. The favorable interaction between PV-4 and TiO2-NSs not only enhanced microbial adhesion, but also altered the redox nature of OMCs. The mid-point potential of OMCs at TiO2-NS/CP was shifted to a more negative potential, indicating a higher thermodynamic driving force for the protein to release electrons. Moreover, electron transfer from OMCs to TiO2-NSs was also benefited from the positive shift of flat-band potential Vfb owing to reduced pH at the electrode/microorganism interface, as well as good electrical conductivity of TiO2-NSs. As a result, the electron transfer rate constant ket of OMCs at the TiO2-NS/CP anode was about three times faster than that at the CP anode. The accelerated electron transfer kinetics as well as 15% increase of biomass together accounted for a 97% increase of the maximum output power density in the MFC. The result expanded our knowledge about the role of a designed TiO2 nanostructure in microbial electron transfer that can be applied in other bio-electrochemical systems.

Abstract
The role of red mud in the improvement of methanogenesis during sludge anaerobic digestion was innovatively investigated in this study. The results demonstrated that the addition of 20g/L red mud resulted in a 35.5% increase in methane accumulation. Red mud effectively promoted the hydrolysis-acidification of organic compounds in the sludge, which resulted in the increase of protein, polysaccharide, and VFAs by 5.1-94.5%. The activities of key enzymes were improved by 41.4-257.3%. Electrochemical measurements presented direct evidence that the electrical conductivity was significantly improved with red mud. More conductive magnetite was formed during the secondary mineralization after Fe(III) reduction by Fe (III)-reducing genes such as Clostridiaceae and Ruminococcaceae. The higher conductivity enhanced the electron transfer between the syntrophic bacteria (Geobacteraceae) and methanogens (Methanosaeta and Methanosarcina), and then improved the methanogenesis. This research provides a novel perspective on the synergism between sludge and red mud for methane production.

Abstract
A novel bi-component composite of porous self-assembled micro-/nanostructured Ni0.1Mn0.9O1.45 microellipsoids as high-performance anode electrocatalyst for microbial fuel cells (MFCs) is successfully synthesized via a simple coprecipitation reaction in microemulsion and calcination method in air atmosphere. The morphology and structural characterization indicate that the as-fabricated Ni0.1Mn0.9O1.45 product is consist of Mn2O3 and NiMn2O4 (n(Mn2O3): n(NiMn2O4) = 0.35: 0.1) and has a porous microellipsoidal morphology. The microellipsoids are compose of numerous layered micro-/nanostructured blocks and the special porous microellipsoids structure of Ni0.1Mn0.9O1.45 offers a large specific surface area for bacteria adhesion. The porous Ni0.1Mn0.9O1.45 microellipsoids as anode electrocatalyst for MFCs exhibits excellent electrocatalytic activity to promote the extracellular electron transfer (EET) between the anode and bacteria, hence improves the performance of MFC. The MFC equipped with Ni0.1Mn0.9O1.45/CF anode achieves a maximum power density of 1.39 ± 0.02Wm-2, is significantly higher than that of commercial carbon felt anode. This work proposes a new method for the synthesis of high-performance and environmentally friendly anode electrocatalyst for MFCs.

Abstract
Electrochemical parameters of bacterial cells Shewanella oneidensis MR-1 were investigated. For registration of the direct electron transfer between S. oneidensis MR-1 and electrode, bacterial cells were pretreated with didodecyldimethylammonium bromide (DDAB), a synthetic membrane-like substance of polycationic nature that exhibits membrane-loosening properties. Such pretreatment of S. oneidensis MR-1 allowed increasing the efficiency of extracellular electron transfer by the proteobacterium due to better availability of electroactive proteins for registration of electron transfer processes. The electroanalysis of bacterial cells S. oneidensis MR-1 under anaerobic conditions allows registering redox-active proteins and biomolecules in the range of potentials of-0.40,-0.16, and-0 V, which corresponds to flavohemoproteins, quinone derivatives, and c-type cytochromes of the external membrane of S. oneidensis MR-1 cells.

This study demonstrates the use of Liquid Crystal coated Polaroid Glass Electrode (LCPGE) material collected from disposed liquid-crystal display (LCD) computer monitor as electrodes in microbial fuel cell (MFC) for the simultaneous reduction/recovery of Cr(+6) from chromium wastewater. Fourier transform infrared spectrum (FT-IR) confirms the presence of NH2, CN, CO and OC and/or COC functional groups in LCPGE. An excellent electrochemical performance with distinct redox peaks were observed in cyclic voltammetry test (100 mV/s). The maximum current density of 110 mA/m(2) (10 mW/m(2)) was achieved by operating MFC in batch mode. At the cathode LCPGE (10.5 cm(2)) interface, toxic Cr(+6) ions readily accepted electrons and formed nontoxic Cr2O3 as confirmed by FT-IR and X-ray photoelectron spectroscopy analysis. Moreover, electrochemical impedance analysis shows that bacteria were readily attached to the surface of LCPGE (10.5 cm(2)) within 24 h in a Bioelectrochemical System (BES).
