A flavin-based extracellular electron transfer mechanism (EET) has recently been described for the gram-positive Listeria monocytogenes. The gram-positive, solvent producing Clostridium acetobutylicum is a known flavin producer. Since flavin secretion in C. acetobutylicum can be triggered by a low-iron environment, the interaction of iron with an electrochemical system as well as the consequences for flavin production are investigated. It is shown that iron adsorbs onto the electrode's surface in the form of iron phosphorus compounds but that this iron is still bioavailable. Moreover, a shift in the flavin spectrum of the supernatant from high flavin mononucleotide percentages of 59% to high riboflavin (43-45%) and flavin adenine dinucleotide (FAD, 40-48%) content can be seen by limiting or omitting the iron source from the culture medium. When additionally an electric potential of -600 mV vs. Ag/AgCl (saturated KCl) is applied, the same overall trend is obtained but an increase in flavin concentration and especially in the FAD share between 6 and 27% is observed. This study is a first hint that a flavin-based EET might also take place in solventogenic Clostridia and highlights the importance of further investigation of flavin production and their involvement in EET mechanisms in different species.

An adhesive conducting electrode material containing of graphite, biocompatible ion exchange polymer nafion(®) and commercial mesoporous TiO2 impregnated with horseradish peroxidase (HRP) is prepared and characterized by amperometric, UV-vis and N2 sorption methods. The factors influencing the performance of the resulting biosensor are studied in detail. The optimal electrode material consists of 45% graphite, 50% impregnated HRP-TiO2 and 5% nafion(®). The optimum conditions for H2O2 reduction are an applied potential of -0.3 V and 0.1 mM hydroquinone. Sensitivity and limit of detection in the optimum conditions are 1 A M(-1) cm(-2) and 1 µM correspondingly. The N2 sorption results show that the pore volume of TiO2 decreases sharply upon adsorption of HRP. The preparation process of the proposed enzyme electrode is straightforward and potentially can be used for preparation of carbon paste electrodes for bioelectrochemical detections.

Nitrogen (N) pollution in water has become a serious issue that cannot be ignored due to the harm posed by excessive nitrogen to environmental safety and human health; as such, N concentrations in water are strictly limited. The bioelectrochemical system (BES) is a new method to remove excessive N from water, and has attracted considerable attention. Compared with other methods, it is highly efficient and has low energy consumption. However, the BES has not been applied for N removal in practice due to lack of in-depth research on the mechanism and construction of high-performance electrodes, separators, and reactor configurations; this highlights a need to review and examine the efforts in this field. This paper provides a comprehensive review on the current BES research for N removal focusing on the reaction principles, reactor configurations, electrodes and separators, and treatment of actual wastewater; the corresponding performances in these realms are also discussed. Finally, the prospects for N removal in water using the BES are presented.

Emerging contaminants and their intermediate residue pose significant risks to human health and ecosystems due to their persistence in water and soil. The review explores the potential of photo-bioelectrochemical systems as a dual-function approach for the degradation of emerging contaminants while simultaneously generating bioenergy. Photo-bioelectrochemical systems integrate microbial metabolism with photocatalytic processes, utilizing solar energy to enhance electron transfer and promote the breakdown of toxic compounds. Recently, this technology has demonstrated improved removal rates of various emerging contaminants, including antibiotics and neonicotinoid pesticides, while producing valuable by-products such as hydrogen and methane through optimized operational conditions. Although studies have focused mainly on pharmaceuticals and dyes, applying these systems for pesticides remains underexplored. Algae-assisted photo-bioelectrochemical systems have been observed frequently in recent studies. This review synthesizes current research on the metabolic activity and biochemical pathways involved in the biodegradation of contaminants within photo-bioelectrochemical systems. It highlights the efficiency of these systems in converting harmful substances into less toxic by-products. It addresses challenges such as slow degradation rates compared to chemical methods and the need for enhanced extracellular electron transfer capabilities among microorganisms. Through optimized operational conditions, this paper aims to provide a comprehensive understanding of photo-bioelectrochemical systems' performance and to propose future research directions for optimizing these systems in real-world applications. In conclusion, this work underscores the promise of photo-bioelectrochemical systems as a sustainable solution for wastewater treatment and environmental remediation.

Biohythane, a balanced mixture of 10%-30% v/v of hydrogen and 70%-90% v/v of methane, could be the backbone of an all-purpose future energy supply. Recently, bioelectrochemical systems (BES) became a new sensation among environmental biotechnology processes with the potential to sustainably generate biohythane. Therefore, to unleash its full potential for scaling up, researchers are consistently improving microbial metabolic pathways, novel reactors, and electrode designs. This review presents a detailed analysis of recently discovered fundamental mechanisms and science and engineering intervention of different strategies to improve the biohythane composition and production rate from BES. However, several milestones are to be achieved, for instance, improving electrode kinetics using efficient catalysts, engineered microbial communities, and improved reactor configurations, for commercializing this sustainable technology. Thus, a future perspective section is included to recommend novel research lines, mainly focusing on the microbial communities and the efficient electrocatalysts, to enhance reactor performance.

The aim of this study was to investigate the feasibility of sulfate removal and elemental sulfur (S 0 ) recovery in the single-chamber bioelectrochemical system (S-BES). The performance of S-BES was compared with that of dual-chamber bioelectrochemical system (D-BES). The S-BES was constructed with graphite felt as the anode and graphite brush as the cathode. The D-BES was constructed with proton exchange membrane as the separator between anode and cathode chambers. With an applied voltage of 1.0 V and 1 g/L acetate as the substrate, the S-BES and D-BES were tested by feeding with 480 mg/L SO 4 2- in the phosphate buffer. Results showed that the maximum current density of 37.6 ± 4.5 mA/m 3 was reached in the S-BES, which was higher than that in the D-BES (i.e., 22.2 ± 2.6 mA/m 3 ). The SO 4 2- removal was much higher in the S-BES than in the D-BES (99.5% vs. 57.2%). In the effluent and the electrodes of S-BES, S 0 was identified with Raman and X- Ray diffraction analyses. The S 0 recovery on the anode was 13.7 times of that on the cathode of S-BES, indicating that S 0 was mainly produced on the anode. The measured total S 0 recovery reached 67.5% in the S-BES. High relative abundance of Desulfurella (47.1%) and Geobacter (26.1%) dominated the community in the anode biofilm of S-BES. The excellent performance of S-BES may be attributed to the neutral pH in the solution and the synergistic reaction between the anode and cathode. Results from this study should be useful to enhance the S-BES applications in treating wastewater containing sulfate.

In this study, silver nanoparticles modified choline chloride functionalized graphene oxide (AgNPs-ChCl-GO) was synthesized using sonochemical method and utilized as a bioelectrochemical sensor for detection of celecoxib (CEL). The characterization studies were ultimately performed in order to acheive a more complete understanding of the morphological and structural features of the AgNPs-ChCl-GO using different techniques including FT-IR, AFM, FE-SEM, EDX, and XRD. AgNPs-ChCl-GO demonstrated a significant improvement in the reduction activity of CEL due to the enhancement in the current response compared to the bare carbon paste electrode (CPE). The optimum experimental conditions, were optimized using central composite design (CCD) methodology. The differential pulse voltammetry (DPVs) showed an expanded linear dynamic ranges of 9.6 × 10 -9 -7.4 × 10 -7  M for celecoxib in Britton-Robinson buffer in pH 5.0 with. LOD (S/N = 3) and LOQ (S/N = 10) were obtained 2.51 × 10 -9  M and 6.58 × 10 -9  M respectively. AgNPs-ChCl-GO-carbon paste electrode exhibited suitable properties and high accuracy determination of celecoxib in the human plasma sample.

The application of graphene (Gr) to microbial fuel cells (MFCs) and microbial electrolysis cell (MECs) is considered a very promising approach in terms of enhancing their performance. The superior Gr properties of high electrical and thermal conductivities, along with: superior specific surface area, high electron mobility, and mechanical strength, are the key features that endorse this. Factors impeding the advancement of a microbial fuel cell into commercialization involve primarily the cost of their components, and their production on a small scale. Gr with such outstanding characteristics can help mitigate these challenges, when used as electrode material. The application of Gr as an anode material improves the efficiency of electron transfer and bacterial attachment. When used as a cathode material, it supports the oxygen reduction reaction. This investigation, presents a thorough analysis of the feasibility of Gr as an electrode material in both MFC and MEC applications - based on experimental results from the investigation. Current technological advancements in the implementation of Gr in MFC and MEC are also highlighted in this review.
