“…Halophilic sediments such as CJ have shown in previous works their efficiency in designing halotolerant bioanode able to degrade azo dyes in textile wastewater with more than 90% of COD removal rate (Askri et al, 2020). Moreover Pugazhendi et al (2020) reached a COD removal efficiency of up to 89% when used halophilic microorganisms to treat seafood industrial wastewater. Similarly, Feng et al (2015) reported enhanced removal of recalcitrant p-Fluoronitrobenzene when a MEC was operated at highly saline conditions.…”

This study investigated for the first time the performance of microbial halotolerant bioanodes designed from two Tunisian Hypersaline Sediments (THS) for simultaneous electrostimulated biodegradation of synthetic fruit packaging wastewater containing thiabendazole (TBZ), and recovery of an anodic current signal. Halotolerant bioanodes formation has been conducted on 6 cm2 carbon felt electrodes polarized at −0.1Vvs Saturated Calomel Electrode (SCE), inoculated with 80% (v:v) of synthetic wastewater containing 50 ppm of irradiated or not irradiated TBZ and 20% (v:v) of THS for a period of 7 days. Microbial bioanodes, and the corresponding anolytes, i.e., synthetic wastewater, were studied comparatively by electrochemical, microscopic, spectroscopic, molecular and microbial ecology tools. Despite the low maximum current densities recorded in the 50 ppm TBZ runs (3.66 mA/m2), more than 80% of the TBZ was degraded when non-irradiated TBZ (nTBZ) was used as the sole carbon energy by the microorganisms. Nevertheless, the degradation in the presence of irradiated TBZ (iTBZ) was greatly reduced by increasing the irradiation dose with maximum current density of 0.95 mA/m2 and a degradation rate less than 50% of iTBZ. In addition, chemical changes were observed in TBZ as a result of gamma irradiation and bioelectrochemical degradation. FT-IR and UV-Vis techniques confirmed the degradation of TBZ structural bonds producing novel functional groups. Culture-dependent approach and 16S ribosomal RNA sequencing demonstrated that bacterial community of halotolerant bioanodes formed with nTBZ were dominated by Proteobacteria (75%) and Firmicutes (25%). At species level, enrichment of Halomonas smyrnensis, Halomonas halophila, Halomonas salina, Halomonasor ganivorans and Halomonas koreensis on carbon felt electrodes were correlated with maximal current production and nTBZ degradation. As a result, THS halotolerant bacteria, and specifically those from Chott El Djerid (CJ) site certainly have well established application for the electrostimulated microbial biodegradation of fungicide in the real fruit and vegetable processing industries.

Microbial Fuel Cell as a Future Energy Source: A Review of Its Development, Design, Power Generation, and Voltage Reversal Control Mechanism

2022

Microbial fuel cell (MFC) is a promising technology that uses microorganisms to generate electrical energy from chemical energy. However, ultra-low-power production and high-cost material became significant drawbacks in MFC development. Therefore, various methods are proposed by researchers to increase the output power of MFC. Among them, stacking up multiple cells in a series is suggested as one of the most promising methods to generate high power in MFC. However, the voltage reversal (VR) becomes an issue that limits electrical power generation in the stacked MFC. Thus, this study investigates and discusses the actual cause of the voltage reversal phenomenon in series stacked MFC from the perspective of electron and proton transfer mechanisms. This paper also discusses electronic control methods used to eliminate VR and the challenges in MFC development. Furthermore, this review also explains the brief evolution of MFC development stages and the factor influencing the performance of the MFC.

Bioenergy Potential of Albumin, Acetic Acid, Sucrose, and Blood in Microbial Fuel Cells Treating Synthetic Wastewater

et al. 2021

Microbial fuel cells (MFCs) are a recent biotechnology that can simultaneously produce electricity and treat wastewater. As the nature of industrial wastewater is very complex, and it may contain a variety of substrates—such as carbohydrates, proteins, lipids, etc.—previous investigations dealt with treatment of individual pollutants in MFCs; the potential of acetic acid, sucrose, albumin, blood, and their mixture has rarely been reported. Hence, the current investigation explored the contribution of each substrate, both separately and in mixture. The voltage generation potential, current, and power density of five different substrates—namely, acetic acid, sucrose, albumin, blood, and a mixture of all of the substrates—was tested in a dual-chambered, anaerobic MFC operated at 35 °C. The reaction time of the anaerobic batch mode MFC was 24 h, and each substrate was treated for 7 runs under the same conditions. The dual-chambered MFC consisted of anode and cathode chambers; the anode chamber contained the biocatalyst (sludge), while the cathode chamber contained the oxidizing material (KMnO4). The maximum voltage of 769 mV was generated by acetic acid, while its corresponding values of current and power density were 7.69 mA and 347.85 mW, respectively. Similarly, being a simple and readily oxidizable substrate, acetic acid exhibited the highest COD removal efficiency (85%) and highest Coulombic efficiency (72%) per run. The anode accepted the highest number of electrons (0.078 mmol/L) when acetic acid was used as a substrate. The voltage, current, and power density generated were found to be directly proportional to COD concentration. The least voltage (61 mV), current (0.61 mA), and power density (2.18 mW) were observed when blood was treated in the MFC. Further research should be focused on testing the interaction of two or more substrates simultaneously in the MFC.
