“…An additional aspect to consider about membrane separators used in MFC is the operating stability. For instance, reliable membrane separators should withstand chemical as well as biological fouling, which presents a threat, especially in the long-term [26,27]. Such impacts may notably alter the initial (physico-chemical) features of the membrane and as a result, cyclic regeneration or even replacement may be inevitable for keeping the MFC in a good condition.…”

“…These rely on the blending of various ILs and organic polymers, resulting in a polymer-inclusion membrane, and can be regarded as a possible way forward [36][37][38]. On the other hand, just like in most (filtration) processes where a membrane is employed, chemical and biological fouling of the membrane installed in the bioelectrochemical system is a real threat [26]. Therefore, over time, the deposition of chemical agents, substances, and microbes can be expected.…”

Membrane separators are key elements of microbial fuel cells (MFCs), especially of those constructed in a dual-chamber configuration. Until now, membranes made of Nafion have been applied the most widely to set-up MFCs. However, there is a broader agreement in the literature that Nafion is expensive and in many cases, does not meet the actual (mainly mass transfer-specific) requirements demanded by the process and users. Driven by these issues, there has been notable progress in the development of alternative materials for membrane fabrication, among which those relying on the deployment of ionic liquids are emerging. In this review, the background of and recent advances in ionic liquid-containing separators, particularly supported ionic liquid membranes (SILMs), designed for MFC applications are addressed and evaluated. After an assessment of the basic criteria to be fulfilled by membranes in MFCs, experiences with SILMs will be outlined, along with important aspects of transport processes. Finally, a comparison with the literature is presented to elaborate on how MFCs installed with SILM perform relative to similar systems assembled with other, e.g., Nafion, membranes.

“…This process is known as the alkaline lysis and was used by Pasternak et al (2016) for improving the performance of deteriorated cathodes (Figure 1B). The biofouling problem of cathodes in BES has been widely reported and leads to the significant decrease of MFC performance (Al Lawati et al, 2019;Noori et al, 2019;Rossi et al, 2019b). In the above mentioned study, the authors recorded nearly 91% drop of power, which clearly resulted from the growth of the biofilm at the graphite-based cathode of the ceramic MFCs.…”

Bioelectrochemical systems (BESs) are ruled by a complex combination of biological and abiotic factors. The interplay of these factors determines the overall efficiency of BES in generating electricity and treating waste. The recent progress in bioelectrochemistry of BESs and electrobiotechnology exposed an important group of compounds, which have a significant contribution to operation and efficiency: surface-active agents, also termed surfactants. Implementation of the interfacial science led to determining several effects of synthetic and natural surfactants on BESs operation. In high pH, these amphiphilic compounds prevent the cathode electrodes from biodeterioration. Through solubilization, their presence leads to increased catabolism of hydrophobic compounds. They interfere with the surface of the electrodes leading to improved biofilm formation, while affecting its microarchitecture and composition. Furthermore, they may act as quorum sensing activators and induce the synthesis of electron shuttles produced by electroactive bacteria. On the other hand, the bioelectrochemical activity can be tailored for new, improved biosurfactant production processes. Herein, the most recent knowledge on the effects of these promising compounds in BESs is discussed.

“…Microbial electrosynthesis (MES) of valuable organic compounds from CO 2 as feedstock is highly promising novel technology, which is gaining great attention among researchers . MES systems are type of bioelectrochemical system (BES) which uses two reverse polar electrode as anode and cathode placed in either two separated chamber or in the same chamber . Chemolitho‐autotrophic microbes embedded in the electroactive biofilm on cathode utilizes CO 2 as sole carbon substrate and electron as reducing equivalent directly or mediated via H 2 or formic acid to produce biochemical or biofuels .…”

Microbial electrosynthesis (MES) can efficiently convert CO2 into valuable chemicals. A biocathode, which plays central role in MES process, is expected to have very high surface area and catalytic activity to derive the cathodic reaction flawlessly. In this study, a highly porous bimetallic FexMnOy (x=1, 2 and y=3, 4) microsphere was synthesized and applied as cathode catalyst in a single chamber MES. MES having FexMnOy exhibited higher net acetate production rate (204 mM/m2d) and coulombic efficiency (58 %) than the MES without catalyst (180 mM/m2d and 34 %). The excellent performance of MES with FexMnOy was attributed to the high Brunauer‐Emmett‐Teller (BET) surface area (around 278 m2/g) with rough surface and efficient electron transfer from cathode to microorganism promoted by FexMnOy complex. The cathode with FexMnOy reduced charge transfer resistance by ∼70 % and enhanced the exchange current density by 7.2‐times compared to plain cathode. This study suggests that FexMnOy can be used as the highly efficient and low‐cost catalyst on cathode of scaled up MESs.
