“…Ni-foam F I G U R E 3 Solar -MEC system electron transfer mechanism representing Z scheme of photosynthesis was selected as the anode because of its large surface area, excellent biocompatibility to facilitate bacterial attachment growth, decent corrosion resistance, and high electronic conductivity. 18,47 The control produced a negligible quantity of methane by the end of the 13th day. Therefore, it was not further investigated.…”

“…In the meantime, the exoelectrogenic microorganisms, such as G sulfurreducens, present in the bio-anode of MEC, oxidize the organic substrate available, and produce H + ions and electrons. 20,46 The generated electrons were moved toward the p-type region of the solar cell to recombine with the hole and make electron-hole pair, making the circuit complete. The cycle continues as long as the solar energy lightens the polycrystalline silicon solar cell and the organic substrate is oxidized.…”

[18][19][20] The directional migration of these charged particles toward the cathode is supported by the applied voltage, where they combine to produce bio-hydrogen. 13 Organic wastes, synthetic effluents, and organic wastewaters can be effectively used as substrates in the MEC.…”

The microbial electrolysis cell (MEC) is an emerging technology for bioenergy production using organic wastewater. Normally, a preassimilated bio-anode is utilized by the MEC to break down the organic content, but the formation and assimilation of microbial community at the anode surface is a time-consuming process. This study utilized a novel unassimilated Ni-foam anode for the first time in solar-powered MEC for bioenergy production. Synthetic dairy manure wastewater (SDMW) was used both as substrate and an inoculum in the solarpowered tubular MEC. The impacts of the exposed surface area of the bio-anode on bioenergy production were evaluated by utilizing two different separation techniques (rate-limited bio-anode -MEC and fully exposed bio-anode -MEC). The former technique achieves a maximum methane production rate of 30.35 ± 0.03 mL/L, 14.2% more than that achieved by the later mentioned technique (26.4 ± 0.05 mL/L). Hydrogen production was approximately 800 ± 5 mm 3 in both experimentations. The maximum generated current in the rate limited bioanode -MEC was 35.5 mA. Scanning electron microscope images confirmed the formation of rod-shaped along with round-shaped microbial communities on the anode surface, and, interestingly, round-shaped bacteria were also grown on the cathode surface. The bioenergy (H 2 and CH 4 ) produced using SDMW within first 13 days of operation, along with the formation of a microbial community, was a significant success in this area and has opened up many research opportunities for producing instant bioenergy from organic waste.

Summary Microbial electrolysis cells (MECs) are one of the most promising innovation amongst bio‐electrochemical systems for biohydrogen production. A wide variety of wastewaters and organic wastes that is, sodium acetate, glucose, glycerol, domestic wastewater, sugar industries effluent, food processing wastewater, industrial wastewater, etc. can be utilized as substrates in MEC. The objective of this comprehensive review is to study the effects of reactor configuration, electrode materials, and substrates on the maximum hydrogen production rate (HPR) and columbic efficiency (CE) of the MEC system. The obtained results were summarized based on reactor configuration, substrate concentration, electrodes, applied voltage, HPR, and CE. Despite this significant progress, MEC technology still requires substantial developments to be recognized as a commercially viable technology. At the end of this review, the most promising future perspectives were also discussed which could be the appealing solutions for various problems associated with MEC technology. This review supports energy engineers and researchers to analyze the performance of various MECs for future assistance in research.

Innovative electro-biotechnology of plant-microbial fuel cell involves the use of electrodes for the collection of bioelectricity produced by soil rhizosphere microorganisms, utilizing products of photosynthesis and plant residues compounds. The performance of plant-microbial electro-biosystem is highly dependent on the electrode materials and their configurations. Various materials as electrodes for electro-biosystems were analyzed, conducting experiments in laboratory with indoor plants and in situ with forest and garden plants. Graphite wastes of electric transport as cathodes and perforated zinc-galvanized steel plates as anodes were selected as electrodes for plant-microbial fuel cell due to their electro-efficiency, low cost and sustainability in environment. To design multi-electrode system, electrodes were connected each other by copper wires into cathode and anode system. The use of graphite wastes and polyvinyl chloride-insulated copper wires promoted reduction of the cost of electro-biotechnology. Multi-electrode plant-microbial fuel cells with 12 anodes and 11 cathodes with Caltha palustris plants at 10 Ω produced current of 40.98 mA that is 10.1 times more than mono-electrode plant-microbial fuel cells. The parallel connection of two multi-electrode electro-biosystems was resulted in 2.1-fold increase in current compared to the current generated by the one multi-electrode electro-biosystem. The serial connection of three multi-electrode plant-microbial fuel cells was led to an increase in the bioelectric potential in 2.9 times; at the same time, their parallel connection did not increase voltage. Variations of parallel-serial connections of several multi-electrode plant-microbial fuel cells as energy subunits into one complex multi-electro-biosystem were appeared the way to maximize the receiving of plant-microbial bioelectricity.
