“…The experiment altered the time duration of the reaction, as Ni treated for 30 days obtained 150-200 mW/m 2 energy and Cd and Hg treated for 7 and 15 days achieved a removal rate of 60% and 55% along with energy output of 700-750 mW/m 2 and 800 mW/m 2 , respectively. In 2019, Zhang et al [58] analysed the Cr (VI), which is mostly focused upon heavy metal due to its toxicity and high mobility. A new reactor combination of MFC was developed using Platanus acerifolia leaves and applied for remediation of chromium ions.…”

A wide variety of pollutants are discharged into water bodies like lakes, rivers, canal, etc. due to the growing world population, industrial development, depletion of water resources, improper disposal of agricultural and native wastes. Water pollution is becoming a severe problem for the whole world from small villages to big cities. The toxic metals and organic dyes pollutants are considered as significant contaminants that cause severe hazards to human beings and aquatic life. The microbial fuel cell (MFC) is the most promising, eco-friendly, and emerging technique. In this technique, microorganisms play an important role in bioremediation of water pollutants simultaneously generating an electric current. In this review, a new approach based on microbial fuel cells for bioremediation of organic dyes and toxic metals has been summarized. This technique offers an alternative with great potential in the field of wastewater treatment. Finally, their applications are discussed to explore the research gaps for future research direction. From a literature survey of more than 170 recent papers, it is evident that MFCs have demonstrated outstanding removal capabilities for various pollutants.

“…In 2019, Zhang et al [21] developed a reactor combining adsorption and microbial fuel cells using Platanus acerifolia for removing Cr(VI) from groundwater and soils, where the initial Cr(VI) concentration was 50 mg/L and the adsorption efficiency achieved 98% after 16 h. The overall Cr(VI) removal efficiency was significantly improved through leaching and 40% of the Cr(VI) in the soil column was removed.…”

Microbial fuel cells (MFC) are an emerging technology for waste, wastewater and polluted soil treatment. In this manuscript, pollutants that can be treated using MFC systems producing energy are presented. Furthermore, the applicability of MFC in environmental monitoring is described. Common microbial species used, release of genome sequences, and gene regulation mechanisms, are discussed. However, although scaling-up is the key to improving MFC systems, it is still a difficult challenge. Mathematical models for MFCs are used for their design, control and optimization. Such models representing the system are presented here. In such comprehensive models, microbial growth kinetic approaches are essential to designing and predicting a biosystem. The empirical and unstructured Monod and Monod-type models, which are traditionally used, are also described here. Understanding and modelling of the gene regulatory network could be a solution for enhancing knowledge and designing more efficient MFC processes, useful for scaling it up. An advanced bio-based modelling concept connecting gene regulation modelling of specific metabolic pathways to microbial growth kinetic models is presented here; it enables a more accurate prediction and estimation of substrate biodegradation, microbial growth kinetics, and necessary gene and enzyme expression. The gene and enzyme expression prediction can also be used in synthetic and systems biology for process optimization. Moreover, various MFC applications as a bioreactor and bioremediator, and in soil pollutant removal and monitoring, are explored.

“…Results of XPS analysis also revealed that chemisorption reaction between mercury and the surface of H 2 O 2 -modified biochar took place in pseudo-second order kinetics, while physical sorption of mercury occurred on raw biochar. Zhang, Hu, et al (2019) remediated Cr(VI)-contaminated soils using combined adsorption and microbial fuel cell process and reported 98% Cr(VI) removal in 16 h. Li, Chen, Liao, Chen, Liao, and Pan (2019) prepared a polymer-functionalized nanocomposite (HFO-PsAX) for selective adsorption of Mo(VI) from water. The optimum adsorption of molybdate was at pH ≈ 4 and temperature showed insignificant effect on the adsorption capacities.…”
