“…Although there are different commercial systems available, The LTC 3108 is the DC/DC converter most utilised in recent papers [139][140][141] for the energy management systems powered by MFC. One of the reasons is the very low voltage start-up needed for the converter.…”

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.

“…Up to now, several MFCs were connected in series or in parallel to overcome the low voltage. Nevertheless, although a serially stacked MFCs unit could provide a higher voltage, it is ineffective due to voltage reversal, leading to a signi cant overall voltage decay (Kim et al 2019). Moreover, much effort have been deployed to control the voltage reversal occurrence by connecting individual MFC units with a power point tracking system to charge a stacked polarized capacitor (Papaharalabos et al 2017).…”

A microbial fuel cell (MFC) has been conceived and constructed for the treatment of the sheep manure wastes and conversion them into clean sustainable renewable energy. The chemical oxygen demand (COD) removal of 10 days running MFC increased by 58.7% showing simultaneously an increase in the cell voltage. However, this MFC technology faces practical barriers since it produces low electric energy. A power management system including the MFC, operational amplifier, solar photovoltaic panel and a boost DC/DC converter, was elaborated in this respect. The low voltage output obtained from the MFC, was thus substantially increased by the amplifier prior to polarization by a photovoltaic module with solar radiation. The amplified voltage was thus sufficiently enough and in consequence, utilized to feed a light emitting diode. The low output voltage 0.5 V was simply harvested, successfully boosted up to approximately 2 V (i.e. 4 times higher) and effectively harnessed as a power supply. This novel application is very interesting to utilize the natural bioenergy contained in wastes to supply small electronic devices.

“…The main obstacle to overcome is the MFC voltage reversal phenomenon observed when electrically connecting units in series [30] , [31] . To avoid this, all successful studies so far have connected units in parallel, or connected stacks in series/parallel combinations [32] , [33] , and always employed power management systems with energy buffers such as capacitors [23] , [34] , [35] or batteries [20] , [36] . Therefore, the challenge for a battery-free MFC system is to reach sufficiently high voltages, through electrical series connections without any voltage reversal.…”

Highlights Urine fed microbial fuel cell stacks were used as a direct power source. Maintaining individual cells at high potential enables stable series connections. A stack continuously and directly powered LED spotlights in the field. A stack was connected to the lights through a LED-driver to limit cell reversal. Directly connecting LEDs to a stack is more stable than using LED drivers.
