“…Michael Potter [27] initially researched the formation of bioelectricity by many microbes, which transform energy stored in the chemical bonds of the substrate into electrical energy via the breakdown of diverse substrates, mainly organic molecules from wastewater. BEC has gained popularity due to its eco-friendly and energysaving properties [28,29]. Researchers have concentrated on improving electrode materials, designing BEC, and screening and isolation of electrochemically active bacteria (EAB) or inert model microbes to increase the applicability of BEC [29].…”

“…Currently, the generation of electricity is being studied through biolectrochemical systems, also called biolectrochemical fuel cells, which can be enzymatic fuel cells (EFCs) and microbial fuel cells (MFCs) (Ivars-Barceló et al, 2018). This technology is an emerging area for the alternative generation of renewable energy, which has a valuable potential in environmental bioremediation such as wastewater treatment (Ray and Ghangrekar, 2015;Hu et al, 2018;Javed et al, 2018). The design of the cell used in these systems has been the focus of attention by the scientific community in order to increase the production of energy (Mora and Bravo, 2017).…”

This research proposes an alternative for companies and farmers through the production of electricity using microbial fuel cells (MFCs) using waste from export products. Nine MFCs were manufactured with zinc and copper electrodes; and as substrates, pineapple, potato and tomato pulp wastes were used in the anode chamber, and residual sludge in the cathode chamber. It was observed that the MFCs with pineapple substrate generated higher values of the electrical parameters, resulting in voltage and current values of 0.3484 ± 0.003 V and 27.88 ± 0.23 mA, respectively. It was also observed that the maximum power density was 0.967 ± 0.059 W/cm2 at a current density of 0.04777 A/cm2 for the same substrate. Acid pH values were observed in the three samples, while the conductivity reached its maximum value on day 23 (69.47 ± 0.91 mS/cm) which declined until the last day of monitoring; the turbidity values increased abruptly after day 22 until the last day where a value of 200.3 ± 2.52 UNT was observed for the pineapple substrate. The scanning electron microscopy for the pineapple substrate MFC electrodes shows the formation of a porous biofilm on the zinc and copper electrodes. These results show that a new form of electricity production has been achieved by generating high voltage and current values, using low-cost materials.

“…These molecules were then converted or used directly as a sustainable alternative to fossil fuels (Yuan et al, 2019). With the growing desire for environment-friendly and energy-saving processes (Zhang and Angelidaki, 2015), bioelectrochemical systems attracted much attention for their green and sustainable characteristics (Ghosh and Ghangrekar, 2015).…”

Bioelectrochemical systems are revolutionary new bioengineering technologies which integrate microorganisms or enzymes with the electrochemical method to improve the reducing or oxidizing metabolism. Generally, the bioelectrochemical systems show the processes referring to electrical power generation or achieving the reducing reaction with a certain potential poised by means of electron transfer between the electron acceptor and electron donor. Researchers have focused on the selection and optimization of the electrode materials, design of electrochemical device, and screening of electrochemically active or inactive model microorganisms. Notably, all these means and studies are related to electron transfer: efflux and consumption. Thus, here we introduce the basic concepts of bioelectrochemical systems, and elaborate on the extracellular and intracellular electron transfer, and the hypothetical electron transfer mechanism. Also, intracellular energy generation and coenzyme metabolism along with electron transfer are analyzed. Finally, the applications of bioelectrochemical systems and the prospect of microbial electrochemical technologies are discussed.
