“…Por otro lado, los valores de la conductividad eléctrica del sustrato utilizado son mostrados en la Figura 3 (b), lográndose observar que los valores aumentan desde el día primer día (57.792 ± 1.732 mS/cm) hasta el día 16 (152.326 ± 4.58 mS/cm) para después disminuir hasta el último día (58.556 ± 7.485 mS/cm). Los valores de la conductividad eléctrica, dependen de la resistencia de las celdas; el aumento de estos valores nos indica una disminución de a la resistencia interna del sustrato para el paso de flujo de electrones, observándose en los últimos días una disminución que depende de la sedimentación observada en los últimos días de operación de las celdas de combustible microbiana [30,31].…”

Due to the increase in the production of fruits for consumption and export, large amounts of waste from the same fruits are being generated, causing a great environmental problem, especially in developing countries that do not have an adequate process for their use or treatment. In this context, microbial fuel cells are presented as a novel technology that could provide a solution to this problem in the future by reusing organic waste as an energy source. In the present work, microbial fuel cells (MFC) were manufactured on a laboratory scale using apple waste as a substrate with Zinc and Copper electrodes. It was possible to generate electrical current and voltage peaks of7.567 ± .0117 mA and 1.452 ± 0.023 V, which operated with an electrical conductivity of the substrate of 152.326 ± 4.58 mS/cm and with an acid pH on day 16, where it was observed their maximum values. An internal resistance of approximately 31.548 ± 4.871 Ω was found, whose power density was 466.27 ± 16.824 mW/cm 2 at a current density of 4.424 A/cm 2 . The microbial fuel cells were connected in series managing to generate a voltage of 3.17 V, enough to light a red LED light.

“…Some studies indicate that some enterobacteria, such as P. vulgaris, may be associated with the generation of electricity in MFC with organic waste substrates [58]. On the other hand, it is known that in most studies on microbial communities of MFC anodes, bacteria belonging to the Proteobacteria phylum are frequently isolated [59,60]. In other investigations, P. vulgaris has been used in MFCs to generate bioelectricity due to its metabolic reducing power, which through electron mediators can improve the energy efficiency of the MFC [54,61,62].…”

This research used tomato waste as a substrate (fuel) in Single Chamber-Microbial Fuel Cells (scMFC) on a small scale. The electrochemical properties were monitored, the functional groups of the substrate were analyzed by Fourier Transform Infrared Spectrophotometry (FTIR) and a microbiological analysis was performed on the electrodes in order to identify the microorganisms responsible for the electrochemical process. The results show voltage peaks and an electrical current of 3.647 ± 0.157 mA and 0.957 ± 0.246 V. A pH of 5.32 ± 0.26 was measured in the substrate with an electrical current conductivity of 148,701 ± 5849 mS/cm and an internal resistance (Rint) of 77. 517 ± 8.541 Ω. The maximum power density (PD) displayed was 264.72 ± 3.54 mW/cm2 at a current density (CD) of 4.388 A/cm2. On the other hand, the FTIR spectrum showed a more intense decrease in its peaks, with the compound belonging to the phenolic groups being the most affected at 3361 cm−1. The micrographs show the formation of a porous biofilm where molecular identification allowed the identification of two bacteria (Proteus vulgaris and Proteus vulgaris) and a yeast (Yarrowia lipolytica) with 100% identity. The data found show the potential of this waste as a source of fuel for the generation of an electric current in a sustainable and environmentally friendly way, generating in the near future a mechanism for the reuse of waste in a beneficial way for farmers, communities and agro-industrial companies.

“…In the following days, the values experienced a gradual decrease until they produced 1.93 mA on day 30. The peak current values shown in the first days are attributed to the good formation of the electrogenic biofilm [46], which depends largely on the measurement of the carbon sources present in the substrates [47], which act as an energy supply in the biological process of microorganisms to produce electric current [48]. As the organic compounds decrease, the production of electrons is reduced, thus generating a lower electrical current in the last few days [49].…”

The growing global energy demand drives the need to develop new clean energy technologies. In this context, microbial fuel cells (MFC) are one of the emerging technologies with great potential for eco-friendly energy generation; however, the correct choice of electrode material is a significant limitation in the optimal configuration of MFCs. Therefore, this research evaluated the efficiency of activated carbon (AC) anode electrodes for bioenergy production in MFC using synthetic wastewater as a substrate. Peak values of voltage (1120 ± 0.050 mV), current (4.64 ± 0.040 mA), power density (208.14 ± 17.15 mW/cm2), and current density (5.03 A/cm2) were generated, and the Rint obtained was 214.52 ± 5.22 Ω. The substrate was operated at pH values from 5.31 to 7.66, maximum ORP values (858 mV) were reached, and turbidity was reduced to 25.11 NTU. The SEM-EDS (scanning electron microscopy–energy-dispersive X-ray spectroscopy) analyses allowed us to observe the morphology and composition of the AC electrodes, revealing a predominance of O, C, Si, Al, Fe, K, and Ca. It is concluded that the AC electrodes have the potential to produce bioenergy at a laboratory by means of MFC.
