“…Una CCM consta de dos electrodos (ánodo y cátodo) y casi siempre una membrana de intercambio protónico (MIP), el proceso de oxidación tiene lugar en el ánodo produciendo electrones los cuales se conducen por un conductor externo hacia el cátodo donde ocurre la reducción, dando así a las reacciones de oxidación/reducción produciendo la corriente eléctrica [3,4] frutas en estado de descomposición [5,6]. Debido a esto los residuos de frutas y aguas residuales se consideran como fuentes de energía en las CCMs en la actualidad [7]. Los electrodos son esenciales para la oxidación/reducción en esta tecnología, debido a esto diversos grupos de investigación se han dedicado a la búsqueda de materiales para mejorar la generación de voltaje, entre los materiales más usado se encuentra el grafito [8], carbón activado [9], papel de carbón [10], oro [11], nanotubos de carbono [12], etc; los cuales hace que las CCM aumenten el costo de fabricación.…”

Microbial fuel cells (MFC) is a technology that generates electrical energy using organic matter as fuel, becoming a new way of generating electricity that is friendly to the environment. In this research work, MFCs were used with lead and copper electrodes, and as fuel the wastes from Aguaymanto, Camu-camu, Cocona, Granadilla, Tomato and Tuna. The MFCs were monitored for 22 days the voltage, current and pH parameters; as well as current density (CD) and power density (PD) values. The MFC with cocona substrate generated greater voltage during the entire monitoring period, from 0.52 to 0.36 V. While the camu-camu generated a greater current of 6.1 to 5.6 mA, from the first to the last day. All cells show slightly acidic pH, in the same way that volume losses were also observed, being the MFC with granadilla the one that showed greater loss. MFCs with substrates of camucamu, aguaymanto, cocona, tomato, granadilla and prickly pear showed

The paper demonstrates the possibility of using the “Doctor Robik 109” complex microbiological preparation (OOO VIPEKO, Russia), applied in cesspools and sewage caissons, for obtaining electric current in biofuel elements during the utilization of the Ulothrix sp., Spirogyra sp., Elodea canadensis aqueous plant phytomass. The kinetics of electrical parameters of the studied biofuel cells was characterized by a steady and prolonged growth – for at least 30 days. This may be associated with the slow transformation of the used substrate by microorganisms, which additionally ensures the long-term operation of biofuel cells on their basis. In Spirogira sp. biofuel cells, the biological preparation generated the voltage (broken circuit mode) and current strength (short circuit mode) equal up to 746mV and 1745 A, respectively. In Ulothrix sp. biofuel cells, these values comprised 360 mV and 1120 μA for a 25-day period, respectively. When using a E. canadensis substrate, the studied bioagent microorganisms generated the voltage and current of up to 643 mV and 568 μA during a 25-day period, respectively. An increase in the electrical parameters of biofuel cells, which were based on the studied biological preparation and the phytomass of higher aquatic plants and algae, was accompanied by an increase in the number of viable microorganism cells and a decrease in the plant biomass. Since phytomass growth is activated by the phytoremediation measures of additional wastewater treatment or during the eutrophication of water bodies, the proposed method for applying aquatic plants in biofuel cells represents a promising approach to utilizing excess phytomass.
