Bioelectricity Generated by Microbial Fuel Cells from Spearmint (Mentha Spicata) and Ribbon Plant (Chlorophytum Comosum)

Abstract

Clean energy such as bioelectricity, a sustainable energy, obtains electricity associated with biological processes that do not generate greenhouse gases. The research aimed to produce bioelectricity using microbial fuel cells (MFCs) that transform chemical energy stored in organic matter into electricity. Peppermint (Mentha spicata) and ribbon plant (Chlorophytum comosum) MFC were designed in the district of Yanacancha, Chupaca-Junín. For the experimental process, microbial fuel cells were built, 3 batteries for mint and 3 batteries for ribbon plant, using graphite rods as electrodes. The initial characterization of the soil used in the pile was carried out, and then the global solar radiation was measured during the operation of the pile. In the investigation, a greater bioelectricity was achieved when the pH and temperature of the soil of the microbial fuel cell were 7.04 and 10.80 °C in peppermint MFC and 6.43 and 12.83 °C in tape MFC where bioelectricity of 245.37 mV was generated, 601.15x10-6 W in peppermint MFC and 505.45 mV, 2552.52x10-6 W in ribbon MFC respectively, so the ribbon microbial fuel cell (MFC) was the most efficient for bioelectricity generation.
