Bioelectricity from the Yeast Candida boidinii

Abstract

Due to the great changes that the environment is undergoing due to the excessive use of fuels to obtain electrical energy, in the search for new ways to generate this type of energy, this research gives in a new way the use of Candida boidinii yeast as fuel for the generation of electricity through MFC at laboratory scale. Managing to generate maximum values of electric current and voltage of 3.3904 ± 0.0916 mA and 0.70342 ± 0.04726 V, whose values were obtained at a pH of ~6.5848 ± 0.2174 and with a value of 63.701 ± 0.911 mS/cm of electrical conductivity. The cells managed to generate a maximum power density of 7.839 ± 0.159 W/cm2 whose current density was 449.657 mA/cm2. Finally, the cells were connected in series, managing to turn on a green LED, thus demonstrating its effectiveness in the generation of bioelectricity.
