Recently, there has been great interest in microbial fuel cells and the different substrates used within them for the generation of electrical energy. Due to this, the yeast Wickerhamomyces anomalus has been used as a new source of electricity generation, this substrate was molecularly identified with a percentage of 99.82% identity. With which it was possible to generate a maximum current and voltage on the ninth and eighth day of 2.6678 ± 0.0981 mA and 0.823 ± 0.125 V, all this an electrical conductivity of the substrate of 49.37 ± 1.12 mS/cm on the ninth day and a pH of operation of 6.32 ± 0.421 in those days. In the same sense, a maximum power density of 8.176 ± 0.855 W/cm2 was shown for a current density of 362.057 mA/cm2. These values demonstrate the great potential that this yeast has for the generation of electric current and its new use as fuel in microbial fuel cells; being an eco-friendly alternative for the environment.
