Abstract
La levadura Saccharomyces Cerevisiae fue utilizada como biocatalizador dentro del ánodo microaerofílico de dos celdas de combustible microbianas. Se hallo que usando ferricianuro de potasio como aceptor final de electrones en el cátodo, las levaduras producen un voltaje de ≈ 100 mV mayor a las celdas de combustible sin levaduras luego de 1.5 días de funcionamiento, con un voltaje a circuito abierto de ≈ 150 mV. La cinética del microorganismo fue medida fuera de las celdas de combustible y comparada con el desarrollo de voltaje a través del tiempo, indicando que el crecimiento de las levaduras ayuda al incremento de voltaje.
The yeast Saccharomyces Cerevisiae was used as a biocatalyst within a microaerophilic two-compartment microbial fuel cell anode. It was found that by using potassium ferricyanide as an electron acceptor the yeasts produce 100 mV voltage more than cells without yeast after 1.5 days of operation with a 150 mV voltage open circuit. The kinetics of the microorganism was measured outside the fuel cells and compared to the development of voltage over time, indicating that the growth of the yeasts helps increase the voltage.
