Abstract

This study simultaneously evaluated fermentation kinetics and H+ fluxes during fermentation by Saccharomyces cerevisiae in order to elucidate the biochemical mechanisms behind bioethanol production induced by ELF magnetic fields. Fermentation kinetics were monitored by glucose uptake, ethanol production, secondary products (glycerol), pH, biomass, and biochemical characterization of ATPase activity through proton efflux density measurements.
