Abstract
Fermentation is typically modelled by kinetic equations giving the time evolutions for biomass, substrate, and product concentrations. In the present study, production of bioethanol from glucose, substrate and Saccharomyces cerevisiae (S. cerevisiae) as a biomass was investigated through a batch fermentation process. Time variation of the S. cerevisiae growth, glucose utilization and ethanol productivity was described using different kinetic models and analytically solution. The kinetic constants were determined through the fitting of experimental data with the kinetic model equations. The results demonstrated that the Monod, Logistic, and Luedeking-Piret served as the best describing models for S. cerevisiae growth, glucose, and ethanol concentrations, respectively. Moreover, determination of substrate concentration in according to time via analytical solution of equation was hallmark result of this research.
