In this study, two simple empirical kinetic models were used to
describe yeast cell growth and bioethanol production during batch
fermentation of raw juice. The results from the models’ simulations
showed good agreement with the experimental data obtained at
different fermentation times. The yeast cell growth could be ex-pressed by a logistic equation. The production of bioethanol fol-lowed the modified Gompertz model. Both models can explain the
fermentation characteristics of yeast cells and their ability to pro-duce bioethanol.
Further research should be directed towards applying these
models to predict and compare results of full industrial scale bio-ethanol production from raw juice
