| Abstract: | The batch kinetics of high concentrated ethanol fermentation by a strain of Saccharomyces cerevisae was studied in this paper. The unstructed kinetics model was established to describe the process of high substrate and high product concentration fermentation. The Genetic Algorithm was used to seek best parameters value for good data simulation, the model described the fermentation process well. Then the model was used to predict the batch ethanol fermentation at 24. 7% initial glucose concentration with good predicting performace. As a result,the unstructed kinetics model could be used to describe and predict high substrate and high product concentration batch ethanol fermentation process. |
| Keywords: | high ethanol concentration fermentation kinetics model Saccharomyces cerevisiae evalua-tion of the kinetics parameters |
