| Abstract: | For optimizing the fermentation process of compound flocculants-producing bacteria F+, their growth characteristics are investigated and the fermentation kinetics is analyzed. The characteristics of the compound flocculants-producing bacteria F+ are studied,and their influencing factors are investigated. Based on the equations of "Logistic equation" and "Luedeking-Piret equation", the kinetic models reflecting their fermentation features of strain growth, substrate consumption and product generation are constructed respectively. The batch fermentation kinetics model parameter is obtained. The good agreement of predicted values with the experimental results show that the kinetic models are applicable for predicting the actual fermentation process. |
