| Abstract: | A model of ethanol fermentation by Zymomonas mobilis ATCC 10988 on the medium containing glucose and fructose is proposed. This model was developed on the basis of metabolic analysis and many experimental findings. When glucose was used as the substrate, the dependence of the carbon fraction (α) assimilating to biomass on the specific growth rate (μ) could be well correlated to α = 0.25μ + 0.012. This correlation resulted in a novel equation for specific glucose uptake rate, which could describe the Z. mobilis fermentation in both batch and continuous modes. When fructose and glucose were both presented in the liquid medium, the model could predict the uptake of glucose and fructose as well as the formation of biomass, ethanol and sorbitol by Z. mobilis. All parameters used in the model were independently evaluated on the basis of various experimental findings. Good agreement was found between the model predictions and data of Z. mobilis fermentation on media containing both glucose and fructose. The proposed model could also describe the behavior of ethanol fermentation on sucrose medium supplemented with immobilized invertase. |
