Zymomonas mobilis CP4 fed-batch fermentations of glucose-fructose mixtures were carried out at different operational conditions (aeration, feed rate and substrate concentration) to test their effects on the system productivity. In these fermentations, the main products were ethanol and sorbitol. Kinetic parameters were calculated using the experimental data. However, parameters in the sorbitol synthesis rate were estimated from data recorded in different experiments in order to avoid the effect of the simultaneous cell growth and ethanol synthesis. In this case, the crude cell extract was used as source of the enzyme responsible for the sorbitol synthesis. The highest degree of conversion of fructose into sorbitol obtained with the extract was equal to 71% in a sugar mixture with an initial concentration of 200 g/l. Results obtained in the fed-batch fermentations showed that aeration of the culture has a positive effect on the final biomass concentration. However, final ethanol concentration is lower under aerated conditions. The best sugar yields to biomass and ethanol were 0.032 and 0.411 g/g, respectively. On the other hand, the highest sorbitol yield in the fed-batch fermentations was 0.148 g/g.
