| Abstract: | Chitosan alginate (ACA) microcapsules were applied in xylitol batch fermentation. The microcapsules were used repeatedly in four batches. Comparing with free cells fermentation and Ca alginate immobilizing fermentation, the fermentation by microcapsules had better and fixed conversion rate (65%), while the end time of microcapsule fermentation was enhanced and fixed to 50 hours. |

| Keywords: | microcapsule immobilization fermentation conversion rate |
