Abstract
This work is focused on the simulation of the bioproduction of xanthan gum in continuous fermentation systems. We evaluated the cell and gum productivities in a continuous system without cell recycling and in continuous systems with internal and external cell recycling. Results demonstrated that the continuous system can improve the production of gum, since the gum productivity obtained in the systems with external and internal cell recycling were 2.57 and 3.62 g L−1 h−1, respectively, which was about 12–17 times higher than obtained in the reactor without cell recycling.
