  Xylitol production by fermentation process is widely studied. However, few works describes the enzymatic production of this polyalcohol. This works aims to determine a model that could explain the xylitol enzymatic production as a function of major variables in this process. For this purpose we applied an adequate statistical analysis and response surface methodology (RSM). Initially, variables were selected using a 25-1 fractioned factorial design. Xylose and NADPH concentrations were chosen for the optimization experiments. In order to use the RSM, experiments according to a 22 factorial design with star points and triplicate in the center were carried out. The statistical analysis resulted in a quadratic model which could explain 98.6 % of the volumetric productivity in xylitol in function of xylose and NADPH concentrations. Using predicted expe..
