Microbial xylitol production from renewable resources is expected to have potentials to realize a cheaper production of xylitol with low environmental impact. In this study, in order to realize enhanced production of xylitol using Candida magnoliae from corn cobs, we developed a simplified metabolic reaction model concerning xylose metabolism. The metabolic flux analysis was successfully applied for effective production of xylitol and it can be a useful tool to obtain reliable information not only for genetic modification but also for operational improvements in microbial processes.
