Kinetic study and modeling of xylitol production using Candida tropicalis in different culture media using unstructured models

Unstructured models for cell growth, xylose consumption and xylitol production were applied to describe the fermentation kinetics of using Candida tropicalis in synthetic medium,and non-detoxified oil palm empty fruit bunch (OPEFB) hydrolysate at 100 mL flask scale. In medium, experimental maximum specific growth rate (μmax) mass yield factor(YX/S) closer results Tessier model than those Contois Monod models. Whereas, OPEFB hydrolyzate, these parameters According models’ results, is mainly produced during phase. The medium had a coefficient variation 32 33%, respectively. significance this study lies simplifying process through an unstructured non-segregated three events same time, substrate metabolite production.
