Biosynthesis of Xylitol from Glucose: Microorganism, Key Enzymes and Genetically Engineered Strains

Xylitol is an important prebiotics, and it is widely used in the fields of medicine and food. In view of the drawbacks of chemical method, much focus has been attracted into the study of xylitol biosynthesis. In this study, microorganism, method and key enzymes in the biosynthesis of xylitol were introduced. In addition, the production of xylitol from glucose by genetically engineered strains was summarized respectively.
