Microbial and Enzymatic Process for Xylitol Production from D-glucose

A microbial and enzymatic process for xylitol production that initiates from D-glucose occurs by virtue of a three-step process in which D-arabitol is the first intermediate product and D-xylulose is the second. To date, the steps of the formation of D-arabitol and the conversion of xylitol from D-xylulose are key points of departure for promoting the overall process for xylitol production from D-glucose. This review provides comprehensive insights regarding potential methods of xylitol production from D-glucose, which might be an alternative to the classical process that utilizes D-xylose as substrate.
