Abstract
Disclosed herein are Xylitol dehydrogenase-inactivated and arabinose reductase-inhibited mutant of, a method of producing a high yield of xylitol using the same, and xylitol produced by the method. More specifically, disclosed are a method for producing a high yield of xylitol, in which a high concentration of xylose contained in a biomass hydrolyzate is converted to xylitol using xylitol dehydrogenase-inactivated mutant of, without controlling dissolved oxygen to a low level, as well as xylitol produced according to the method. Also disclosed are a xylitol production method, in which the production of byproduct arabitol, which is produced when using a biomass as a substrate and adversely affects the yield of xylitol, is significantly reduced through the use ofmutant ara-89 (KCTC 11136bp) having an inhibited activity of arabinose reductase converting arabinose to arabitol, thus increasing xylitol productivity, as well as xylitol produced by the method.
