MODIFIED MICROORGANISM HAVING ENHANCED XYLOSE UTILIZATION

摘要

PURPOSE: A modified microorganism with improved xylose utilization is provided to produce chemical materials. CONSTITUTION: A modified microorganism converts xylose into xylitol by xylose reductase, xylitol into xylulose by xylitol dehydrogenase, and xylulose into xylulose-5-phosphate by xylulokinase. The microorganism produces a chemical material using xylose. Xylose is converted into xylitol by xylose reductase. The xylose reductase and xylitol dehydrogenase activities are derived from Pichia stipitis. The xylulokinase activity is derived from Saccharomyces cerevisiae. The modified microorganism is E.coli or Kluyveromyces marxianus. The chemical material includes alcohol, organic acid, amino acid, or vitamin. The modified microorganism is deposited by deposit number KCTC11951BP, KCTC11952BP or KCTC11953BP.
