Title: Recombinant Zymomonas mobilis with improved xylose utilization

Abstract

A strain derived from Zymomonas mobilis ATCC31821 or its derivative capable of producing ethanol upon fermentation of a carbohydrate medium containing xylose to provide enhanced xylose utilization and enhanced ethanol process yield, the strain or its derivative comprising exogenous genes encoding xylose isornerase, xylulokinase, transaldolase and transketolase, the genes are fused to at least one promotor recognized by Zymomonas which regulates the expression of at least one of the genes.
