Abstract
Strains ofwere engineered by introducing a chimeric xylose isomerase gene that contains a mutant promoter of theglyceraldehyde-3-phosphate dehydrogenase gene. The promoter directs increased expression of xylose isomerase, and when the strain is in addition engineered for expression of xylulokinase, transaldolase and transketolase, improved utilization of xylose is obtained.
