Fig. 4From: Systematic optimization of gene expression of pentose phosphate pathway enhances ethanol production from a glucose/xylose mixed medium in a recombinant Saccharomyces cerevisiaeSuccessive changes in d-xylose consumption by introduction of each PPP gene. Black line: increased by less than 1.2-fold, Blue and dashed line decreasing, Red thick line: increased by more than 1.2-fold. Colored panels: gene combination with highest consumption rate in single (Yellow), double (Orange) and triple (Red) of PPP gene(s), respectivelyBack to article page
