Fig. 7From: Directed evolution and secretory expression of xylose isomerase for improved utilisation of xylose in Saccharomyces cerevisiaeCo-fermentation profiles of xylose-assimilating strains expressing different XIs and an empty vector. YPDX medium containing 6% glucose and 8% xylose was used as fermentation medium. Mean values and standard deviations of triplicates are shown. Symbols: Glucose (●), Xylose (△), Ethanol (■), and Xylitol (◇)Back to article page
