Fig. 4From: Directed evolution and secretory expression of xylose isomerase for improved utilisation of xylose in Saccharomyces cerevisiaeFermentation of two strains expressing intracellular XI and extracellular XI. YPDX medium containing 2% glucose and 2% xylose was used for fermentation. Mean values and standard deviations of triplicates are shown. *p < 0.03.
