Fermentation performance of S. cerevisiae YB-2625 (YB) and S. cerevisiae S288C (Sc) in the presence of mixed sugar. Batch fermentation was performed in 100 mL medium containing 4 g/L yeast extract, 3 g/L peptone, 80 g/L glucose, and 20 g/L xylose in 250 mL Erlenmeyer flasks with initial OD₆₀₀ ~ 0.2 at 150 rpm and 30 °C under micro-aerobic condition. a and b glucose and xylose consumption; c and d glycerol and acetic acid generation. The green and red colors stand for S. cerevisiae S288C and S. cerevisiae YB-2625, respectively. The arrows indicate the time points for comparative transcriptomic analysis (i.e. 7 and 48 h). The results shown were the mean values of triplicate experiments
