Effects of CTT1 and PRX1 overexpression on xylose-fermenting ability of the recombinant strain YRH396. a Cell growth ability of the yeast strains with CTT1 or PRX1 overexpression, and the transformants with the empty vector pRS41H served as a control. YPD agar medium supplemented with 5 mM H2O2 was applied to test the oxidative stress tolerance ability of the different strains, and YPD agar medium was used as a control. b Growth ability of the CTT1 or PRX1 overexpression strains compared to the control strain with the control empty vector. Ethanol fermentation was performed with 4 g/L yeast extract, 3 g/L peptone, and 40 g/L xylose. c Xylose consumption of the yeast strains after fermentation for 96 h. The results shown were the mean values of triplicate experiments
