Impact of the ADE genes overexpression on ethanol fermentation. Ethanol fermentation was performed in bioreactor with 5 g/L acetic acid (a) or mixed inhibitors (c) supplemented, and pH was controlled at 4.5, and in flask without external inhibitors addition (b) and with corn stover hydrolysate (d). Results are the average of three independent experiments
