Figure 2

Effects of acetic acid on the fermentation of glucose-xylose mixture (A-C) and xylose (D-F) at 30°C by S. cerevisiae MN8140X. Acetic acid was added to the fermentation at a concentration of 0 mM (A, D), 30 mM (B, E) and 60 mM (C, F). Symbols: closed circles, biomass [optical density at 600 nm (OD 600)]; open triagnles, glucose; closed squares, xylose; open circles, ethanol; closed triangles, glycerol; open squares, xylitol. The values are the averages of four independent experiments, ± SEM.
