Effects of furfural on growth and ethanol fermentation on Xyl in K. marxianus BUNL-21 and DMKU3-1042 and S. stipitis. K. marxianus BUNL-21 (a, d) and DMKU3-1042 (b, e) and S. stipitis (c) were grown in YPXyl medium supplemented with 10 mM furfural at 30 °C (a–c) or 37 °C (d, e) under a shaking condition at 160 rpm, and samples were taken every 12 h until 72 h of incubation. The dry cell weight (filled diamonds) and concentrations of Xyl (filled triangles), ethanol (filled squares), xylitol (open triangles) and acetic acid (crosses) are indicated. Bars represent the ±SD of values from experiments performed in triplicate
