Improved fermentation by the strain YC1 compared to the control strain S-C1 in SC medium containing glucose (20 g/L) + acetic acid (2 g/L) (a, d), furfural (1.5 g/L) (b, e), or acetic acid (2 g/L) + furfural (1.5 g/L) (c, f). Results were the means of duplicate experiments; error bars indicating standard deviations were not visible when smaller than the symbol size
