Growth, xylose consumption, and product formation in the developed S. cerevisiae strains. [a]: Aerobic growth of strains BTY29, BTY30, BTY33, and BTY34. Fermentations were performed in erlenmeyer flasks at 30 °C and 200 rpm, YNB media without uracil containing xylose 2% as sole carbon source was used. [■]: OD600; [♦]: xylose; [×]: ethanol; [*]: xylitol; [●]: glycerol; [Δ]: acetic acid. [b]: Semi-anaerobic growth of BTY29, BTY30, BTY33, and BTY34. Fermentations were performed in SCHOTT flasks at 30 °C and 100 rpm in YNB without uracil media containing a mixture of glucose 0.5% and xylose 2% as carbon source. [■]: OD600; [+]: glucose; [♦]: xylose; [×]: ethanol; [*]: xylitol; [•]: glycerol; [Δ]: acetic acid
