- The experiments were performed using the xylose-fermenting S. cerevisiae strain KE6-12 (Mean values are given for the reference SSF experiment using baker’s yeast: the standard deviation was less than 2%), glu: glucose, xyl: xylose, EtOH: ethanol.
- a Based on total amount of glucose added to SSF/SSCF.
- b Based on consumed xylose.
- c Based on total amount of xylose added to SSF/SSCF.
- d Calculated for the first 8 hours.
- e Based on total amount of glucose and xylose added to SSF/SSCF.
