  1. Fermentations were carried out at 30 °C, unless mentioned otherwise
  2. A = Theoretical ethanol yield (%) reached when fermentation stopped
  3. B = Vmax, maximum rate of fermentation (g L−1 h)
  4. C = Time to reach Vmax (h)
  5. D = C50, time to consume 50% of the initial sugar content (h)
  6. ng no growth
