  1. +Specific xylose consumption rate was calculated by dividing the xylose consumed by the time period and average dry cell weight concentration as correlated from OD measurements; *ethanol productivity was calculated by dividing the ethanol concentration by time of fermentation;
  2. calculated from a24 to 48 h, b0 to 48 h, c0 to 120 h, or d0 to 24 h;
  3. average RaBIT fermentation calculations were performed by averaging the data from the two cycles.
