  1. +Specific xylose consumption rate was calculated by dividing the xylose consumed by the time period and average viable dry cell weight concentration as correlated from capacitance readings;
  2. calculated from a0 to 24 h, b2 to 4.5 h, or c8 to 24 h;
  3. average cell viable cell concentration was calculated using the integral method.
