  1. aConsumed xylose under the assumption that no additional xylose was released by enzymatic hydrolysis
  2. bConsumed glucose calculated based on the produced ethanol using the theoretical ethanol on glucose yield of 0.51 g g−1
  3. cMetabolic yields based on the xylose and glucose consumption calculated as described in a and b
