^aParameters were calculated from the mid-exponential growth phase on glucose and from the steady-state phase of xylose utilization. Estimated standard errors were <15%. ND, not detected.

^bValues represent averages from 4 individual fermentations performed either with Sixfors (2×) or Labfors (2×) bioreactor systems.

^cThe ethanol yield and the carbon balance were calculated based on data acquired by the Labfors bioreactor system.
