Glucose concentration (A), xylose concentration (B) and ethanol concentration (C). Filled symbols represent experiment without prefermentation and unfilled symbols represent duplicate experiments with prefermentation. The time of enzyme addition, in the case of prefermentation, is marked with an arrow.Back to article page
