  1. The maximum specific growth rate (μmax) is represented in h-1. The specific consumption rate of glucose (r glu), xylose (r xyl) and specific ethanol productivity (r E) are represented in g g cell dry weight-1 h-1. The yield of biomass (Y X/S), ethanol (Y E/S), glycerol (Y gly/S), and acetate (Y Ac/S) are represented in g g consumed sugars-1. All values are calculated during the exponential phase identified by natural logarithm of biomass and culture time. The values are average from duplicate experiments and ± indicates deviation from the mean.
