  1. aBiomass, glycerol and ethanol yields were calculated by plotting the consumed sugar/s (g l-1) against the produced biomass (g biomass l-1), the produced glycerol (g glycerol l-1) or the produced ethanol (g ethanol l-1) respectively on the phase of constant and highest values. bXylitol yields were calculated by plotting the consumed xylose (g xylose l-1) against the produced xylitol (g xylitol l-1) on the phase of constant and highest values.
