^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.
