  2. aYields are shown as mg product per g consumed sugar (average values ± 1 standard deviation, n = 3). Acetate (YSAce), ethanol (YSEtOH), glycerol (YSGly) and biomass (YSBiomass) yields were calculated on total consumed sugars, whereas the xylitol (YSXylitol) yield was calculated on consumed xylose only.
