Table 1 Comparison of fermentation performance of Sn cerevisiae strains MA-R4 and MA-B4 in anaerobic batch fermentations with YPD and YPX media
Strain | Medium | Max. specific glucose consumption rate (g-glucose/g-DCW/h) | Max. specific xylose consumption rate (g-xylose/g-DCW/h) | Max. specific ethanol production rate (g-ethanol/g-DCW/h) | Biomass yield (g-DCW/g-consumed total sugar) | Ethanol yield (g-ethanol/g-consumed total sugar) | Xylitol yield (g-xylitol/g-consumed xylose) | Glycerol yield (g-glycerol/g-consumed total sugar) | Acetic acid yield (g-acetic acid/g-consumed total sugar) |
