Fermentation results: concentrations of a ethanol and residual glucose, b glycerol, and c intracellular content of pyruvate during batch ethanol fermentation. Data were collected from batch fermentation experiments conducted in sealed 100-mL serum bottles at 45 °C with three biological replicates. Control: the strain overexpressing wild-type SPT15. Values are means and standard deviations (n = 3)
