A Growth curves (n = 3 biological replicates) in YPD medium with 2% glucose. Measurements were taken every 3 h for 36 h. B Residual sugar content (n = 3 biological replicates, **p = 0.001, **p = 0.005, ***p < 0.001) in ethanol fermentation medium containing 20% glucose. Measurements were taken at 72 and 96 h. C Ethanol yield (n = 3 biological replicates, *p = 0.017, **p = 0.001, **p = 0.005, ***p < 0.001). D CO2 weight loss (n = 3 biological replicates, n.sp = 0.088, n.sp = 0.083, *p = 0.011, **p = 0.004, **p = 0.006, ***p < 0.001). E Growth of the Δald4 strain in ethanol liquid medium (n = 3 biological replicates, *p = 0.044, *p = 0.025, *p = 0.024). F Ethanol stress tolerance of strains (the ethanol volume fractions were 4%, 6%, and 8%). G Schematic diagram of ALD4 overexpression or knockout affecting acetaldehyde flow. Error bars represent standard error (SE).
