Cell growth, sugar consumption, and ethanol production of mutant strains selected at different time points during ALE in RMX5. 8b-S1, 8b-S8, 8b-S11, 8b-S19, and 8b-S38 were selected after the 1st, 8th, 11th, 15th, 19th, and 38th transfers, respectively. Strains were cultured in 40 mL RMX5 in 50-mL shake flasks at 100 rpm and 30 °C. Spectinomycin at a final concentration of 50 μg/mL was added for recombinant strains. Three replicates were performed for each experiment
