FIG 5.

Effect of Hap4p, Hap5, Cin5p, and Put3p on diauxic shift and fermentation capacity. (A) Lag time and growth rate of null mutant strains relative to wild-type strains after glucose-maltose shift. (B) Fermentation rate and maximum CO₂ loss of null mutant strains relative to wild-type strains. (C) Maltose consumption and ethanol production kinetics of CL467.1 and QC18 cin5 null mutant strains. Plotted values correspond to the means of three independent replicates of each strain. * P ≤ 0.05, **, P ≤ 0.01, ***, P ≤ 0.001, ****, P ≤ 0.0001, different levels of significance between mutant and wild-type strains (t test).
