FIGURE 3: Effect of potassium (K+) supplementation in yeast growth in YNB-F medium pH 4.0 supplemented or not with 50 mM acetic acid. Growth curves of the parental (●/○), hrk1Δ (■/□), and nha1Δ (▲/▵) strains in the absence (●/■/▲) or presence (○/□/▵) of acetic acid stress in media supplemented with various concentrations of KCl – 1 mM (A), 2 mM (B), 5 mM (C), 20 mM (D), and 50 mM (E). The results are shown as a mean of two independent experiments.
