FIGURE 2: Estimation of plasma membrane potential of S. cerevisiae BY4741 and BY4741 hrk1Δ under acetic acid-stressed and non-stressed cultivations. Plasma membrane potential (Arbitrary fluorescence units) of BY4741 (●/○) and BY4741 hrk1Δ (■/□) cultivated in YNB medium pH 4.0 in the presence (○/□) or absence (●/■) of acetic acid stress (50 mM acetic acid at pH 4.0). The data presented represents average values ± SD of at least two independent experiments.
