Figure 5.

Respiratory-deficient mutant cells of S. cerevisiae W303-1A are more resistant to acetic acid and acid-induced death is not inhibited by cycloheximide. Relative survival (percentage of cfu on YEPD agar plates; 100% corresponds to the number of cfu at time 0) of wild-type, ρ⁰ (lacking mitochondrial DNA), ΔATP10 (depleted of ATPase), and ΔCYC3 (depleted of CytC) cells of S. cerevisiae incubated for 200 min with acetic acid in the absence (black bars) or presence (white bars) of cycloheximide.
