Activities of SOD (A) and catalase (B) in S. cerevisiae W303-1A and its derivatives ΔPDR12 and ΔWAR1 under AA treatment. Data are mean ± SEM (n = 4–6). Significantly different from respective values for: *control (pH 3.0) with P < 0.05, aW303-1A wild strain with P < 0.01, and bcontrol (pH 6.75) with P < 0.05.
