(A, B) NAD+/NADH ratio measurements (A) and OH· radical measurements performed using HPF (B) upon exposure to cold stress (5°C, 5 h) and acid stress (pH 4.0, 90 min) and upon preadaptation to cold stress (5°C, 5 h) before exposure to subsequent acid stress (pH 4.0, 90 min). *, significant difference (P < 0.05) compared to the respective no-stress control; •, significant difference compared to no stress followed by acid stress treatment (pH 4.0, 90 min); RFU, relative fluorescence units.
