Sensitivity to H2O2. WT and flX1Δ cells were cultured at 30°C in YEP liquid medium supplemented with either glucose or glycerol (2% each) as carbon source. Where indicated, H2O2 at the indicated concentration was added. Cell growth was estimated at the exponential (5 h) and stationary phase (24 h) by measuring the absorbance at 600 nm ( ). In the histogram, the of the cell cultures grown in the presence of H2O2 is reported as a percentage of the control (i.e., the of cell cultures grown in the absence of H2O2, set arbitrary equal to 100%). The values reported in the histogram are the means (±SD) of three experiments.
