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 (A _600 nm). In the histogram, the A _600 nm of the cell cultures grown in the presence of H₂O₂ is reported as a percentage of the control (i.e., the A _600 nm 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.
