Wide distribution of colony formation time for the oxidative-stress-prone cells. The wild-type strain and ΔsodAΔsodB strain were starved for 8 h and plated on LB agar plates. Subsequently, we recorded the time at which visible colonies were newly formed (~500 colonies were examined for each strain). Compared to the wild-type strain, the ΔsodAΔsodB strain exhibited a much wider distribution, with its tail stretching to ~50 h. We observed similar distributions in two biological replicates
