FIG 4.

SC exhibits competitive advantage against its ancestor within a specific time window in prolonged stationary phase. Competition dynamics between ZK819 (ancestor) and SC in differently aged LB. Left panel shows competition experiments where ZK819 is inoculated in 1,000-times-higher frequency than SC. Right panel shows competing strains grown individually in the same-age medium as controls. Age of medium used for competition is shown on right. Competition dynamics with other starting frequencies are shown in Fig. S2.
