Summary of experimental evolution experiments.

*Generation zero is defined as the point at which chemostat flow was initiated.
ˆA clone from this population, S6c1, has previously been reported in [18]. In that paper the clone was called g122.
We performed 24 independent experimental evolutions in chemostats under three different nutrient limitation regimes. Evolutions were performed using two different strain backgrounds that are amenable to long-term cultivation in chemostats. All strains were wildtype prototrophs.
