Distinct colony morphologies are observed among evolved isolates from different time points of the experimental evolution
ON cultures of the ancestor and evolved isolates from populations 3, 4, 6, and 7 at transfer 12, 18, and 30 were spotted on LB agar (1.5%) and imaged after incubation for 48 h at 30°C using a stereomicroscope. Ancestor represents B. subtilis DK1042. Each colony is representative of at least three replicates. Scale bar = 5 mm.
