Fig. 7: Growing young colonies next to an aging one.

New droplets were inoculated on and next to an aging colony after 20 days of initial inoculation. Images of the colonies formed (b, n = 4) and their simulations (a) are shown on days 1, 14, 22 (2 days after second inoculation), and 36 (16 days after second inoculation). Scale bar is 10 mm.
