Fig. 2: Impact of adjacent colonies on each other’s growth kinetics.

a Increasing number of colonies were inoculated on standard Petri dishes (1,2,3,4, and 6 colonies per plate) (sample sizes in order: 4,6,9,12,12). Pictures shown were taken 13 days after inoculation, green circles indicate area after 1 day and magenta circles indicate area after 20 days (Scale bar represents 1 cm). b Simulation of the above experiment. Green indicates the colony area after 1 day, white after 13 days, and magenta after 20 days. c Kinetics of colony area by colony number on the plate is shown. Experimental data is shown with markers and simulations with a solid line. Simulation results are scaled 55.6 pixels to 1 mm².
