Transition to Quorum Sensing in a Model Bacterial Population Growing as an Attached Biofilm
(A) Spatial gradient of autoinducer created by the biofilm after 7 h of growth at two different values of AAI diffusion coefficient: (a) 10−5 cm2/s and (b) 10−6 cm2/s. The x-axis is perpendicular to the plane of the biofilm, which is positioned at x = 0.
(B) Intracellular copy numbers of TraRd and TraM averaged over 20 randomly selected bacteria versus the population density for the slower diffusion of AAI.
