Competition phenotypes of two species simulations. a There is no growth if species are unable to grow under the given conditions, e.g. they are incapable of quorum sensing; b stable coexistence of two different cell types; c exclusion of a less fit species by a fitter one; d collapse of a community. Blue lines indicate the cell numbers of the first (in case of b, c, d WT) species and the red lines the cell number of the other species as a function of time (in simulation steps). The small inserts show the population on the two dimensional longitudinal track in the time points indicated by the arrows. Blue and red dots represent the positions of agents from different species
