English: Simulation of the producer-facultative cross-feeder community growth illustrating that the cells that are closer to interspecific cells grow better than the cells that are further away from the interspecific cells. However, given the weaker interdependence the cells growing further away from their interspecific partner grow better than when strongly interdependent. Mixing is thus reduced. Low by-product toxicity scenario. Initial conditions: two clonal microcolonies were seeded 1∶1 with either producer (red) or facultative cross-feeder cells (blue). Light red and dark red cells were seeded 1∶1 on the left and right side, respectively, of the producer microcolony. Dark blue and light blue cells were seeded 1∶1 on the left and right side, respectively, of the cross-feeder microcolony. Boundaries on the sides of the domain are permeable to the by-product and non cyclic.
