Cover Story: Surface colonization of bacteria depends on the environmental conditions. Colony dispersal of Bacillus subtilis (escape from a matured architecturally complex colony) is impeded by the presence of calcium in the medium. Interestingly, in addition to biofilm colony size, swarming and sliding are also influenced by calcium, likely due to modulating the chemical properties of surfactin. View this paper
