Gross swarm morphology is affected by nutrients, basal medium. Colony morphologies after 1d on A) FW-succinate-NH4Cl and B) FW-casamino acids. C) After 3d on FW-succinate-methionine, a "rare branch" phenotype was observed. D) Slower swarming on M9-succinate-tyrosine was characterized by a less well defined swarm with altered structure. Stark differences in extent and form of swarming were observed on E) FW-succinate-tryptophan and F) M9-succinate-tryptophan. G) After an extended incubation, swarms on FW-succinate-NH4Cl display a mutually repellent morphology with distinct internal and external edges.
