Expanding Population of Chemotactic Bacteria (IMAGE)
Caption
A) Inoculating a few E. coli cells at the middle of a nutrientre-rich soft-agar plate results in the formation of a "swarm ring," which would expand across the plate, reaching the edge in ~12 hours. B) and C) The swarm ring is comprised of a dense region of pioneering cells (cyan) which uses chemotaxis to move up the gradient of chemoattracant (purple). A small fraction of pioneering cells would fall behind the swarm ring to settle and replicate in their locality (indicated as green cells), eventually reaching saturating densities (brown region in panel B).
