Self-similar dynamics of bacterial chemotaxis.
Phys Rev E Stat Nonlin Soft Matter Phys
December 2012
Colonies of bacteria grown on thin agar plate exhibit fractal patterns as a result of adaptation to their environments. The bacterial colony pattern formation is regulated crucially by chemotaxis, the movement of cells along a chemical concentration gradient. Here, the dynamics of pattern formation in a bacterial colony is investigated theoretically through a continuum model that considers chemotaxis.

Article Synopsis
- This paper explores a density-dependent reaction-diffusion equation related to population dynamics and other fields.
- A transformation simplifies the equation to an anomalous diffusion form, allowing for exact self-similar solutions.
- Results show a connection between these solutions and traveling wave solutions, with applications in biological pattern formation.
