A gradually slowing travelling band of chemotactic bacteria.
A model for describing the motion of chemotactic bacteria in a capillary tube containing substrate is treated. Chemotactic substrate threshold effects are included in the chemotactic response coefficient. The ratio of the substrate threshold, ST, to the substrate level far ahead of the travelling band, S infinity, is used as a small parameter in developing an asymptotic solution of "near travelling wave" form.
