Fig 5. Temporal simulations results to investigate the re-attachment of bacterial cells after dispersal.

Shown are (a) the ratio of dispersed cells that are re-attached and the cells that are detached Z(t) using τ _L = 10nM, τ _H = 70nM, η _{1 L} = 0.6/d, η _{1 H} = 4.2/d; (b) amount of re-attached cells defined by ${\eta }_2\frac{M}{k_5+M}$ and computed for different values of k ₅ i.e. k ₅ = 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7gm ⁻³ using the quorum sensing threshold value τ = 10nM and the maximum dispersal rate η ₁ = 3.6d ⁻¹.
