Statistics of correlated percolation in a bacterial community

Statistics of mutant ΔtrkA strain.

(A) We progressively incorporate into the model the on-cell fraction ϕ = 0.13 (light red), the exponential decay of ϕ in space with lengthscale λ = 7 cells (dark red), and the variability σϕ = 0.1 across lattices (green); N = 103 lattices for each. Resulting P(n) is a power law (green) despite the fact that 0.13 is far below the critical fraction . (B) P(n) from ΔtrkA data is a power law whose exponent is consistent with the model (N = 7 biofilms).
