Cell adhesion and fluid flow jointly initiate genotype spatial distribution in biofilms

Model validation: Distribution of correlation lengths for matrix-producing strains.
Estimated theoretical (full line) and experimental (dashed line) correlation length distributions using kernel density estimation (KDE) techniques. The symbols represent the experimental distribution prior to smoothing estimations. Each color represents a range of colonizing cell densities: green, 10−1 cells/μm2 for the model and high density experimental data (cluster of data around 10−1 cells/μm2 in Fig 2); blue, 10−2 and 2.15x10-2 cells/μm2 for the model and intermediate density experimental data (7x10-3 < ρ0 < 3x10-2 cells/μm2); and red, 10−3 and 2.15x10-3 cells/μm2 in the model and low density experimental data (ρ0 < 5x10-3 cells/μm2).
