Summary of the mechanical role of eDNA in clinical mucoid and PAO1 nonmucoid biofilms. This collectively shows the relationship between eDNA abundance (gray) and biofilm thickness, cohesion (upper triangle spectrum) and stiffness (lower triangle spectrum). Stiffness is on the opposite end as it is inversely related to thickness and cohesion. The blue side of the spectrum indicates thick, cohesive, and flexible biofilms, while the red indicates a stiff, thin biofilm with limited cohesion.
