Impairment of the Bacterial Biofilm Stability by Triclosan
Figure 8
Linear regressions between bacterial diversity indexes and PC1 and PC2 scores of the Principal Component Analysis.
Each treatment is represented by its ellipse inertia and its gravity centre (CB: control, T1–5: increasing triclosan concentration). Solid line: significant linear regressions, dashed lines: non-significant linear regressions.
