Figure 7. Interfacial free energy of aggregation of P. aeruginosa PA14 strains.

Figure 7

(A to C) Components: Lifshitz-Van der Waals (LW ΔG) and acid-base (AB ΔG) and total interfacial free energy (Total ΔG) of aggregation of PA14 strains before and after DNase I treatment. Error bars represents standard deviations from the mean (n = 3). Asterisks and hash indicate statistically significant (p<0.05) differences in the free energy of aggregation in comparison to DNase I treated wildtype and ΔphzA-G strain regardless of DNase I treatment respectively.
