Surface pressure increase after injection of fengycin under a DPPC monolayer previously compressed at a defined initial surface pressure. Subphase is a 10 mM Tris, 150 mM NaCl at pH 7.4. Temperature is 30°C. Fengycin is injected into the subphase under the DPPC monolayer at a defined position in one step to a final concentration of 27.5 × 10−7 M. The line represents the linear regression that best fits the experimental data. The intersection with the abscissa estimates the exclusion pressure (Πex).
