DL inhibits the production of EPS and extracellular phospholipase. A: Preformed C. albicans SC5314 biofilms were treated with 0, 16, 32 and 64 µg/mL of DL for 24 h before the determination of EPS production in biofilms through phenol-hydrazine sulfate method. B: Fungal cells were added on egg yolk emulsion agars supplemented with 0, 16, 32 and 64 µg/mL of DL. After 4-day incubation at 37 °C, the diameter of colony (d₁) and that of colony plus precipitation zone (d₂) were measured. Pz means d₁/d₂, while higher Pz indicates lower phospholipase production. **, p < 0.01
