Figure 4.

Impact of dopamine, epinephrine, norepinephrine, serotonin and cortisol on the adhesion and biofilm formation capacity of 14 strains of P. distasonis. Pd: P. distasonis. Red square indicates a significant reduction of the adhesion/biofilm formation capacities of the strains. Green square indicates a significant improvement of the adhesion/biofilm formation capacities of the strains. White square indicates no impact of the stress-induced molecules on the properties of the strains. Statistical analyses were done using the t-test. Data represent mean from triplicate for each condition (n = 3).
