Production (µg cell−1) and comparison of β-ionone (A) and β-cyclocitral (B) compounds during different growth times in toxin-producing (LTPNA 08) and non-producing (LTPNA 01) strains of M. aeruginosa. Different letters represent significant differences in overgrowth time in each strain (for β-ionone in LTPNA 08: Kruskal–Wallis One Way Analysis of Variance on Ranks followed by Tukey post-test, p < 0.05; for β-ionone in LTPNA 01: One Way Analysis of Variance followed by Tukey post-test, p < 0.05; and for β-cyclocitral: Two Way Analysis of Variance followed by Tukey post-test, p < 0.05). * Represents a significant difference between the strains for each growth time (Student t-test, p < 0.05)
