Metabolic changes in pyomelanin-producing mutants of P. aeruginosa.

A. Proportion of living bacteria after 24 h of incubation in minimal media M63 supplemented with 0.05% of tyrosine as the sole C-source as described before (see Supplementary Information). Ratio of means ± SEM from at least 3 independent experiments; two-sided Student’s t-tests; NS, P > 0.05; ***, P < 0.001.

B. Bacterial growth on M63 plates supplemented with 0.1% geraniol as the only C-source and incubated for 48 h at 37°C followed by 10 days at 30°C.
