Phenotypic response of PaFLR01 to fermentation products. (a) Final optical density (OD) at 500 nm and (b) pyocyanin measurements at 691 nm were taken after 48 h of incubation at 37°C. Phenotypic (c) swarming and (d) swimming assays were set at 48 h at 37°C. Area quantification of (e) swarming and (f) swimming colonies was performed with ImageJ. Dots within each boxplot indicate each biological replicate. Bdl = PaFLR01 + 20 mM 2,3-butanediol. La = PaFLR01 + 20 mM lactic acid. Pairwise T tests were performed to determine significance. *p value < 0.05; **p value < 0.01; ***p value < 0.001; ns = p value > 0.05, not significant.
