Swarming motility of P. aeruginosa (PAO1) in presence of five phenolic compounds. Swarming zone diameters of P. aeruginosa (PAO1) in presence of (A) 1/2 × MIC of methyl gallate, phloroglucinol, pyrocatechol, pyrogallol and resorcinol, (B) 16~256 µg/mL of methyl gallate. (C) Representative swarm plates incubated with the supplementation of increasing concentrations (16~256 µg/mL) of methyl gallate. Data represent the mean ± SD of triple determinations. Different superscript letters are significantly different at P < 0.05.
