Incubation with exogenous fatty acids alters biofilm formation in Pseudomonas aeruginosa. Overnight cultures were pelleted, washed, resuspended in appropriate media and inoculated onto microtiter plates (starting OD ~ 0.1) in octuplet. Each culture was grown in the presence of 300 μM of the indicated fatty acids. After 24 h incubation, the biofilm assay by O’Toole was performed in media buffered at two pH levels (5.5 and 7.4). The absorbance (OD590) was measured using a Biotek Synergy microplate reader. Each value represents the mean and standard deviation of 8 wells. Asterisks indicate p-values determined to be less than 0.008 when compared to the no fatty acid controls
