Fig. 7From: Exogenous polyunsaturated fatty acids (PUFAs) promote changes in growth, phospholipid composition, membrane permeability and virulence phenotypes in Escherichia coliIncubation with PUFAs alters biofilm formation in E. coli. 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 complex (LB) and minimal media (CM9). The absorbance (OD590) was measured using a Biotek Synergy microplate reader. Shown is a representative assay from two independent experiments. Each value represents the mean and standard deviation of 8 wells. Asterisks indicate p-values determined to be less than 0.001 when compared to the no fatty acid controlsBack to article page
