Figure 1. Ethanol represses swarming and stimulates biofilm formation by P. aeruginosa.

Figure 1

A. P. aeruginosa strain PAO1 attachment to the bottom of a polystyrene plastic well after 6 hours in medium with and without 1% ethanol (EtOH). B. P. aeruginosa strain PA14 attachment to plastic as assessed by quantification of microcolonies per field in wells containing medium with or without ethanol for 7 h. Error bars represent the standard deviation (p<0.01 as determined by a student's t-test, N = 12). C. P. aeruginosa strain PA14 swarming in the absence and presence of 1% ethanol. Images are representative of results in more than ten independent experiments.
