Figure 2. Ethanol increases c-di-GMP levels in P. aeruginosa strain PA14 WT but not in a ΔwspR mutant.

c-di-GMP levels from cultures grown on swarm plates without (black) or with 1% ethanol (grey) were measured by LC-MS. Error bars represent one standard deviation (*,p<0.05, N = 5); ns, not significant).
