The effect of IAN on P. aeruginosa virulence

ABSTRACT: Intercellular signal indole and its derivative hydroxyindoles inhibit Escherichia coli biofilm and diminish Pseudomonas aeruginosa virulence. However, indole and bacterial indole derivatives were unstable in microbial community due to the widespread of diverse oxygenases that could quickly degrade them. Hence, we sought to identify novel non-toxic, stable, and potent indole derivatives from plant sources for inhibiting biofilm formation of E. coli O157:H7 and P. aeruginosa PAO1. Here, plant auxin 3-indolylacetonitrile (IAN) was found to inhibit biofilm formation of both E. coli O157:H7 and P. aeruginosa without affecting its growth. IAN inhibited biofilms more effectively than indole for both E. coli and P. aeruginosa. Additionally, IAN decreased the production of virulence factor pyo
