Degradation of indole and 7HI by P. aeruginosa. Pseudomonas aeruginosa degrades 0.5 mM indole (A) and 0.5 mM 7HI (B) in LB. The initial turbidity of cells was 1.0 at 600 nm. Closed square data (▪) are from live cells, open square data (□) are from autoclaved cells (dead cell control) and open circle data (○) are from live cells that lack added indole or 7HI. Each experiment was performed using two independent cultures, and one representative data set is shown.
