Effects of QQ and QSI on the rhl system. (A) Combination effects of G1 and AiiA on PAO1-rhlA-gfp reporter strain. (B) Dose-response effects of G1 (50 µM) added with AiiA (32 µg/ml) on rhlA-gfp. (C) Effects on rhamnolipid production when tested at final concentration of 50 µM (for G1), and 32 µg/mL (for AiiA). Same amount of DMSO and buffer were used as positive control. PAO1 ΔlasIΔrhlI was used as negative control. Experiments were done in triplicate manner. Error bars are means ± SDs. *** = p < 0.001. **** = p < 0.0001, Student’s t test.
