Figure 3. Bioluminescence induction by OHHL and quorum-sensing superagonist 11n in V. fischeri.
a) V. fischeri ES114 (Δ-luxI) streaked onto agar plates containing either no compound (control), 0.5 µM OHHL (1), or 0.5 µM superagonist 11n and grown for 8 h and imaged. b) Identical plates from panel a imaged for luminescence using a CCD imager.
