Cell density-dependent expression of the diol synthase operon. a Time course of oxylipin production during the culture growth. Oxylipins started to be produced at the late exponential phase (4 h, OD~0.6). Then, the amount of oxylipins increased around 50 times in approximately 2 h. b Time course of β-galactosidase (β-gal) activity in PAO1 (pDSp-lacZ) and ΔDS (pDSp-lacZ) grown in the presence of 1 mg mL−1 of oleic acid (OA). The diol synthase operon was poorly induced in ΔDS (pDSp-lacZ). Means and s.d. are from three independent experiments
