Induction by the Supernatant of a LuxI Producing Culture

The production of an inducer for the 3OC6-HSL and LuxR dependent promoter R0062 by LuxI could be shown using the supernatant of a culture containing E. coli cells constitutively expressing LuxI to induce the 3OC6-HSL sensor construct with the reporter sfGFP in another culture.

Background information

Experimental Setup

Results

Figure 1: Dose-response curve LuxI producer supernatant The supernatant culture of E. coli cells in LB medium constitutively expressing LuxI was used in different dilutions with fresh LB medium as growth medium for E. coli cell containing a construct expressing sfGFP under a Plux promoter and constitutively expressing the regulator LuxR. Fluorescence/OD₆₀₀ of sfGFP was measured 6 h after inoculation.
