Characterization of Quorum Quenching Device I

Fig.1 Quorum quenching results

We did the experiment XIX to test the quorum quenching ability of QQ Device I (BBa_K2548000 + BBa_K2548006) and QQ Device II (BBa_K2548000 + BBa_K2548007), and the result is shown below. E. coli DH5a transformed with sensor device I was induced for 3 hours in the supernatant of cells containing empty RPG plasmid, QQ device I, and QQ device II after they were induced by C4-HSL for 4 hours. In Fig. 1, the control group with empty RPG plasmid shows higher GFP concentration than the culture of QQ device I and QQ device II, indicating that C4-HSL was consumed by the two devices. The GFP concentrations reduced 18.5% and 20.9% for device I and device II compared with control group respectively, implying that QQ device I had better C4-HSL degradation ability.
