Demonstrate

Using this project as a foundation other groups should be able to take a step further with their quorum sensing projects' design, by having the possibility of quantifying more precisely the interaction between different systems, and use it to improve their modelling. Furthermore, we took into account the time needed to produce the components of the system, generating a more realistic result. The next step must be to consider the cross talk between systems that was measured and work to minimize them, creating increasingly orthogonal circuits.

We have been successful in our initial proposition, of making a modular construct thas was capable of measuring quorum sensing interactions. Our Lux Sender system (BBa_K2771030) worked as expected, generating a Homoserine Lactone signal capable of activating a collection of quorum sensing promoters. We also established a reliable method for measuring this activity, with a ratiometric activity reporter that gives us an adimensional, robust measurement, by utilizing EYFP as a reporter and CFP as normalization control.
