Je suis en train de faire une ébauche. Je vous laisserez mettre les images et finir. (David)
The summer was short and unfortunatly we did not assemble all the constructs necessary to see bacteria communicating through our messages in bubbles. Nevertheless, we achieved critical steps toward this goal.
In order to prove the feasibility of our project 5 main points needed to be adressed:
1. Addressing proteins to the sender bacteria outer membrane
2. Controlling the production of outer membrane vesicules
3. Addressing proteins to outer membrane vesicles
4. Fusing outer membrane vesicles of a sender population with the outer membrane of receiver cells
5. Transducing a signal from a protein in the outer membrane to a reporter gene in the receiver
We provided experimental proof for 3 out of 5 points:
Addressing proteins into the sender bacteria outer membrane
Our strategy was here to take advantage of the clyA outer membrane protein by fusing a fluorophore to N or C terminal of the ClyA protein.

FAIRE LE LIEN AVEC LE DETAIL AILLEURS DANS LE WIKI
Our clyA-mRFP1 fusion was cloned under the control of a pBAD promoter (FAIRE LE LIEN AVEC LA CONSTRUCTION DANS LA REGISTRY). We can in this microscopy pictures clearly observe the membrane localization of fluorescence.

METTRE LIEN VERS DETAILS ET METTRE LES IMAGES DES CONSTRUCTIONS ET LIEN VERS LA REGISTRY
As OMVs are very small (around 100nm) they are impossible to see with optical microscopy. As wa did not dispose of an electron microscope we tried to see

Conclusion
After a great summer of hard work, it's time to conclued on our project.
Concerning the laboratory experiment we learnt few things... The first one is that the bench work takes a lot of time, so even if our project is designed on paper, it's not so easy in the "practical" life.
Ethics is really important when a new discipline is created. In this direction, it was an evidence for our team to inclued the ethics as a part in our project. In this direction we were able to think about the synthetic biology and its applications. [Report Synthethics PDF]
About the collaboration, it was a great pleasure and it was reallu appreciable to work with other iGEM team for different part of our project (modelisation, ethics or i-phone tool). This collaboration allow us to contribute to the iGEM spirit.
