To achieve this innovative project, we have decided to rely on a genetic structure that allows a specific sequence of lighting (Firt In - First Out behaviour) to occur. The models designed have shown that simply adding a negative feedback from a lighting gene to the first activator will not yield oscillations ! Therefore, we have proposed to induce a necessary delay, through a synchronization process among the population, as represented below :

Synthetic biology is a new science, so we have to chance to set the base of synthetic biology. Hence our motto : '''Innovation'''! Therefore, we put a lot of efforts in proposing an original approach while building our system and analysing it.

Up to now, we managed to build biologically a system that is to behave as a FIFO, and designed the oscillatory system. We also foresaw improvments that would enhance our system performances, among which introducing a synchronization application.

To achieve this incredible project, we relied on a well characterized genetic structure that allows a specific sequence of fluorescent proteins expression to occur in a First In - First Out order. This FIFO behaviour enables us to define a rich color encoding of day time. An additional negative feedback loop generates clock oscillations!

The BacteriO'Clock

Have you ever dreamt of a new way of thinking everyday life objects ? Be sure, this will come true, under the form of our BacteriO'Clock ! A simple test tube which contains our modified bacteria will give you the time, directly from living organisms. The hours of the day are color-coded and oscillations ensure the repeated periodic behaviour.

To achieve this incredible project, we relied on a well characterized genetic structure that allows a specific sequence of fluorescent proteins expression to occur in a First In - First Out order. This FIFO behaviour enables us to define a rich color encoding of day time. An additional negative feedback loop generates clock oscillations!

Based on in-depth studies and experimentally measured parameters we develope models that show that this system is not likely to oscillate, and indicate ways to improve the initial design. In particular, this can be achieved by HSL production that enforces a necessary delay and provides an elegant cell synchronization mechanism :
