We’ve made our entire system <b>modular</b>, where we trigger the succession of events using this control system. Here, we have tackled a drug delivery problem, but this "Black box" approach can be applied to any other system. This is our <b>novel engineering approach</b>, which is extremely <b>reusable</b> in synthetic biology.
-
We’ve made our entire system modular. Each module can essentially be pictured as a blackbox with one temporal control input and one output. Therefore, each module is linked to the next module by temporal control. Temporal control has allowed us to create a system that can be reused in other projects in synthetic biology. It is in fact a novel engineering approach that is both reusable and elegant.

In our temporal control system, we have employed 3 kinds of temporal control:

This testing construct was used to test the inducible promoters using flourescent proteins as output reporters.<br>

Production of the protein of interest is triggered by the addition of a chemical.

In our case, we have chosen IPTG. IPTG will be added when the cell density is deemed sufficient for protein production (Module 1) to begin.

*<b>Autoinduction:</b>
+
</div>
-
 
+
</div>
-
When glucose levels have fallen to nearly 0, encapsulation (Module 2) will begin automatically in response.  
+
</html>
-
 
+
-
In our case, this will allow a sufficient amount of protein production to have taken place, before the cell focuses its resources on encapsulation.
+

+

+
-
*<b>Thermoinduction: </b>
+
-
 
+
-
Genome deletion is triggered by the increase of temperature. This is the last step of the temporal control system.
+
-
 
+
-
In our case, thermoinduction was necessary, as chemical induction may be blocked by the presence of the capsule (that inhibits diffusion).

[[Image:II09_diax_wolf.jpg | left]]We have modelled autoinduction by a number of models, and we hope that experimental results will confirm which model is most applicable to our system.

<u>Wetlab</u>
-
The first of our diauxic growth models is a cybernetic model developed by Kompala et al [1]. Diauxic growth occurs when glucose is taken up preferentially instead of the secondary carbon source present. This results in an exponential growth, follow by a stationary growth phase when glucose runs out. This will be followed by another exponential growth as the cells now consume the secondary carbon source.

This model shows that glucose (S1) is used up before the secondary carbon source (S2). During this phase, the population (X) is in exponential grow until glucose (S1) runs out. This is followed by a stationary growth phase, and finally the population enters a second exponential growth phase as they start uptaking the secondary carbon source (S2).

Temporal Control


Engineering Approach to Module Integration by Temporal Control

This temporal control platform showcases our engineering approach in the E.ncapsulator project. It allows us to integrate all our modules in a simple and elegant way.

We’ve made our entire system modular, where we trigger the succession of events using this control system. Here, we have tackled a drug delivery problem, but this "Black box" approach can be applied to any other system. This is our novel engineering approach, which is extremely reusable in synthetic biology.

Conclusion

Module integration has allowed us to link all our modules together, to create a working network.

It also allows us to showcase the advantages of synthetic biology as the marriage of engineering with biology. By integrating the engineering principles of reusability and simplicity of system, we have developed this platform to program biologcal systems.
