Temporal Control

Engineering Approach to Temporal Control

This temporal control platform showcases our engineering approach in the E.ncapsulator project.

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.

Drylab

The first of our diauxic growth models is a cybernetic model developed by Kompala et al [1]. 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).
