Modelling
In order to understand the behaviour of our parts, we computationally modelled them by encoding biochemical networks in SBML and simulating them using COPASI.
Calcium carbonate
For more details, please see Calcium carbonate precipitation via urease expression.
Flux balance analysis
In order to inform our calcium carbonate part design, we performed flux balance analysis to identify pathways which indirectly lead to urea hydrolysis.

Biochemical network in SBML
We wrote a computational model of our calcium carbonate system in SBML and simulated it in COPASI. The graph below shows that carbonate increases over time, as desired.

Filamentous cells

Biochemical network in SBML
We wrote a computational model of our filamentous cell system in SBML and simulated it in COPASI. The graph below shows that FtsZ ring formation is low when yneA is overexpressed.
