In our modeling efforts, we basically focused on three thing:

1. Gene Network
2. C.Crescentus's Characteristics
3. Physical Performance of Color Mangling

All we are trying is to give a insight into the system we are studying, to solve problems like:

1. How will different colors effect with each other?
2. Is our gene circuit design plausible?
3. Can we successfully integrate the E.coli and C.Crescentus?

So, we mainly model on four levels:

• Colony level
• Cellular level
• Gene level
• Physical level
