Introduction
E.casso uses the communication between cells made available by quorum sensing. Quorum diffuses away from one cell to the other. Because we wanted to find out how the quorums produced by Brush E.coli diffuse in our model, we applied the reaction-diffusion system to our model and analyzed the distribution and propagation of quorums. This section investigates how the quorums diffuse from one cell to the other which will provide crucial data for our final simulation.
Objectives
Answer the following questions,
- How fast does quorum diffuse into adjacent E. coli as rapidly as we predicted?
- How does the produced quorum diffuse with respect to time and space?
- How much quorum does the source E. coli ultimately transfer to neighboring E. coli?

According to the statistics on E. coli ^1, the shape of E.coli is oval with 200nm minor axis and 2um major axis. For simulating our random diffusion system in E.casso, we simply the E.coli shape as square having equal area with the area of oval. (Fig 1a)
