Model analysis

Assumptions

  • Michaelis Menten Assumptions (see drug kinetics model) have been applied in the kinetics of consumption of enzyme and substrate
  • Effects of competition and induction can be represented by probabilistic variables (u and v) and are directly dependent on the rate of consumption of any given substrate S_i within the mixture
  • More details about assumptions made for each individual variable are described in the paper.



Predictions

  • In a mixture of substrates, glucose is always used up first by the culture, and then any other secondary source present in the medium.
  • The time length of the primary and secondary exponential phases of growth in the biomass depend on the initial concentration of carbon sources.
  • This will help to predict the switching point between two sources.
  • In our project:
    • The primary Carbon source: Provides repression of the CRP promoter and delays the start of the encapsulation phase (Module 2)
    • The secondary Carbon Source: Will power the system once the primary source has been used up. Finding the best secondary carbon source can help us draw a relationship with the output yield of colanic acid.
