Parameter search
The kinetic characterization of the reactions must be done through the search of parameters in scientific publications and other databases.
Due to the existence of various information regarding the same constant, an approximation to a single value can be done by assigning them a weight considering the similarity of the corresponding organism and environmental conditions. If you would like to see the criterias, click below.

Matlab simulation
Afterwards, all the collected data will be entered into Matlab and a contrast between the wild-type metabolism and the modified version will be studied.
If you would like to see the Matlab code, click the link below.
Model fitting
Once the interesting questions are answered (selection between B12-sensitive promoter and light-sensitive promoter, quantity of B12 necessary to keep a sustainable amount of starch while glucose availability is increased, light level required to maximize carbon fixation), measurements of various physical and chemical magnitudes must be made to adjust the model, and establish a probability of a parameter to belong in a certain range. The fitting will be made by the least- square method.
After the model
Maximize glucose availability by carbon fixation through adjustment of environmental conditions.
