We know that the specific growth rate as a function of nutrients may be the form of monod models. For light and temperature, many people have proposed different types of models. What if we want to relate the growth rate to CO2/pH? Any ideas?

Gerd:
Thank you very much for your answer. Unfortunately our university library doesn't provide us with most of springer articles. Is there any way to send me the paper you're talking about?
Thanks
Dear Hossein,
If CO2 is the limiting substance in your growth, it is conceivable that you can develop a model. If it is not, then the influence of CO2 concentration may be second to other factors such as light intensity or nitrogen concentration.
The distribution of CO2 as carbonate, bicarbonate or free CO2 is dependent on the medium pH and these depend on the composition. The overall concentration is dependent on the gas transfer to the medium and the CO2 uptake by the cells.
As Gerd implicitly suggests, it would be wise to check the literature for prior attempts on modeling CO2 consumption by microalgae. By the way, the first author of the paper has made it available here on ResearchGate.
This could be interesting, please post updates on the development of your model.
Best regards,
