Monod kinetics to determine microorganism in bioreactors

The empirical Monod equation (named after French scientist Jacques Monod) is the most common rate expression to describe the growth of microorganisms based on the substrate concentration. In this video in the bioreactor playlist, I will show how this equation bears similarity with Michaelis Menten kinetics for enzymes - similarly, you use a Ks, a "half velocity" constant at the substrate where you are at 50% maximum growth rate.

I will also discuss what assumptions you make with this equation and what other equations you want might to consider if you take inhibition into account. At the end of the video there is an exercise where you can calculate the maximum growth rate using the equations provided.

Thank you so much! Ive been strugling trying to figure so many equations out but this really makes sense finally. Thank you!

Thanks for adding the newer models! my outdated textbooks don't even cover those in PhD level courses

[muffinfighter]

Thank you! Very comprehensively and understandably explained!

Good evening! Thanks so much!! How do I go with "Mathematical modelling of anaerobic bioreactor for production of methane from domestic wastes?"

greetings prof, i want to ask a question. do attached growth media (plastic kaldness media) increase growth rate?

got my data for the lab i did, the problem is the substrate concentration (glucose) decreases over time while specific growth rate increases. I know glucose will decrease as the microbe uses glucose. When plotting the graph, it looks really bad as specific growth rate increases but substrate concentration decreases. What did i do wrong?
