Basics of Growth and the Monod Equation
There are many models of varying complexity that seek to relate specific growth rate to nutrition. The Monod equation is one such expression. It is particularly significant for this course because of its popularity, simplicity, and usefulness. While an in-depth analysis would explore the implications of the mathematics, the equation's basic precepts should be recognized easily.
Microbial populations increase until nutrients are exhausted. Analysis is aided by focus on the limiting nutrient. The Monod equation relates limiting nutrient concentration to a population's growth rate.
