The Monod equation is commonly used in environmental engineering.
This page was last edited on 8 Februarymonod equation derivation From Wikipedia, the free encyclopedia. Specific growth rate plotted respect to initial substrate concentration in a batch system.
Overview of some theoretical approaches for derivation of the Monod equation.
Equation 6 describes the condition where substrate utilization is monod equation derivation to substrate concentration i. Views Read Edit View history. This container initially contains a known growth substrate concentration S.

Lennox, and Rockford J. Monod equation derivation with derication Michaelis—Menten equation graphical methods may be used to fit the coefficients of the Monod equation: Equation 7 describes the condition where substrate utilization rate is a constant i. The Monod equation is a mathematical model for the growth of microorganisms.

The container is well mixed and therefore the dissolved oxygen concentration Derrivation does not become a limiting factor for microbial growth. By combining equations 2 and 3 we can write the following expression for time-rate-of-change of biomass:. For example, it is used in the activated sludge model for sewage treatment.
Similarly, by combining equations 1 and 3 we can write an expression for substrate utilization rate. They will differ between species and based on the ambient environmental conditions.
The Monod equation is: The yield coefficient and monod equation derivation specific growth rate used to develop three types of microbial growth kinetic relationships; Monodfirst order monod equation derivation zero order kinetics.
All articles with unsourced statements Articles with unsourced statements from Derivatino The most widely used expression for describing specific growth rate as a function of substrate concentration is attributed to Monod The rate of substrate utilization is related to the specific growth rate as follows: When the yield coefficient, being the monod equation derivation of mass of microorganisms to mass of substrate utilized, becomes very large this signifies that there is deficiency of substrate available for utilization.
It is named for Jacques Monod who proposed using an equation of this form monod equation derivation relate microbial growth rates in an aqueous environment to the concentration of a limiting nutrient.
