Annual Monod equation derivation of Microbiology. The most widely used expression for describing specific growth rate as a function of substrate concentration is attributed to Monod For equxtion, it is used in the activated sludge model for sewage treatment.

Microbial Growth

monod equation derivation Initially mobod known concentration X of viable microbial cells i. Similarly, by combining equations 1 and 3 we can write an expression for substrate utilization rate. As with the Michaelis—Menten equation graphical methods may be used to fit the coefficients of the Monod equation: The Monod equation is a mathematical model for the growth of microorganisms.

Specific growth rate plotted respect monod equation derivation initial substrate concentration in a batch system.


Overview of some theoretical approaches for derivation of the Monod equation.

Lennox, and Rockford J. Archived from the original PDF on December 29, Growth and Kinetics” PDF.

It is named for Jacques Monod who proposed using monod equation derivation equation of this form to relate microbial growth rates in an aqueous environment to the concentration of monod equation derivation limiting nutrient. Retrieved from ” https: The Monod equation is commonly used in environmental engineering. On-line parameter estimation, adaptave state estimation and adaptave control of fermentation processes. Microbial growth and substrate utilization in a well mixed batch container.

From Wikipedia, the free encyclopedia. The container is well mixed and therefore the dissolved oxygen concentration O2 does not become a limiting factor for microbial growth.

Louvain la Neuve, Belgium: This container initially contains a known growth substrate concentration S. By using this site, you agree to the Terms of Use and Privacy Policy. Equation 5 describes monod equation derivation Monod kinetic relationship for substrate utilization.

Monod equation – Wikipedia

The rate of substrate utilization monod equation derivation related to the deruvation growth rate as follows: When the yield coefficient, being the ratio of mass of microorganisms to mass of substrate utilized, becomes very large this signifies that there is deficiency of substrate available for utilization.


The yield coefficient monod equation derivation the specific growth rate used to develop three types of microbial growth kinetic relationships; Monodfirst order ,and zero order kinetics.

Environmental engineering Civil engineering Sewerage. Equation monod equation derivation describes the condition where substrate utilization is proportional to substrate concentration i. This page was last edited on 8 Februaryat They will differ between species and based on the ambient environmental monod equation derivation.

By combining equations 2 and 3 we can write the following expression for time-rate-of-change of biomass:. Views Read Edit View history. Equation 7 describes the condition where substrate utilization rate is a constant i.
