Initially a known concentration X of viable microbial cells i. Specific growth rate plotted respect to monod equation derivation substrate concentration in a batch system. The Monod equation is commonly used in environmental engineering.

On-line parameter estimation, adaptave state estimation and adaptave control of fermentation processes. Environmental engineering Civil engineering Sewerage.

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

The rate of substrate utilization is related to the specific monod equation derivation rate as follows: Equation 6 describes the condition where substrate utilization is proportional to substrate concentration i. As with the Michaelis—Menten equation graphical methods may be used to fit the coefficients of the Monod equation: Microbial growth and substrate utilization in a well mixed batch container.


For example, it is used in the activated sludge model for sewage treatment. The yield monod equation derivation and the specific growth rate used to develop three types of microbial growth kinetic relationships; Monodfirst order ,and zero order kinetics.

Equation 7 describes the condition where substrate utilization rate is a constant i. All articles with unsourced statements Articles with unsourced statements from January Retrieved from ” https: It is named for Jacques Monod monod equation derivation proposed using an equation of this form to relate microbial growth rates in an aqueous environment to the concentration of a limiting equatin.

Louvain la Neuve, Belgium: Archived from the original PDF on December 29, Growth and Kinetics” PDF. By using this site, you agree to monod equation derivation Terms of Use and Privacy Policy.

The container is well mixed and therefore monod equation derivation dissolved oxygen concentration O2 does not become a limiting factor for microbial growth. Equation 5 describes the Monod kinetic relationship for substrate utilization. By combining equations 2 and 3 we can write the following expression for time-rate-of-change of biomass:. Lennox, and Rockford J.

A conceptual plot of microbial cell concentration vs time for the batch system is called a growth curveas shown in Monod equation derivation 2. This container initially contains a known growth substrate concentration S.


The most widely used expression for describing derivvation growth rate as edrivation function monod equation derivation substrate concentration is attributed to Monod The Monod equation is a mathematical model for the growth of microorganisms. 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 monod equation derivation utilization.

From Wikipedia, the free encyclopedia. They will differ between species and based on the ambient environmental conditions.
