This page was last edited on 8 Februaryat The most widely used expression for describing specific growth rate as a monod equation derivation of substrate concentration is attributed to Monodmonos The Monod equation is a mathematical model monod equation derivation the growth of microorganisms. Retrieved from equahion https: The Monod equation is: The container is well mixed and therefore the dissolved oxygen concentration O2 does not become a limiting factor for microbial growth.
This container initially contains a known growth substrate concentration S.
Similarly, by combining equations 1 and 3 we can write an expression for substrate utilization rate. The Monod equation is commonly used in environmental engineering. For example, it is used in the activated sludge model for sewage treatment. A conceptual plot of microbial cell concentration vs time ,onod the batch system is called a growth curveas shown in Figure monod equation derivation.
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. Equation 5 describes monod equation derivation Monod kinetic relationship for substrate utilization. All articles with unsourced statements Articles with unsourced statements from January The yield coefficient and the specific growth rate used to develop three types of microbial growth kinetic relationships; Monodfirst order ,and zero order kinetics.
They monod equation derivation differ between species and based on the ambient environmental conditions.
It is named for Jacques Monod who proposed using an equation of this monod equation derivation to dwrivation microbial growth rates in an aqueous environment to the concentration of a limiting nutrient. Equation 7 describes the condition where substrate utilization rate is a constant i. Archived from the original PDF on December 29, Annual Review of Microbiology. On-line monod equation derivation estimation, adaptave state estimation and adaptave control of fermentation processes.

Growth and Kinetics” PDF. Monod equation derivation rate of substrate utilization is related to the specific growth rate as follows: Equation 6 describes the condition where substrate utilization is proportional to substrate concentration i.
