What is Monod growth?
The empirical Monod equation [44] is the most common rate expression to describe the growth of microorganisms in general and hydrogen-producing bacteria in particular.
What is Monod model Why do we use it?
Monod’s model relates the growth rate to the concentration of a single growth-controlling substrate [μ = f(s)] via two parameters, the maximum specific growth rate (μmax), and the substrate affinity constant (Ks) (the nomenclature used throughout, is listed in Table
What is Monod growth kinetics?
Monod Kinetics Specific growth rate plotted respect to initial substrate concentration in a batch system. The most widely used expression for describing specific growth rate as a function of substrate concentration is attributed to Monod (1942, 1949).
What are the assumptions of Monod model?
This is based on the assumption that the main factors affecting growth rate are transfer of substrate from the medium and the maximum growth velocity, which is that observed when no substrate limitations occur.
What is the significance of Monod constant?
It is the concentration of the limiting substrate, which provides 1/2 of the maximum specific growth rate, μ(max), of any microorganisms cultures. The physical meaning of this constant in a known literature describes it as a constant of affinity for any substrates.
What is the difference between Michaelis Menten kinetics and Monod equation?
The Monod equation has the same form as the Michaelis–Menten equation, but differs in that it is empirical while the latter is based on theoretical considerations. The Monod equation is commonly used in environmental engineering. For example, it is used in the activated sludge model for sewage treatment.
What are the limitations of Monod model?
The Monod model has 5 limitations as described by Kong (2017). The 1st limitation is observed at high substrate concentration. At high substrate concentration, the maximum specific growth rate is independent of the substrate concentration. The 2nd limitation is observed at low substrate concentration.
What is the similarity between Michaelis-Menten kinetics and Monod equation?
What is the difference between Michaelis-Menten kinetics and Monod equation?
What is the Monod model in microbiology?
The Monod equation is regarded as a kinetic model which exhibits microbe growth as a function of specific growth rate and an essential substrate concentration (Lobry et al., 1992 ). The Monod model was modified by introducing a substrate inhibition term (Drapcho, 2006):
What is the Monod equation for growth rate?
The growth rate μ of a considered micro-organism as a function of the limiting substrate concentration [ S ]. The empirical Monod equation is: Ks is the “half-velocity constant”—the value of [ S] when μ / μmax = 0.5
How does the Monod model differ from the classical growth models?
The Monod model (equation 1) differs from the “classical” growth models (74, 256, 257, 205) in the way that it introduces the concept of a growth-controlling (“limiting”) substrate.
How is the Monod equation used in Environmental Engineering?
The Monod equation is commonly used in environmental engineering. For example, it is used in the activated sludge model for sewage treatment . The growth rate μ of a considered micro-organism as a function of the limiting substrate concentration [ S ].
