What is Monod curve?
What is Monod curve?
The Monod equation is a mathematical model for the growth of microorganisms. 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.
What does Monod equation describe?
The Monod equation is frequently used to describe the stimulation of growth by the concentration of nutrients as given by: (4.1) µ µ where, µ=specific growth rate, h−1 defined as (1/X) (dx/dt) µmax=maximum value of μ, h.
What is by meant microbial kinetics?
Microbial growth kinetics, i.e., the relationship between the specific growth rate (μ) of a microbial population and the substrate concentration (s), is an indispensable tool in all fields of microbiology, be it physiology, genetics, ecology, or biotechnology, and therefore it is an important part of the basic teaching …
What does the Monod model predict?
The monod model predicts that the specific growth rate.
What does KS mean in Monod?
CA and CB denote substrate A and biomass B concentration in the liquid, respectively. k is maximum specific growth rate and KS is Monod (saturation) constant. Y is growth yield coefficient (kgB/kgA).
What are Monod parameters?
Michaelis-Menten or Monod model which was proposed by Jacques Monod in 1942 is one of the model used to estimate the specific growth of microalgae. Parameters consist in the Monod model widely influence in the microalgae cultivation system.
How does a Chemostat work?
A chemostat (from chemical environment is static) is a bioreactor to which fresh medium is continuously added, while culture liquid containing left over nutrients, metabolic end products and microorganisms are continuously removed at the same rate to keep the culture volume constant.
What is substrate limitation?
A nutrient used in the growth of microorganims in a concentration that restricts or limits the rate of growth. Where another nutrient is the limiting substrate, other undesirable bioproducts may result or there may be a poor growth of cells…. …
What are the four primary parameters that are used to describe bacterial growth kinetics?
It has been determined that in a closed system or batch culture (no food added, no wastes removed) bacteria will grow in a predictable pattern, resulting in a growth curve composed of four distinct phases of growth: the lag phase, the exponential or log phase, the stationary phase, and the death or decline phase.
What is chemostat example?
A chemostat is defined as a steady-state bioprocess, where a microbial culture is continuously supplied with nutrients at a fixed rate and concomitantly harvested to keep the culture volume constant. From: Methods in Enzymology, 2019.
What are the basic principles of chemostat cultivation?
The principle of chemostat culture is based on the relationship between the specific growth rate and a limiting nutrient concentration that regulates the growth rate in such a way that it matches a preset constant dilution rate.
How are Monod kinetics used in microbial growth?
Monod kinetics Kinetics of microbial cell growth as a function of substrate concentration proposed by Jacques Monod and widely used to understand growth-substrate relationships. [Pg.905]
When to use Monod kinetics in biocatalyst?
The Monod kinetic model can be used for microbial cell biocatalyst and is described as follows A limiting case of Monod kinetics has Ks = 0 so that cell growth is zero order with respect to substrate concentration. Rework Example 12.7 for this situation, but do remember to stop cell growth when S = 0.
Which is the limiting case of Monod kinetics?
A limiting case of Monod kinetics has Ks = 0 so that cell growth is zero order with respect to substrate concentration. Rework Example 12.7 for this situation, but do remember to stop cell growth when S = 0. Compare your results for X and p with those of Example 12.7. Make the comparison at the end of the exponential phase. [Pg.460]
How is the Monod equation used in science?
The Monod equation is frequently used to describe the stimulation of growth by the concentration of nutrients as given by: (4.1) µ µ µ = µ max S / ( K s + S) where, µ=specific growth rate, h −1 defined as (1/X) (dx/dt) µ max =maximum value of μ, h −1. KS =saturation constant, gL −1 at μ max /2.
