Q. Which one of the following can NOT be a limiting substrate if Monod’s growth kinetics is applicable?

(A) Extracellular carbon source

(B) Extracellular nitrogen source

(C) Dissolved oxygen

(D) Intracellular carbon source

Ans: Intracellular carbon source

Solution:

In Monod’s growth kinetics, the rate of microbial growth is described by the Monod equation, which considers the specific growth rate of a microorganism as a function of the concentration of the limiting substrate. The limiting substrate is the essential nutrient that is in the lowest concentration and restricts the growth of the microorganism.
