Solution
The specific growth rate according to Monod kinetics behaves in the following ways:
-
Increases with increasing substrate concentration: This is true up to a certain point. As the substrate concentration increases, the specific growth rate also increases because there are more resources for the organism to grow.
-
Decreases with increasing substrate concentration: This is not typically true. The growth rate usually increases with substrate concentration, but it can decrease if the concentration becomes too high and inhibits growth.
-
Reaches a maximum at high substrate concentrations: This is true. The growth rate will increase with substrate concentration until it reaches a maximum, known as the maximum specific growth rate (µmax). After this point, further increases in substrate concentration will not increase the growth rate.
-
Is independent of substrate concentration: This is not true. The specific growth rate is dependent on the substrate concentration.
-
Is zero if substrate concentration is zero: This is true. If there is no substrate, there is nothing for the organism to use for growth, so the growth rate is zero.
-
Is half-maximal when the substrate concentration equals Ks: This is true. Ks is the substrate concentration at which the growth rate is half of its maximum value. This is a characteristic of Monod kinetics.
