Question

The specific growth rate of cells is independent on the concentration of nutrients in the medium.

(a) True

(b) False

I had been asked this question in homework.

I'm obligated to ask this question of Cell Growth Kinetics in chapter Homogenous Reactions of Bioprocess Engineering

Answer 1

Right choice is (b) False

To elaborate: The specific growth rate of cells is dependent on the concentration of nutrients in the medium. Often, a single substrate exerts a dominant influence on rate of growth; this component is known as the growth-rate-limiting substrate or, more simply, the growth-limiting substrate. The growth-limiting substrate is often the carbon or nitrogen source, although in some cases it is oxygen or another oxidant such as nitrate.
