Substrate Consumption in a Particular Immobilized Cell System

Question

Consider the plots of r vs. S below (labeled “1” and “2”), sketched for substrate consumption in a particular immobilized cell system subject to substrate inhibition. In one case the rate of substrate consumption is plotted as a function of average substrate concentration in the pores (S_pore), and in the other case the rate is plotted as a function of the bulk substrate concentration (S_b). 

Within the range of substrate concentration shown, specify the value of S_b – and corresponding value of S_pore  - at which there are no mass transfer limitations, or state that no such conditions exists.

Summary

This question belongs to bioreactors in biotechnology and discusses about substrate consumption in a particular immobilized cell system subject to substrate inhibition.
