Values of Spore and η Optimal Bulk Substrate Concentration

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). 

At the optimal bulk substrate concentration (i.e., the value of S_b corresponding to the maximum rate of substrate consumption), specify the values of S_pore and η.

Summary

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