A two-stage chemostat system is used for production of
secondary metabolite. The volume of each reactor is 0.5 m3; the flow
rate of feed is 50 l h- 1. Mycelial growth occurs in the first
reactor; the second reactor is used for product synthesis. The concentration of
substrate in the feed is 10 gl-1. Kinetic and yield parameters for
the organism are:
Assume that product synthesis is negligible in the first
reactor and growth is negligible in the second reactor. Determine cell
concentrations entering the second reactor.

The hydrolysis of phosphoenolpyruvate proceeds with a DG'° of about –62 kJ/mol. The greatest contributing factors to this reaction are the destabilization of the reactants by electostatic repulsion and stabilization of the product pyruvate by:
