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. What is the overall
substrate conversion?
