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.
