#Section 5: Bioprocess Engineering and Process Biotechnology

Consider a 1000-l CSTR in which biomass is being produced with glucose as the substrate. The microbial system follows a Monod relationship withn ยตm = 0.4 h-1 , KS = 1.5 g/l (an unusu ally high value), and the yield factor YX/S = 0.5 g biomass/g substrate consumed. If normal operation is with a sterile feed containing 10 g/l glucose at a rate of 100 l/h. What is the specific biomass production rate (g/l-h) at steady state?

In a two-stage chemostat system, the volumes of the first and second reactors are V1 = 500 l and V2 = 300 l, respectively. The first reactor is used for biomass production and the second is for a secondary metabolite formation. The feed flow rate to the first reactor is F = 100 l/h, and the glucose concentration in the feed is S = 5.0 g/l. Use the following constants for the cells.



Determine cell concentration in the effluent of the first stage.
