Consider a 1000-l CSTR in which biomass is being produced with glucose as the substrate. The microbial system follows a Monod relationship withn µ_m = 0.4 h^-1 , K_S = 1.5 g/l (an unusu ally high value), and the yield factor Y_X/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?
