Consider this schematic: [S]o F [S], x where • [S] is the concentration of growth limiting substrate •F or V' is the volumetric flow rate of S into the chemostat •V is the reactor volume •x is the biomass per unit volume (x = biomass/V) •u is the biomass growth rate •t is the residence time in the reactor (t=V/F) ·D is the dilution rate (D=F/V) • Cell growth kinetics: r,-ux a) What are the units for r,? b) Assuming sterile feed, write a steady-state material balance for x. c) Write a steady-state material balance for S. d) Make a plot of x (y-axis) and S (second y-axis) as a function of D. e) What happens if D is very large?
