The same culture (with the m and K, values as computed above) is cultivated in a 10 L chemostat being operated with a 50 mL min-1 sterile feed containing 50 g L-1 of substrate. Assuming an overall yield coefficient of 0.3 (g- DCW) (g- substrate), the respective values of the outlet biomass and substrate concentrations are
