(1 pt) If the cell yield Yx/s is 0.46 g/g, what is the steady-state concentration when the flow rate is 0.20 L/hr? (1 pt) This research showed that the primary result of substrate inhibition in a continuous culture may be process instability. Explain what might happen if you suddenly increase the substrate concentration from 30 to 60 g/L and why. 4.
