If Yx/s = 0.4 g/g for the above culture and steady-state cell concentration in the bioreactor is 4 g/L, the resulting substrate concentration will be (A) 2 g/L (B) 8 g/L (C) 4 g/L (D) 6 g/L

Answer: (D) 6 g/L

Y_x/s = \frac{X}{S_0 - S}

Where:

  • = Yield coefficient
  • = Cell concentration
  • = Initial substrate concentration
  • = Substrate concentration at steady state
