The flow rate required to result in a steady-state concentration of sucrose as 1.5 g/L in the bioreactor Common Data: A culture of Rhizobium is grown in a chemostat (100 m³) bioreactor. The feed contains 12 g/L sucrose, Ks for the organism is 0.2 g/L and μm = 0.3 h⁻¹. (A) 15 m³/h (B) 26 m³/h (C) 2.6 m³/h (D) 150 m³/h

Answer: (B) 26 m³/h
C_s = frac{S_f}{1 + frac{mu_m}{K_s} cdot frac{F}{V}}Where:
- Cs = Steady-state concentration of sucrose
- Sf = Feed concentration of sucrose
- μm = Maximum specific growth rate
- Ks = Saturation constant
- F = Flow rate
- V = Volume of the bioreactor
