A culture of Rhizobium is grown in a chemostat (100 m³ bioreactor). The feed contains 12 g L⁻¹ sucrose, Ks for the organism is 0.2 g L⁻¹ and μₘ = 0.3 h⁻¹.

A culture of Rhizobium is grown in a chemostat (100 m³ bioreactor). The feed contains 12 g L⁻¹ sucrose, Ks for the organism is 0.2 g L⁻¹ and μₘ = 0.3 h⁻¹.

The flow rate required to result in steady‐state concentration of sucrose as 1.5 g L⁻¹ in the bioreactor will be
A 15 m³ h⁻¹
B 26 m³ h⁻¹
C 2.6 m³ h⁻¹
D 150 m³ h⁻¹

If Yₓ/ₛ = 0.4 g g⁻¹ for the above culture and steady‐state cell concentration in the bioreactor is 4 g L⁻¹, the resulting substrate concentration will be
A 2 g L⁻¹
B 8 g L⁻¹
C 4 g L⁻¹
D 6 g L⁻¹
