The maximum cell concentration (g l–1) expected in a bioreactor with initial cell concentration of 1.75 g l–1 and an initial glucose concentration of 125 g l–1 is (Yx/s = 0.6 g cell/g substrate)_______
-
- 36.7 to 46.9
- 76.7 to 76.9
- 86.7 to 96.9
- None of the above
Correct Option: B
Given, Initial cell concentration, X = 1.75 g/L
Initial concentration of substrate glucose, S = 125 g/L
Given, Yield of biomass, YX/S = 0.6 g/g
Now, Concentration of biomass produced = YX/S × S = 125 × 0.6 g/L = 75 g/L
Therefore, maximum concentration of cell expected in the bioreactor = 75 + 1.75 g/L = 76.75 g/L
