Direction: A bioreactor of working volume 50 m3 produces a metabolite (X) in batch culture under given operating conditions from a substrate (S). The final concentration of metabolite (X) at the end of each run was 1.1 kg m–3. The bioreactor was operated to complete 70 runs in each year.
-
What will be the annual output of the system (production of metabolite (X)) in kg per year ?
-
- 55
- 3850
- 45.5
- 77
Correct Option: B
In single run metabolite (X) concentration is =1.1 kg m–3.
Since, total number of runs = 70
Total concentration of (X) = 70 × 1.1 kg m–3 run–1
= 70 × 1.1 kg m–3 = 77 kg m–3
Now, total volume of batch culture = 50 m3.
Total amount will be = 50 m3 × 77 kg m–3
= 3850 kg per year
