If the respiratory quotient (R.Q.) for growing cells is 1.1 and the exit gas analyzer of a bioreactor shows 3%in the outlet gases; then given normal air as input to the reactor, you expect the outletconcentration to read approximately:
Select an option to attempt
Correct Answer: Option C
Explanation
Outlet O₂ percentage from RQ calculation:Given: Respiratory Quotient RQ = CO₂ produced / O₂ consumed = 1.1Exit CO₂ measured = 3%O₂ consumed:Inlet air composition: ~21% O₂, ~0.04% CO₂ (approximately)Outlet O₂:Answer: Outlet O₂ ≈ 18.3%.
