A 10,000 liter (of liquid) bioreactor contains 5 g / L of growing cell

1.	A 10,000 liter (of liquid) bioreactor contains 5 g / L of growing cells qO2 = 20 mmoles O2 / (g cells hr) DT = 2 m, DI = 1 m, (6 – blade turbine agitator) x 3 blades and CL = 1 mg O2/L. Calculate OUR.(a) 200 mmoles O2 / (g cells hr)(b) 250 mmoles O2 / (g cells hr)(c) 100 mmoles O2 / (g cells hr)(d) 150 mmoles O2 / (g cells hr)The question was asked during an interview.My enquiry is from Measurement of KLa in chapter Mass Transfer of Bioprocess Engineering
Answer» Right option is (c) 100 mmoles O2 / (g cells hr) EXPLANATION: OUR = X QO2 = (5 g / L) (20 mmoles O2 / (g cells hr)) = 100 moles O2 / (g cells hr).
