Q70
A bacterial culture having a specific oxygen uptake rate of 5 mmol O2 (g DCW)-1 hr-1 is being grown aerobically in a fed-batch bioreactor. The maximum value of the volumetric oxygen transfer coefficient is 0.18 s-1 for the stirred tank bioreactor and the critical dissolved oxygen concentration is 20% of the saturation concentration (8 mg mL-1). The maximum density to which the cells can be grown in the fed-batch process without the growth being limited by oxygen transfer, is approximately
A.
14 g L-1
B.
26 g L-1
C.
32 g L-1
D.
65 g L-1
