A value of 
has been determined for a fermenter at its maximum practical agitator
rotational speed and with air being sparged at 0.5 l gas/l reactor volume-min. E. coli with a
of 10 mmol O₂/g-dry wt-h are to be cultured. The critical dissolved oxygen concentration
is 0.2 mg/l. The solubility of oxygen from air in the fermentation broth is 7.3 mg/l at 30∞C.
a. What maximum concentration of E. coli can be sustained in this fermenter under aerobic
conditions?
b. What concentration could be maintained if pure oxygen was used to sparge the reactor?
