2. E. coli is to be cultivated under aerobic conditions. A value of kla=32.5hr1 was measured at maximum agitator rotational speed with air being sparged in the reactor at a rate od 0.75L air/ L reactor volume.min. E. coli have a specific oxygen uptake rate of 11.5mmolO2/g.hr. The saturation concentration of oxygen in the fermentor broth at 30C is 0.228mmol/L and the dissolved oxygen concentration is maintained at 0.006mmol/L. Calculate the maximum cell concentration that can be achieved under these conditions. Points
