A bacterial culture having a specific oxygen uptake rate of 5 mmol O2 (g- DCW)^-1h-1 is being grown aerobically in a fed-batch reactor. The maximum value of the volumetric oxygen transfer coefficient is 0.18 s for the stirred tank bioreactor and the critical dissolved oxygen concentration is 20% of the saturation concentration (8 mg L^-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
