The kLa of a small bubble column (2 l) has been measured as 20 h-1 at an airflow of 4 l/m in. If the rate of oxygen uptake by a culture of Catharanthus roseus is 0.2 mmol O2/g dry weight-h and if the critical oxygen concentration must be above 10% of saturation (about 8 mg/l), what is the maximum concentration of cells that can be maintained in the reactor?
