Abioreactor is running at steady state. it was determined that under this condition, ka = 15/ℎ. when air is pumped into the bioreactor, a yeast can be grown with, qa = 5 mmol/g. h. the critical dissolved oxygen concentration = 0.3 mg/l (the lowest cl for the yeast to grow). the oxygen solubility for the culture running in the bioreactor is 9 mg/l. what is the maximum concentration of the yeast this bioreactor can achieve? what is the maximum concentration when pure oxygen is used for running the bioreactor?
