The fermented broth with dense cell aggregated particles under aerobic conditions as a three phase system was simulated by inert ion-exchange resin particles and the gas holdup of such a system in an air-lift biore-actor was investigated. Based on the data taken from the simulated system and the measurement on a real yeast flock cultivation system
the correlation of gas holdup with superficial gas velocity
circulating velocity of suspended me-dium and interfering sedimentation velocity was obtained. The predicted values from correlation agreed well with experiments.
