| Outline of Final Research Achievements |
Bubble column bioreactors are operated by dispersing bubbles in liquid phase. Quantitative evaluation of shear rate and electrostatic property of bubbles is of importance to rationally design various separation and reaction processes using bubble columns. In this work, the shear rate generated in various types of external loop airlift bubble column was estimated on the basis of the release kinetics of the hydrophilic dye molecules from liposomes. Furthermore, the electrostatic property of bubbles was also evaluated on the basis of membrane permeability of various charged liposomes suspended in the bubble columns.
