| Outline of Final Research Achievements |
Mass culture of aerobic microorganisms is in need of damage to them and taking in much oxygen to the tank. Mixer with Stacked Elements impeller (MSE impeller) has a honeycomb structure that is made of stainless steel plate. As it has a larger surface area and better shear property than conventional impeller (Disk turbine impeller), the application of bioreactor to mass culture of aerobic microorganisms is expected. In this study, the superiority of MSE impeller by considering aeration condition and damage to them was revealed by shear stress at aerobic cultivation by aeration-agitation in yeast.
