| SEQ. | Airlift bioreactor | mechanically agitated bioreactor |
| Mixing method | It contains an inner draft tube that creates the drafting force required for liquid circulation which can improve the bulk mixing. Meanwhile, oxygen transfer, internal circulation, and mixing are achieved by bubbling air. | It uses mechanical agitator to mix substance or broth. Meanwhile, oxygen transfer, internal circulation, and mixing are achieved by mechanical agitator |
| Benefit | It can reduce shear stress and heat generation by eliminating the mechanical agitator | Strong shear stress with higher heat generation by mechanical agitator |
