Air-lift bioreactor is used in bioengineering, especially suitable for cell culture, microbial fermentation and the cultivation of photosynthetic organisms. This kind of reactor introduces air or other gases and uses the rising force of the gas to stir the culture medium, thereby achieving material mixing and gas exchange.

Low shear force, good gas exchange efficiency, easy operation, large-scale production.
The air lift fermenter is widely applied in modern biopharmaceutical processes thanks to its gentle mixing and efficient oxygen transfer. Key air lift fermenter uses include:
Cell culture & microbial fermentation: Supporting delicate mammalian cells, bacteria, and yeast for vaccines, enzymes, and proteins.
Photosynthetic organisms: Enhancing CO₂ distribution and light exposure in algae or cyanobacteria cultures.
Stem cells & regenerative medicine: Providing low-shear environments for safe expansion of stem cell populations.
Large-scale production: Cost-effective and scalable for monoclonal antibodies and other biological products.
