- •
Gas velocity in airlift reactor affects mixing, light distribution and CO2 supply.
- •
At sufficient CO2 supply, light is limiting to algal growth and productivity.
- •
Positron Emission Particle Tracking shows cell trajectory and light history in ALR.
- •
Below critical minimum gas velocity, slow circulation leads to light limited growth.
- •
Gas velocity optimised for CO2 and light supply, improves energy efficiency in ALR.
