Abstract
AbstractMicroalgae are commonly cultivated using photobioreactors (PBRs). To investigate Chlorella vulgaris productivity, a 2.5‐L airlift photobioreactor (AL‐PBR) with vertical and incline baffles was newly developed using computational fluid dynamics (CFD), particle image velocimetry (PIV) methods, and dark/light cultures. A significant increase in cell density and lipid accumulation rate (LAR) in the AL‐PBR was observed. Hydrodynamic stresses including velocity fluctuation, pressure drop, looped bubble swarm, and vorticity magnitude were quantified in algae cultures, suggesting that microvortices induced light and CO2 distribution regulated the algae plastid metabolism in the exponential phase of growth. This study provides a fundamental practice to the scale‐up of bioreactors.
