Abstract: The major engineering factors impacting on photosynthetic conversion efficiency (PCE) are analyzed, and the recent progress in PCE promotion with respect to engineering approaches is reviewed. The key issues to improve the PCE are improving the time and space distribution of light and regulating the fluid dynamic behavior in the photobioreactor (PBR). The practical approaches include the accommodation of the incident light energy, artificial importation of light into the PBR, optimization of geometry and structure of the PBR, design of internals in the PBR and optimization of the air flux and aeration zone in the PBR. For the further improvement of PCE, the light time-space distribution and fluid dynamic behavior should be optimized simultaneously in the PBR, and the development of PBR and optimization of culture process should be integrated in the further studies.

Key words: microalgae cultivation, photosynthetic conversion efficiency, photobioreactor, process optimization
