The present work aims to evaluate performance of a novel zigzag-flow column photobioreactor (ZZ-flow PBR) designed to achieve a high biomass during A. platensis cultivation. The ZZ-flow PBR was installed with four optimized zigzag baffle structures mounted over its outer (riser) section. The optimum parameters (w = 18 and h= 5 cm) for each zigzag baffle structure generated zigzag flow patterns throughout microalgae solution, which decreased mixing time (MT) by 51.1% but increased mass transfer coefficient (MTC) by 58.2% as compared with traditional PBR. The solution followed zigzag path along the baffles to facilitate frequent movement of microalgae cells across the PBR, where overall photochemical efficiency φPSII and Fv/Fm increased by 21.4% and 12.4%, respectively. The intracellular photosynthesis promoted electron transfer rate (ETR) by16.6% and chlorophyll a content by 8.3%, resulting in an increased biomass yield and CO₂ fixation by 28.8% and 36.3%, respectively, relative to conventional column PBR.

目前的工作旨在评估一种新型锯齿流柱光生物反应器 (ZZ-flow PBR) 的性能，该反应器旨在在A. platensis期间实现高生物量栽培。ZZ-flow PBR 安装有四个优化的锯齿形挡板结构，安装在其外部（立管）部分上。每个锯齿形挡板结构的最佳参数（w = 18 和 h = 5 cm）在整个微藻溶液中产生锯齿形流动模式，与微藻溶液相比，混合时间 (MT) 减少了 51.1%，但传质系数 (MTC) 增加了 58.2%传统的 PBR。该溶液沿着挡板沿着锯齿形路径移动，以促进微藻细胞在 PBR 上的频繁移动，其中整体光化学效率 φPSII 和 Fv/Fm 分别提高了 21.4% 和 12.4%。细胞内光合作用使电子转移率（ETR）提高了16.6%，叶绿素a含量提高了8.3%，从而提高了生物量产量和CO ₂与传统色谱柱 PBR 相比，固色率分别提高了 28.8% 和 36.3%。
