A newly developed flat panel airlift photobioreactor with a defined circulation path was tested for microalgal culture. The bioreactor exposed the cells to intermittent light to improve the efficiency of light utilization through the flashing-light effect. During batch cultures in the new photobioreactor, the biomass productivity of Chlorella vulgaris was 1.7 times greater than in a randomly mixed bubble column of identical dimension. A reduction in light path from 30 to 15 mm increased the biomass productivity by 2.5-fold. A maximum dry biomass productivity of 0.11 g l(-1) h(-1) was obtained at an artificial illumination of 980 mu E m(-2) s(-1).
一种新开发的具有特定循环路径的平板气升式光生物反应器用于微藻培养测试。该生物反应器使细胞暴露于间歇光照下，通过闪光效应提高光利用效率。在新光生物反应器的分批培养过程中，普通小球藻的生物质生产力比相同尺寸的随机混合鼓泡塔高1.7倍。光程从30毫米减少到15毫米，生物质生产力提高了2.5倍。在980 μE m(-2) s(-1)的人工光照下，获得了0.11 g l(-1) h(-1)的最大干生物质生产力。
