A split-column photobioreactor (SC-PBR), consisting of two bubble columns with different sizes, was developed to enhance the photon utilization efficiency in an astaxanthin production process from Haematococcus lacustris. Among the two columns, only the smaller column of SC-PBR was illuminated. Astaxanthin productivities and photon efficiencies of the SC-PBRs were compared with a standard bubble-column PBR (BC-PBR). Astaxanthin productivity of SC-PBR was improved by 28%, and the photon utilization efficiencies were 28-366% higher than the original BC-PBR. The results clearly show that the effective light regime of SC-PBR could enhance the production of astaxanthin.
开发了一种由两个不同尺寸的鼓泡塔组成的分柱式光生物反应器（SC-PBR），以提高红球藻虾青素生产过程中的光子利用效率。在这两个塔中，只有SC-PBR的较小塔被光照。将SC-PBR的虾青素生产力和光子效率与标准鼓泡塔光生物反应器（BC-PBR）进行了比较。SC-PBR的虾青素生产力提高了28%，光子利用效率比原来的BC-PBR高28%-366%。结果清楚地表明，SC-PBR的有效光照模式可以提高虾青素的产量。
