A novel cyclic flow photobioreactor, designed for the capture and recycle of CO using microalgae, was deployed at a coal-fired power plant. Scenedesmus acutus was cultured continuously for a four-month period, during which a biomass productivity of 0.1-0.2 g L day was observed. Samples taken for DNA sequencing showed a strong correlation between the composition of the culture and environmental conditions. Dry and liquid biomass samples and the industrial fertilizers used for preparation of the nutrient medium were analyzed to determine the presence of heavy metals (As, Cd, Hg, Se) and results were compared with standardized and/or regulated maximum contaminant levels (MCLs) for metals in several possible algae derived products. Concentrations of the metals in dry algae biomass were consistent with the incorporation of metals from the supplied nutrients.
一种新型的循环流动光生物反应器，旨在利用微藻捕获和回收 CO，已在燃煤电厂投入使用。连续培养 Scenedesmus acutus 四个月，期间观察到生物量生产力为 0.1-0.2 g L day。用于 DNA 测序的样品显示，培养物的组成与环境条件之间存在很强的相关性。对干燥和液体生物量样品以及用于制备营养培养基的工业肥料进行了分析，以确定重金属（As、Cd、Hg、Se）的存在，并将结果与几种可能的藻类衍生产品中金属的标准和/或规定的最大污染物水平（MCL）进行了比较。干燥藻类生物质中的金属浓度与从供应的养分中吸收金属的情况一致。
