摘要

研究了气升式光生物反应器在毛羽毛藻培养中的各种构型和模式。在受控的室内环境中分批培养内环和外环空运。由于更好的光照,外环系统比内环系统提供了更好的性能。在串联的内循环气升式光生物反应器中进行了连续操作。这样设计是为了尽量减少由于过度生长的细胞造成的光阻塞的影响,因为高密度培养在这种配置下,只局限于该系列的最后一个气举柱。在平板气升式光生物反应器中进行了室外大规模操作。由于光照不均匀,室外培养在生长速度上不如室内培养。在所调查的四种系统中,串联气升式光生物反应器连续培养的性能最好,细胞密度最高,为12.12 × 10个细胞mL。基于每平方米可安装的最大反应器数量的成本分析表明,室内系统每单位种植面积的运行成本最低,而室外系统由于继承了较大的生产率而提供了最高的利润。

Cultivation options for indoor and outdoor growth of Chaetoceros gracilis with airlift photobioreactors
Various configurations and modes of airlift photobioreactors were examined in the cultivation of Chaetoceros gracilis. Internal loop and external loop airlifts were cultivated in a batch mode in a controlled indoor environment. The external loop system provided a better performance than the internal loop system due to better light exposure. A continuous operation was conducted in an internal loop airlift photobioreactors-inseries. This was designed to minimise the effect of light blocking due to overgrown cells as the high-density culture was, in this configuration, only limited to the last airlift column in the series. Outdoor large-scale operation was conducted in a flat-panel airlift photobioreactor. Due to uneven light availability, the outdoor culture could not perform as well as the indoor one in terms of growth rate. Among the four systems investigated, the continuous culture in airlift photobioreactors-in-series provided the best performance with the highest cell density of 12.12 × 10 cells mL. Cost analysis based on the maximum number of reactors that can be installed in one square metre indicates that the indoor system requires lowest operating cost per unit cultivation area, whereas the outdoor system provides highest profit as a result of the inherited large productivity.
