Most marine microalgae are typically cultivated in coastal areas due to challenges in inland cultivation. In this 185 days experiment, was semi-continuously cultivated inland using different photobioreactors (PBRs). The newly designed 700-liter (L) PBR exhibited tolerance to seasonal changes compared to the 150-L PBRs. The innovative in-situ oxygen release rate (ORR) measurement method results indicated that ORR was influenced by light intensity and temperature. The optimal temperature range for growth was 14–25 ℃, demonstrated cold tolerance and lipid accumulation at low temperatures. The maximum lipid content in 700-L and 150-L PBRs was 29 % and 28 %, respectively. Based on the average biomass productivity, the price of was $11.89 kg (or $3.35 kg based on maximum biomass productivity), which is cheaper than the current market price of $20.19 kg. From results, smaller PBRs at the same hydro electricity price are more cost-effective.

新型光生物反应器中海洋微拟球藻的低成本培养及其内陆室外条件下半连续培养的生产力趋势


由于内陆种植的挑战，大多数海洋微藻通常在沿海地区种植。在这个为期 185 天的实验中，使用不同的光生物反应器 (PBR) 在内陆进行半连续种植。与 150 L PBR 相比，新设计的 700 升 (L) PBR 表现出对季节变化的耐受性。创新的原位氧释放率（ORR）测量方法结果表明，ORR受光强度和温度的影响。最适生长温度范围为14-25℃，在低温下表现出耐寒性和脂质积累。 700 L 和 150 L PBR 中的最大脂质含量分别为 29% 和 28%。基于平均生物质生产率，价格为 11.89 千克（或基于最大生物质生产率为 3.35 千克），比当前 20.19 千克的市场价格便宜。从结果来看，相同水电价格下较小的PBR更具成本效益。
