| 摘 要： | 微藻固碳是一种新型节能减排技术，具有长期可持续发展的潜力。本文对两株富油微藻（球等鞭金藻和微拟球藻）进行了富碳培养下生长特性及中性脂积累特性的研究。两株富油微藻的最佳培养条件为10%CO2浓度和f培养基。本研究对两株富油微藻的最大生物量产率、总脂含量、最大油脂产率、微藻的C含量和CO2固定率进行了测定。球等鞭金藻的各参数指标分别为：142.42±4.58g/（m2·d），39.95%±0.77%，84.47±1.56g/（m2·d），45.98%±1.75%和33.74±1.65g/（m2·d）。微拟球藻的各参数指标分别为：149.92±1.80g/（m2·d），37.91%±0.58%，89.90±1.98g/（m2·d），46.88%±2.01%和34.08±1.32g/（m2·d）。实验结果显示，两株海洋微藻均属于高固碳优良藻株，适合应用于微藻烟气减排技术开发，具备用于海洋生物质能耦合CO2减排开发的潜力。

| Abstract: | Biological CO2 sequestration by microalgae is a promising and environmentally friendly technology applied to sequester CO2. The characteristics of neutral lipid accumulation by two marine oil-rich microalgal strains, namely, Isochrysis galbana and Nannochloropsis sp., through CO2 enrichment cultivation were investigated in this study. The optimum culture conditions of the two microalgal strains are 10% CO2 and f medium. The maximum biomass productivity, total lipid content, maximum lipid productivity, carbon content, and CO2 fixation ability of the two microalgal strains were obtained. The corresponding parameters of the two strains were as follows: ((142.42±4.58) g/(m2·d), (149.92±1.80) g/(m2·d)), ((39.95±0.77)%, (37.91±0.58)%), ((84.47±1.56) g/(m2·d), (89.90±1.98) g/(m2·d)), ((45.98±1.75)%, (46.88±2.01)%), and ((33.74±1.65) g/(m2·d), (34.08±1.32) g/(m2·d)). Results indicated that the two marine microalgal strains with high CO2 fixation ability are potential strains for marine biodiesel development coupled with CO2 emission reduction. |
