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