摘要: Microalgal species Nannochloropsis limnetica, Botryococcus braunii, and Stichococcus bacillaris were compared for their ability to grow, remove CO2, accumulate lipids in biomass under CO2-enriched atmosphere. Overall, N. limnetica outperformed the other two cultures distinctly exhibited higher specific growth rate (0.999 d−1) CO2 fixation (0.129 gL−1 with a high lipid yield (40% w/w). The volumetric all three was validated productivity mass transfer methods (P<0.005 R2=0. 98). At 10% showed one-and-a-half times more carbon efficiency over B. S. bacillaris. On hand, total fatty acids of dispalyed an apparent increase oleic acid. Whereas, similar conditions, reduced eicosapentaenoic These findings suggest that at proved be efficient capture algal system can considered biofuel applications.
