چکیده انگلیسی
In this study, Nannochloropsis oceanica CY2 was grown in deep-sea water (DSW)-based medium in 5-L plastic bag-type photobioreactors (PBRs) for the autotrophic production of Eicosapentaenoic acid (EPA, 20:5n-3). EPA production of N. oceanica CY2 was stimulated when it was grown in 100% DSW amended with 1.5â¯gâ¯Lâ1 NaNO3, achieving a EPA content of 3.1% and a biomass concentration of 3.3â¯gâ¯Lâ1. An outdoor-simulated microalgae cultivation system was also conducted to validate the feasibility of outdoor cultivation of the CY2 strain in plastic bag-type PBRs. Using an inoculum size of 0.6â¯g/L, the biomass concentration in the PBR culture was 3.5â¯gâ¯Lâ1, while the EPA content and productivity reached a maximal level of 4.12% and 7.49â¯mgâ¯Lâ1â¯dâ1, respectively. When the PBRs were operated on semi-batch mode, the EPA productivity could further increase to 9.9â¯mgâ¯Lâ1â¯dâ1 with a stable EPA content of 4.1%.
