| Abstract： | Utilizing flue gas CO2 2 to co-produce eicosapentaenoic acid (EPA) with microalgae is considered an ideal approach for combating climate change and reducing cultivation costs. However, microalgal species that can efficiently produce EPA under high-CO2 2 conditions are scarce. This study identified that the eustigmatophycean strain Vacuoliviride crystalliferum demonstrates rapid growth under 20 % CO2 2 conditions (0.22 vvm), achieving a biomass concentration and productivity of 3.90 g/L and 229.26 mg/L/d, respectively. The EPA content and EPA productivity were found to be 4.28 % (w/w) and 9.80 mg/L/d, respectively. Additionally, an improved biomass concentration of 3.39 g/L and EPA content and productivity of 4.32 % (w/w) and 11.28 mg/L/d were obtained in a 30 L up-scaled cultivation system. Taken together, these findings suggest that V . crystalliferum is a promising candidate for integrating flue gas sequestration with EPA production. |
