“…A total of five investigations were designed in this research. All the experiments were conducted at one factor a time, beginning with the introduction of different environmental factors such as incubator shaker agitation speeds (100, 130, and 160 rpm), light intensity (20, 27, and 34 µmol/m 2 /s), photoperiod (8,16, and 24 h) on the phototrophic cultivation of Amphora sp., followed by three main nutritional factors including glucose concentration (5,10,15,20, and 25 g/L), sucrose concentration (5, 10, 15, 20, and 25 g/L), and silicate concentration (50, 67, and 75 mg/L), the last on the heterotrophic cultivation of Amphora sp. Optimized variables would be brought forward to the subsequent experiments in all the above studies.…”

Eicosapentaenoic acid (EPA) could be extracted from diatoms such as Amphora sp. present abundantly in the ecosystems. In view of the key environmental and nutritional factors governing the diatoms growth rate, culture conditions were optimized for the biomass yield, total lipid content, EPA yield, and fatty acid composition under two main cultivation regimes: photoautotrophic and heterotrophic. The fastest growth rate about 0.20 ± 0.02 g/L and the highest EPA yield about 9.19 ± 3.56 mg EPA/g biomass were obtained by adding 10 g/L glucose and sucrose, respectively. Under photoautotrophic culture conditions, Amphora sp. rendered higher EPA yield at 100 rpm and 16:8 light/dark cycle. Total fatty acids produced predominantly comprised of an approximate 40–70% of saturated fatty acids, followed by 10–27% of monounsaturated fatty acids and then 8–25% of polyunsaturated fatty acids. These findings were able to pave a way for huge‐scale microalgal biomass production in commercial EPA production.
