原始语种摘要: Abstract(#br)Isochrysis sp. is a marine microalga and is a potential source of eicosapentaenoic acid and docosahexaenoic acid, which possess several health benefits. In general, Isochrysis sp. grow well in nitrate-rich culture medium which influences fatty acid biosynthesis; therefore, this study focused on how nitrate influences cellular metabolism in the marine microalga Isochrysis sp. CASA CC 101. Initially, response surface methodology was performed to optimize the level of major nutrients: nitrate and phosphate. The results showed that Isochrysis sp. when grown with nitrate at a concentration of 593 mg.L −1 produced higher eicosapentaenoic acid (7.3 mg.L 1 ), whereas Isochrysis sp. when grown with higher concentration of phosphate did not produce higher levels of eicosapentaenoic...
