Fig. 5
Neutral lipid content and lipid productivity in P. tricornutum during the whole growth cycle. a, b Relative neutral lipid content analyzed by Nile red staining showed with histogram and line diagram, respectively. c, d Lipid content per 1 mg algae (histogram and line diagram, respectively). e, f Lipid content per 109 cells (histogram and line diagram, respectively). g, h Lipid content per liter culture (histogram and line diagram, respectively). Significant difference between WT and transgenic microalgae is indicated at *p < 0.05 or **p < 0.01 level. Each value represents mean ± SD (n = 3)
