Effects of P concentrations on C. regularis intracellular components. Lipid, protein, and starch content (a), and lipid productivity (b) on day 4. NlimP5.4, NlimP25, NlimP45, NlimP150, and NlimP250 represent the protocols using the modified BG11 media with P concentrations of 5.4, 45, 150, and 250 mg L−1, respectively. Error bars were obtained based on triplicate measurements
