Representation of (A) specific growth rate (d⁻¹), (B) average productivity (g L⁻¹ d⁻¹), (C) CO₂ biofixation rate (gCO₂ L⁻¹ d⁻¹), (D) oil content (%, w/w), (E) total chlorophyll content (μg/mg), (F) beta‐carotene content (mg/mg), (G) lutein content (mg/mg) from the cultures of Scenedesmus obliquus, Chlorella vulgaris, and Chlorella protothecoides (≈28°C; 74 μmol photons m⁻² s⁻¹; 1 vvm), subjected to the tested CO₂ concentrations: Air (2); 5% (v/v) CO₂ (2); 10% (v/v) CO₂ (2). Vertical bars represent SDs.
