This study evaluates the combined effects of copper ions and light regimes on growth and metabolism of Chlorella vulgaris. Moderate Cu²⁺ concentrations (0.1–0.5 mg/L) stimulated biomass accumulation, while higher concentrations inhibited pigment synthesis. Red-blue LED lighting enhanced cell growth, whereas dimmed natural light promoted lipid accumulation.
