Effect of copper oxide nanoparticle on growth, protein content, chlorophylls and carotenoid in (Chlorella vulgaris)

Copper oxide nanoparticles are widely used in industrial production, are released in the environment and can induce toxicity to aquatic organisms. In this study, effects of copper oxide nanoparticles on growth, total protein content, chlorophylls and carotene of Chlorella vulgaris in various concentrations (control, 0/01, 1. 10 and 100 mg/l) were investigated for six days. The results showed that the number of algae cells and total protein significantly decreased with increasing concentrations of copper oxide nanoparticles (P
