ABSTRACT

The effects of copper nanoparticles (Cu-Np) on the microalga Synechococcus elongatus BDU10144 were investigated. The results showed that Cu-Np treatment decreased the chlorophyll a content, phycobiliproteins, and total protein concentration in the microalga. In addition, Cu-Np treatment increased the lipid peroxidation and glutathione-S-transferase activity, and decreased the superoxide dismutase and catalase activity. These results suggest that Cu-Np treatment induced oxidative stress in the microalga, which could lead to cell damage and death.The findings of this study provide valuable insights into the potential toxicity of Cu-Np on microalgae and contribute to our understanding of the environmental implications of nanoparticle exposure. Keywords: copper nanoparticles (Cu-Np), Synechococcus elongata, oxidative stress, chlorophyll a, phycobiliproteins, total protein, lipid peroxidation, glutathione-S-transferase, superoxide dismutase, catalase
