Effects of Tetracycline and Copper on Water Spinach Growth and Soil Bacterial Community

The effects of tetracycline (TC) and copper (Cu) on the growth water spinach bacterial community structure in soil were examined this study. results revealed that a single Cu treatment decreased development more severely than TC, toxic TC synergistic at low doses antagonistic high concentrations. had largest influence activities three antioxidant enzymes (Superoxide Dismutase (SOD), Peroxidase (POD), Catalase (CAT)) content Malondialdehyde (MDA) leaves, followed by composed treatment, with having least effect. 16Sr RNA sequence analysis showed richness diversity communities reduced either or treatment. greater effect composition microbial genus level TC. In conclusion, exhibited concentrations relevant indicators when concentration was fixed.
