摘要：
PHYSIOLOGICAL RESPONSES OF Euglena gracilis TO COPPER STRESS. The objective of this study was to evaluate the toxic effect of Cu2+ in the physiological development of E. gracilis. The results showed that E. gracilis had an effect on the dose-dependent growth to the concentration of metal. The exposure of E. gracilis metal at doses of 0.8 and 1.6 mM of Cu2+ showed a significant negative effect on the stability of DNA and photosynthetic pigments involved in capturing light in the antenna complex after 144 h of exposure to the metal.
