چکیده انگلیسی
Removal of endocrine-disrupting chemical ethinylestradiol (EE2) from wastewater by microalgal mutant Chlorella PY-ZU1 under 15% CO2 were investigated. Moreover, the effects of EE2 on microscopic structure and antioxidation ability of microalgal cells were determined. EE2 concentrations in range of 0.01-5â¯mgâ¯Lâ1 stimulated microalgal growth. Increasing the original EE2 concentration from 0 to 5â¯mgâ¯Lâ1 increased the cell fractal dimension from 1.38 to 1.59 and reduced the cell size from 5.18 to 3.41â¯Î¼m. Meanwhile, superoxide dismutase and catalase activities, which represented cellular antioxidant capacity, first increased from 44.59 and 0.54â¯Uâ¯mLâ1 to peak values of 65.57 and 1.49â¯Uâ¯mLâ1, respectively, and then correspondingly decreased to 34.36 and 0.36â¯Uâ¯mLâ1. Malondialdehyde content that indicated the cell oxidation damage degree first decreased from 2.57 to 2.03â¯nmolâ¯mLâ1, then increased to 2.59â¯nmolâ¯mLâ1. The highest EE2 removal efficiency of 94% by Chlorella PY-ZU1 was achieved at the original EE2 concentration of 5â¯mgâ¯Lâ1.
