英文摘要: The effects of different concentration Pb2+ (0. 1,1,10,50,100,200,400 mg/L) in BG11 on the growth, morphostructure and physiological characteristics of Chlorococcum sp. were studied. Compared with the cell cultured in BG11, the cell cultured in low concentrations ( <= 50 mg/L) showed few changes in pigment and thickness of cell wall; the cell wall of the cell cultured in high concentrations of Pb2+ ( >50 mg/L) became thicker, and the pigment decreased and the pyrenoid disappeared. When the concentrations of Pb2+ were 0.1 - 10 mg/L,the growth of Chlorococcum sp. showed no obvious difference compared with the control;when the concentration of Pb2+ was 50 mg/L, Chlorococcum sp. could maintain certain growth rate yet; however, when the concentration of Pb2+ was higher than 100 mg/L, the growth of Chlorococcum sp. was inhibited markedly. The contents of Chl a + Chl b or Chl a decreased gradually with the increase of the concenrations of Pb2+ in the medium. The photosynthesis of Chlorococcum sp. 2, 2, decreased gradually with the increase of Pb2+ Concentrations, when the concentration of Pb2+ was higher than 100 mg/L, the photosynthesis of Chlorococcum sp. could not be detected; when the concentration of Pb2+ was less than 50 mg/L,the respiration of Chlorococcum sp. increased gradually with the increase of Pb2+ concentrations, and when the concentration of Pb2+ was higher than 50 mg/L, they decreased gradually with the increase of Pb2+ concentrations. The content of malondiadehyde and activities of superoxide dismutase and peroxidase increased gradually with the increase of Pb2+ concentrations, and the activity of catalase increased at beginning and then decreased with the increase of Pb2+ concentrations. When the concentration of Pb2+ was <= 100 mg/L, the removal rate of Chlorococcum sp. on Pb2+ was > 95 %, and it was up 56.7% yet when the concentration of Pb2+ was 400 mg/L. The results demonstrated that the Chlorococcum sp. could be applied to the treatment of wastewater containing Pb2+, because the Chlorococcum sp. could endure the stress of Pb2+ and was of high removal rate on Pb2+.
