| 摘 要： | 以普通小球藻(Chlorella vulgaris)为研究材料,研究了不同浓度的Hg2+和Cd2+对其生长的影响.结果表明:低浓度(00.50 mg/L)的Hg2+和Cd2+由于毒性兴奋效应能刺激普通小球藻细胞密度的增长,促进叶绿素含量的增加和蛋白质的合成;当Hg2+和Cd2+浓度进一步增加,则抑制普通小球藻的生长;当Hg2+和Cd2+的浓度分别为2 mg/L时,无蛋白积累.

| Abstract: | The effect of the concentration of Hg 2＋and Cd2＋on the growth of Chlorella vulgaris was studied.The results showed that low concentrations of Hg 2＋and Cd2＋（0 -0.50 mg/L） could stimulate the increase of cell density , increase chlorophyll and protein content because of the hormesis effect , while the growth of Chlorella vulgaris was inhibited by high concentrations of Hg2＋ and Cd2＋.When the concentration of Hg2＋ and Cd2＋ reached 2 mg/L, there was no protein accumulation in the algae cells . |
