Abstract
The green alga Scenedesmus obliquus was incubated with heavy metals (Cd2+, Zn2+, Mn2+, Ni2+) with and without selenium. S. obliquus exhibited higher rates of growth and some metabolic activities in cultures containing 0.1 mmol/L Se than those only containing the heavy metals. The positive effect of Se was found with all metals but was negligible with Mn2+.
摘要
将绿藻斜生栅藻与重金属（镉离子、锌离子、锰离子、镍离子）一起培养，培养条件分为添加和不添加硒两种情况。与仅含有重金属的培养物相比，斜生栅藻在含有0.1毫摩尔/升硒的培养物中表现出更高的生长速率和一些代谢活性。发现硒对所有金属都有积极作用，但对锰离子的作用可忽略不计。
