Abstract

The effect of copper (10, 25 and 50 μg/L) on the population growth, physiological state, and ultrastructure of the microalga Heterosigma akashiwo (Raphidophyceae) were studied. Copper had a greater effect on the mitochondrial membrane potential than on chlorophyll a fluorescence. The neutral lipid content was lower in the exposed cell than in control cells throughout the experiment. The morphology of organelles was not altered at any copper concentration; however, the number of vacuoles in the algal cells increased at 25 and 50 μg Cu/L.

摘要

研究了铜（10、25 和 50 μg/L）对微藻Heterosigma akashiwo（Raphidophyceae）种群生长、生理状态和超微结构的影响。铜对线粒体膜电位的影响大于对叶绿素a荧光的影响。在整个实验过程中，暴露细胞中的中性脂质含量低于对照细胞。在任何铜浓度下，细胞器的形态都没有改变；然而，藻细胞中的液泡数量在 25 和 50 μg Cu/L 时增加。
