摘要

对micans原心菌(proocentrum micans E.)在亚致死剂量镉环境下生长的研究表明，该鞭毛藻对浓度为5微克/升的污染物具有高度敏感性。用脉冲极谱法测定了过滤后培养基对镉的吸收。固定后可以看到活细胞中不明显的结构变化。micocentrum micans对镉的高敏感性和易于培养的特点使其成为一种适宜的镉污染指标。

[Action of cadmium on a free dinoflagellate Prorocentrum micans E: growth, cadmium absorption and cell modifications].

The study of the growth of Prorocentrum micans E. submitted to sublethal doses of cadmium demonstrated a high sensitivity of this Dinoflagellate to the polluant starting with concentration of 5 microgram/l. The uptake of cadmium was measured by pulse polarographic analysis of the filtered culture medium. Structural modifications, not apparent in living cells, are visible after fixation. The high sensitivity of Prorocentrum micans to cadmium, also its easy culture, makes it a suitable pollution indicator of this heavy metal.
