摘　　要：用不同浓度纳米氧化铁(n Fe2O3)作用于聚球藻,并通过对聚球藻对数期的细胞数、叶绿素、总蛋白、总糖和中性脂含量等生理指标的测定,研究了n Fe2O3对聚球藻生理代谢的影响.结果表明,在0.3 mg/L至10 mg/L浓度范围内,n Fe2O3对聚球藻的生长未产生明显抑制或者胁迫的作用,表现为其细胞内的总蛋白、中性脂、总糖含量没有因n Fe2O3的存在而产生显著地变化.同时细胞数和叶绿素含量没有增加的趋势,说明在该浓度下铁元素的增加不会对聚球藻产生生长促进作用.The aim of this work is to study the effects of different concentrations of Fe2O3 nanoparticles on physiological metabolisms of Synechococcus by assessing their cell population,chlorophyll,total protein,total sugar,neutral lipid contents at exponential growth phase. The results demonstrates that the exposure of n Fe2O3 at 0. 3 mg / L to10 mg / L shows no significant inhibition or stress effects to algae growth. No remarkable change of protein,total sugar and neutral lipid contents is observed after exposure of n Fe2O3. No significant increase in cell population and chlorophyll content is observed neither,which means that n Fe2O3 has no promotive effect on algae growth.
