As a necessary micronutrient for algal growth, iron (Fe) has important effects on the physiological metabolism and enzymatic reactions of algae. In this study, a series of experiments were designed to compare the effects of different kinds of iron on the growth of . Results showed that the promotion of iron species on algae growth was in order of ferric ammonium citrate > EDTA-Fe > iron ions > iron oxalate. When the concentration of iron is in the range of 0.1-0.8 mg/L, iron species have more significant influences on Anabaena bloom compared with iron concentration. Our experiments also revealed that has the strongest adsorption capacity for iron ion among the four iron sources and further induced. This leads to the toxicity of the iron ion group to algal cells at low concentration.
作为藻类生长必需的微量营养素，铁（Fe）对藻类的生理代谢和酶促反应具有重要影响。在本研究中，设计了一系列实验来比较不同种类的铁对[藻类名称未给出]生长的影响。结果表明，铁物种对藻类生长的促进作用顺序为柠檬酸铁铵＞乙二胺四乙酸铁＞铁离子＞草酸铁。当铁浓度在0.1 - 0.8 mg/L范围内时，与铁浓度相比，铁物种对鱼腥藻水华的影响更为显著。我们的实验还表明，[吸附物质未给出]在四种铁源中对铁离子具有最强的吸附能力，并进一步诱导[相关结果未明确]。这导致低浓度下铁离子组对藻类细胞具有毒性。
