摘　　要：拟微绿球藻是一种含油量较高的藻种,适合作为生物柴油的原料.有研究发现,拟微绿球藻在稀土元素的胁迫下,油脂含量会增加.通过不同浓度铈处理拟微绿球藻,研究了铈对其光系统Ⅱ及抗氧化系统的影响.结果表明,不同浓度铈处理后,该藻的抗氧化物质活性均提高,PSⅡ反应中心荧光特性和能量分配都受到不同程度的影响.Nannochloropsis is a kind of algae with high oil content and is suitable as a raw material for biodiesel.Studies have found that oil content in Nannochloropsis increased under the stress of rare earth element.In this experiment,the effects of different cerium concentrations on algal photosystem II and antioxidant system were studied.The results showed that when Nannochloropsis were treated with cerium,the activities of antioxidants increased to different degrees,and the fluorescence parameters and energy distribution of PSII reaction center were also affected to varying degrees.
