摘要
铁对海洋浮游植物的生长起着重要的作用。在高营养盐低叶绿素(HNLC)海区,铁是藻类生长的限制因子;而在近岸,铁又是赤潮发生的激发因子之一。研究表明,可溶性铁对浮游植物生长有很强的控制作用,大部分可溶性铁是同具有极强铁亲和力的配位体螯合在一起的,如铁载体。因此,在对铁限制、铁加富实验的研究中,铁载体的提取与分析技术显得尤为重要。着重介绍了海洋浮游植物中铁载体的提取及检测分析技术。
Iron plays an important role in the growth of marine phytoplankton. In the high nutrient and low chlorophyll sea area, iron is a limiting factor of algal growth, and in the nearshore area, iron is one of factors to stimulate the occurrence of red tide. It is shown from study results that the soluble iron has a strong controlling effect on the phytoplanktonic growth, and most of soluble iron is chelated with ligand such as siderophore with high affinity to Fe 3+ . Therefore, the extraction and analysis technology of side- rophore is of great importance to the iron-limiting and iron-enrichment experiment and research. In this paper, the extraction, assay and analysis techniques of siderophore from marine phytoplankton are introduced in detail.
