Mutant J61321 with enhanced siderophore production of Alteromonas aurantia AI8 was obtained after a series of chemical-physical mutageneses. It was found that the antibacterial activity against Vibrio anguillarum W-1 and siderophore production of the mutant were higher than those by the original strain A 18 which had been used in mariculture. The results of the specific assay（Csaky and Arnow methods） of siderophore showed that the sidrophore with hydroxamate group was produced by mutant J61321 and the original strain A 18, respectively, while the siderophore with catechol group was yielded by strain W-1 （Aibrio anguillarum）. Meanwhile, the siderophore yield, antibacterial activity and anti-chelator activity of strain J61321 were higher than those of its parent strain A 18.  相似文献

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。  相似文献
