Effects of Different Iron Concentrations on the Growths of a Unicellular Strain and a Colonial Strain of Microcystis aeruginosa
不同铁浓度对单细胞和群体铜绿微囊藻生长的影响

We investigated the growth,photosynthetic efficiency,siderophore production and iron accumulation of two strains of M.aeruginosa,a unicellular strain M.aeruginosa PCC7806 and a colonial strain M.aeruginosa XW01,under iron-limited and iron-replete conditions.The identities of ITS and fur gene sequences of two strains were 95% and 98% respectively.That implied the two strains should be close relatives.Results showed the growths of two strains were severely inhibited under an iron-limited condition.The unicell...
