Ag（I）、Ni（II）、Zn（II）离子对辐照螺旋藻的影响
Effect of Ag(I), Ni(II), Zn(II) ions on Irradiated Spirulina platensis
摘要：
采用紫外可见分光光度法研究了~（137）Cs γ射线和重金属离子Ni（II）、Zn（II）、Ag（I）对钝顶螺旋藻（Spirulinaplatensis）细胞的联合作用。结果表明，可能使用的γ射线与Ni（II）和Zn（II）离子一起不会改变这些金属离子对钝顶螺旋藻的相互作用的性质。而在相反的离子Ni（II）和Zn（II）的银离子，在辐照和非辐照状态下观察到的强度增加。电离辐射和其他应激源如银离子对钝顶螺旋藻的联合作用表现出协同效应，使C-藻蓝蛋白作为刺激剂提高其含量。
英文摘要：
Combined effects of 137Cs gamma irradiation and heavy metal ions Ni(II), Zn(II), Ag(I) on Spirulina platensis cells using UV-VIS spectrometry after three times irradiation and recultivation were discussed. It was shown, that possible use of gamma irradiation together with Ni(II) and Zn(II) ions does not change nature of interaction of these metal ions on Spirulina platensis. Whereas in contrast to the ions Ni (II) and Zn (II) for silver ions, an increase in intensity is observed in both the irradiated and non-irradiated states. The combined effects of ionizing radiation and other stressors such is silver ions for Spirulina platensis exhibit synergetic effects for C-phycocyanin as a stimulatory agent to raise the contents of it.
