Effect of Ag(I), Ni(II), Zn(II) ions on Irradiated Spirulina platensis

TL;DR

This study investigates how gamma irradiation combined with Ni(II), Zn(II), and Ag(I) ions affects Spirulina platensis, revealing that silver ions uniquely increase C-phycocyanin content through synergistic effects.

Contribution

It demonstrates the combined effects of gamma irradiation and heavy metal ions on Spirulina, highlighting silver ions' distinct stimulatory impact on C-phycocyanin production.

Findings

Gamma irradiation with Ni(II) and Zn(II) does not alter metal interactions.

Silver ions increase in intensity in irradiated and non-irradiated states.

Synergistic effects enhance C-phycocyanin content with silver ions.

Abstract

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.
