EFEECTS OF RADIATION ON THE OPTICAL PROPERTIES OF SPIRULINA PLATENSIS AFTER REPLACING POTASSIUM IONS WITH CESIUM IONS IN NUTRITION MEDIUM

Abstract

The optical properties of Spirulina platensis were studied under varying ratios of cesium and potassium ions, followed by gamma radiation exposure. The study highlights the critical role of potassium ions in the post-irradiation recovery process of irradiated cells, regardless of the presence of cesium ions. Analysis of the obtained spectra revealed a high level of stability in the optical properties of Spirulina platensis under ionizing radiation, when not observed difference in terms of the constituents of spirulina. These results indicate the low chemical toxicity of cesium ions. Additionally, the paper explores a possible mechanism for the inhibition of the post-irradiation recovery process, suggesting that it may be due to the replacement of potassium ions by cesium ions—an essential factor for the growth and development of Spirulina platensis cell cultures.
