The biosorption of strontium ions by immobilization, unimmobilized yeast (Saccharomyces cerevisiae) cells with calcium alginate and blank calcium alginate beads were studied in this research. The results showed that the beads of sodium alginate had certain ability of absorption of strontium ions; the biosorption of strontium ions by unimmobilized yeast cells was more stable, but the rate was slow at low concentrations; the biosorption by immobilized yeast was best, the biosorption may reach 80% at low strontium ions concentrations (10 mg/L). The biosorption rates of immobilized and unimmobilized yeast cells reached the same degree at the end. The Freundlich model was better than Langmuir model to describe the equilibrium isotherm. The pseudo-second-level model was fit to analysis the biosorption kinetics. The results indicated that calcium alginate can be used as the good immobilization vector for yeast cells and the immobilized and unimmobilized yeast cells showed better biosorption capacity at low strontium ions concentration under culture condtions.

“…In the study of nutrient fluxes in plants, the suitability of using radioactive contaminants as tracers is a complex question, which has guided several researches [1][2][3][4][5]. For being chemically similar to some available nutrients in soil (such as potassium or ammonium), radiocaesium is absorbed by plant roots, being transported to its various compartments.…”

“…Uptake of radionuclides from contaminated soil represents a significant pathway of human radiation exposure, either due to the direct consumption of cereals, fruits and vegetables or, indirectly, following consumption of milk and meat from animals fed on contaminated vegetable matter [8]. The understanding the radioactive mineral uptake by crop plants and the knowledge of its distribution in different organs is important in the agricultural management, to avoid its possible negative health effects.…”

Current knowledge on the basic radionuclide tolerance indicates that plants may develop mechanisms preventing the damaging effects of radionuclide stress. The radionuclides content was determined in the Mediterranean coastal black sand soil and in the edible portions of the four food crop plant species, viz., Eruca sativa, Lycopersicon esculentum, Pasidium guajava and Mangifera indica. Biochemical and nutritional constituents were assessed to elucidate the possible effect of radionuclides on the edible portions of the plants. The ability of the four study plant species to accumulate Uranium and Thorium in their edible portions from the coastal black sand soil is higher than that absorbed from the inland agricultural soils. The nutritional constituents were affected by the high concentrations of Uranium and Thorium in the plant tissues. The total protein, moisture content, total phenolic compounds, total chlorophyll, total carotenoids, β-Carotene and Lycopene were positively correlated with Uranium and Thorium concentrations in the plant tissues, while the mineral content, vitamin C and total flavonoids were suppressed by high concentrations of Uranium and Thorium in the plant tissues. The fluctuations in the biochemical or nutritional constituents of the plant edible portions are considered an important defense mechanism to control the redox state of the cells accumulating radionuclides with high levels.
