This work aim to partially eliminate the radioactive elements by using Saccharomyces cerevisiae grown in different carbon sources such as maltose, sucrose, starch, lactose, fructose and glucose, the analysis of the Phosphogypsum sample was compared after microbe treatment using different techniques for the variety of elements. It was obvious that Saccharomyces cerevisiae uptake the Uranium and Thorium and Radium contents by decreasing them (extraction) from the original mother sample with all different carbon sources. Many analytical techniques such as IR, XRF, chemical analysis, Geometric analysis, and scanning electron microscope were applied to monitor all the changes in the phosphogypsum samples, as well as the changes in radioactive elements content.
Key words: Radioactive elements, Biosorption, Saccharomyces cerevisiae, Phosphogypsum
