Solubilization of Radionuclide ²³⁸U and ¹³⁷Cs in Contaminated Soil with Acidithiobacillus thiooxidans

Abstract:

How to control and remediate the radionuclides-contaminated soil is attracting increasing attention. Researches on microbial solubilization of traces of ²³⁸U or ¹³⁷Cs in contaminated soil with Acidithiobacillus thiooxidans were conducted. The results show that ²³⁸U or ¹³⁷Cs can be solubilized by the strain, which can produce sulfuric acid steadily in liquid medium. In the 5th and 7th day the removal rate of ²³⁸U and ¹³⁷Cs were up to 78.71% and 81.48%, respectively. At the same time, the destroying of soil nutrients can be neglected
