Leaching experiments were carried out using the Deino-ure, a genetically engineered bacterium of Deinococcus radiodurans, to investigate its impact on the migration patterns of uranium in soil. In comparison to Deino-wt and control group, the Deino-ure exhibited a decrease in leached uranium (VI) content, an increase in total soil uranium content, yielding a uranium retention rate of 60.98%. The equilibrium enrichment capacity was 53 mg/g, which was consistent with the pseudo-first-order reaction kinetic model (correlation coefficient R2 = 0.99792). This validates the impact of Deino-ure on the forms of uranium in soil, demonstrating a transformation of the free state uranium into less migratory forms. The products of uranium enrichment were mainly the hydrated calcium uranyl oxide minerals. [ABSTRACT FROM AUTHOR] |
