Description
Strong-reducing gene (dsrA) and the fluorine-resistant gene (flr-2) were cloned into D. radiodurans to prepare a recombinant Deino-dsrA-flr-2 strains. Then, the influencing factors of uranium enrichment by Deino-dsrA-flr-2 and its enrichment mechanism were studied. When the initial concentration of uranium was 30 mg/L, the pH was 5, the biomass was 0.016 g and the enrichment time was 75 min, the Deino-dsrA-flr-2 had the best remove effeciency of U(VI). SEM and TEM could clearly observe uranium deposits on the surface of bacteria; EDS also indicated that uranium appeared on the surface of Deino-dsrA-flr-2. Compared with D. radiodurans, Deino-dsrA-flr-2 can better remove uranium. (author)
