Uranium sequestration abilities of Bacillus bacterium isolated from an alkaline mining region.

The present study elaborates uranium sequestration by bacteria from alkaline wastewaters. In the investigation, a few bacterial strains were isolated from alkaline uranium mine water and were tested for uranium sequestration properties 16S rRNA analysis assigned the 10 bacterial isolates to 4 genera of Actinobacteria and Firmicutes. Among all the isolates tested, the strain Bacillus aryabhattai (TP03) has shown superior sequestration capacity at 5 and 10 mg/L U in 1 mM carbonate-bicarbonate buffer at pH 9.
