Abstract

In the present study, bioceramic was prepared by impregnating surface layer protein (S-layer) isolated from extremophilic bacteria Bacillus licheniformis NARW 02 onto sol-gel-derived titanium phosphate (TiP) ceramic. The prepared bioceramic was used for adsorption of uranium ions from aqueous solution and compared with control lacking S-layer protein. The distribution coefficient value of TiP and bioceramic for uranium adsorption was 100.65 and 432.48 ml/g respectively. This study indicates that the bacterial S-layer can be potentially used to enhance the adsorption efficiency of the ceramics used in separation of uranium from waste water.
