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.

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.
