Bioadsorption of Cu2+ and Ni2+ using Surface Display of Polyhistidine on Bacillus subtilis spore by use of the cotE anchor protein |
초록 |
We studied removing heavy metal using Bacillus subtilis spore surface display system. We used cot E protein as an anchoring motif because of its high abundance in coat layer and inserted double 6histidine tag at the C-terminal end of anchoring motif. We checked the surface expression of histidine tag using flow cytometry with FITC labelled anti-his6-antibody. Histogram of flow cytometry showed higher fluorescence intensity, possibly due to their outer location on Bacillus subtilis spore. We tried Cu2+ and Ni2+ adsorption with recombinant spore(CotE-His12) and DB104(wild type) used by atomic adsorption spectrometer. We confirmed that Cu2+ and Ni2+ adsorption capacity of CotE-His12 is higher than DB104(wild type). |
