제목 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).
