Isolation of Bacteriorhodopsin from Halobacterium salinarium SP9

摘要

New efficient bacterirhodopsin (material for biochip) separation methods were studied. These new seapration methods take advantages of aqueous two phase interfacial condensation, ammonium sulfate precipitation and ultrafiltration. These new alternatives increased the yield of bacteriorhodopsin and enabled the large-scale bacteriorhopsin separation.
