Abstract:
Objective To study the physiochemical properties of selenium exopolysaccharide from Porphyridium sp.(Se-PSP).Methods The Se-PSP was obtained from ASW,a sort of culture medium added with some selenious acid solution,and was purified by DEAE-52 cellulose column and identified by Sephadex G-200.The acidity,UV spectral absorption,paper chromatography,and gelose electrophoresis of Se-PSP solution were studied.Results and Conclusion Proper concentration of selenious acid in ASW culture had no influences upon the growth of Porphyridium.Se-PSP prepared in this way didn't contain protein and nucleic acid and the solution of Se-PSP showed acidity.It is probable that Se-PSP contain two fractions of PSP.
