摘      要：In this study,a fingerprint analysis method along with the EEM fluorescence spectra was used to characterize the SAPs released by Scenedesmus ***1 during the growth *** fractionation was used firstly to divide the SAPs into six resin fractions,and then size exclusion chromatography(SEC)was performed to separate each resin fraction into several subfractions with different molecular weights(MW).The fingerprint graph integrated the information revealed by resin fractionation as well as that by SEC,showing that main components of SAPs changed from the hydrophilic subfractions with MW of 10~2-10~3 Da to the hydrophobic subfractions with MW of 10~3-10~4 *** these results with the EEM fluorescence spectra of different resin fractions,the change of the main matters within SAPs could be inferred.
