A solution containing two proteins, Ovalbumin (OA) and Lysozyme (LZ), and an anionic surfactant, Sodium Dodecyle Sulfate (SDS), was adjusted to pH 6.0 which refered to an intermediate state between the isoelectric points of the proteins. The solution was processed by continuous foam separation. The results showed that a proper addition of SDS greatly improved the selective recovery of LZ to OA. The experimental data were well explained by a simple model that most of cationic protein molecules (LZ) are associated with SDS and the adsorption of all the species including LZ-SDS complexes are subjected to Langmuir adsorption isotherm. The results also showed that one of the Langmuir parameters, which means a kind of lyophillic property of adsorbed material, of LZ-SDS complexes was extremely large as compared with that of primary protein.ElsevierJournal Articleapplication/pdfhttp://hdl.handle.net/2115/13481https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/13481/1/Suzuki_etal_JCIS_2002.pdf0021-9797Journal of Colloid and Interface Science25324024082002-09-15enginfo:pmid/16290871info:doi/10.1006/jcis.2002.8526Copyright © 2002 Elsevierauthor
