| Abstract: | A new separation scheme was developed for recovery and isolation of biliproteins and polysaccharides from Spindina cultured in southern China. Isolation of biliproteins was accomplished with gel filtration on Sephacryl 200 and chromatography on hydroxylapatite. The isoelectric point, amino acid composition and spectrum of c-phycocyanin were determined respectively. A 130kd glycoprotein from Spirulina was purified by foam separation in a loop bubble column and gel chromatography on Sephadex G 200. The homogeneity of this glycoprotein was preven by SDS- PAGE. IR analysis of this glycoprotein showed the chical absorption of polysaccharide and indicated the existence of a-glycoside linkage. |
