Hot water-soluble polysaccharides from tetrasporic Pterocladia capillacea
Tetrasporic Pterocladia capillacea was sequentially extracted with water at room temperature, 50°, 70°and 90°. The polysaccharides obtained by extraction at 90°were fractionated by ion-exchange chromatography on DEAE Sephadex A-50 (Cl-), eluting with water and solutions of increasing sodium chloride...
