  • Patent number: 5358858
    Abstract: A process for preparing phycoerythrin from Bangia atropurpurea or Porphyra angusta is disclosed. Spores of Bangia atropurpurea or Porphyra angusta, derived from their thalli, are cultivated under a controlled condition to germinate filaments. Phycoerythrin is then resulted from the extraction of filaments which are processed through drying powder-mill grinding, water or phosphate percolating and ammonium sulfate salting-out. The phycoerythrin is further purified by gel filtration. This process yields the phycoerythrin of 99% purity.
