Porphyridium cruentum is a species of red alga in the family Porphyridiophyceae. The microalga Porphyridium sp. is a potential source for several products like fatty acids, lipids, cell-wall polysaccharides and pigments . The polysaccharides of this species are sulphated and their structure gives rise to some unique properties that could lead to a broad range of industrial and pharmaceutical applications. Additionally, P. cruentum biomass contains carbohydrates of up to 57% have been reported. Thus, the combined amount of carbohydrates in biomass and exopolysaccharides of this microalga could potentially provide the source for bio-fuel and pharmaceutical...
Recovery and purification of b-phycoerythrin produced by porphyridium cruentum using two-aqueous-phase systems and isoelectric precipitation
This invention focuses on a novel process in which Porphyridium cruentum biomass first undergoes a stage of cellular disruption and subsequently stages of recovery and purification in order to achieve the purified B-phycoerythin (BFE) protein dye, using isoelectric precipitation and two-aqueous-phase systems. The steps of recovery and purification include isoelectric precipitation followed by a step of liquid / liquid extraction by means of two-aqueous-phase systems that use polyethylene glycol (PEG) and phosphate salts. The BFE protein dye obtained in the two-aqueous-phase extraction step undergoes an ultrafiltration step in order to remove the polymer (PEG) and to obtain a dye with a purity greater than 4.0 defined as the relationship between the absorbencies at 545 and 280 nm (BFE purity=Abs 545 nm / Abs 280 nm).
