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 sulfated 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.[1] This alga contains phycoerythrin that can be extracted by lyse and chromatography.[2]
