Porphyridium cruentum
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
The genus Porphyridium has been classified among blue-green, red, and green algae.
