Algae Research Supply: Algae Culture Porphyridium cruentum

The microalga Porphyridium sp. (Rhodophyta) 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.


  • Division: Rhodophyta (Red Algae)
  • Water Type: Seawater
  • Media: Use Algae Research Supply's Seawater Nutrient Media
  • Commonly used for: aquarium feed, aquaculture, study photosynthesis, research, science fair projects
  • This is one of the ONLY red microalgae. It is used by researchers to study the red protein based pigment phycoerythrine. Often used by the aquaculture community to bring RED color into filter feeders.
