Porphyridium Cruentum Production

The marine microalga Porphyridium cruentum (P. cruentum) is known for its ability to synthesize a variety of high-value compounds, such as sulfated polysaccharides, pigments, polyunsaturated fatty acids (PUFAs), and phycobiliproteins. P. cruentum biomass can contain up to 40% polysaccharides. P. cruentum contains lipids and polyunsaturated fatty acids that provide health benefits by reducing the risk of cardiovascular disease, high cholesterol levels, inflammation, and cancer risk. Therefore P. cruentum may be used as a valuable ingredient in drug development. At the same time, the production ability of P. cruentum in the high-value compound shows great potential in cosmetic, nutraceutical, and industrial applications. CD BioSciences investigated the effects of temperature, residence period, light intensity, and salinity on the growth rate and overall light-to-energy conversion efficiency of P. cruentum grown on concentrated seawater and media-rich in urea, chelated iron, and other additives. The production process developed by CD BioSciences for P. cruentum can realize the cultivation level range from small-scale cultivation in the laboratory to large-scale cultivation in different types of bioreactors.
