Protein c-phycocyanin, structure, physicochemical and biological properties, methods of extraction

С-phycocyanin (phycocyanin) is a pigment-protein complex of the lightharvesting phycobiliprotein family that takes part in the primary phase of photosynthesis in lower plants. The phycocyanin content depends on such factors as the species of microalgae, physical state of biomass, extraction techniques, etc. The main methods for obtaining phycocyanin from biomass include chemical, physical and enzyme treatments with the following purification by such methods as precipitation with ammonium sulfate, ion exchange chromatography, and gel filtration chromatography. The commercial value of phycocyanin is directly related to the methods of its obtaining, purification and purity. The ratio of absorb…
