Exploring Porphyridium purpureum and Porphyridium aerugineum as alternative resources for phycobiliprotein production.

Microalgae not only fix carbon dioxide, but also represent a promising alternative resource for the production of proteins, lipids, and polysaccharides. This study employed two Porphyridium strains to compare their responses under different light qualities. P.

Phycobiliproteins from algae: Current updates in sustainable production and applications in food and health.

Phycobiliproteins are light-harvesting complexes found mainly in cyanobacteria and red algae, playing a key role in photosynthesis. They are extensively applied in food, cosmetics, and biomedical industry due to bright color, unique fluorescence characteristics and diverse physiological activities. They have received much attention in the past few decades because of their green and sustainable production, safe application, and functional diversity.
