Spirulina (Arthrospira): An Important Source of Nutritional and Medicinal Compounds

Abstract

Cyanobacteria are aquatic and photosynthetic organisms known for their rich pigments. They are extensively employed as food supplements due to their rich contents of proteins. While many species, such asAnabaenasp., produce hepatotoxins (e.g., microcystins and nodularins) and neurotoxins (such as anatoxin a),Spirulina (Arthrospira)displays anticancer and antimicrobial (antibacterial, antifungal, and antiviral) activities via the production of phycocyanin, phycocyanobilin, allophycocyanin, and other valuable products. This paper is an effort to collect these nutritional and medicinal applications ofArthrospirain an easily accessible essay from the vast literature on cyanobacteria.
