Phycochemistry and pharmacological significance of filamentous cyanobacterium Spirulina sp

The cyanobacterium, Spirulina sp. is a photosynthetic blue-green alga with essential nutrients, vitamins nucleic acids, proteins, carbohydrates, fatty acids and pigments carotenes; and phycocyanins are the significant components having immunomodulatory, anti-inflammatory properties, which are used in food and cosmetics industries. Spirulina sp. can play an important role in human and animal nutrition for potential health benefits due to their phycochemical and pharmaceutical significance. This study highlights antibacterial, antifungal, antiviral, antioxidant, nephroprotective, cardioprotective, anticancer, neuroprotective, anti-aging, anti-inflammatory, and immunomodulatory properties. It highlights anti-anemic, antidiabetic, probiotic, anti-malarial, anti-obesity and weight loss, anti-genotoxicity, anti-thrombic, radioprotective, and detoxifying effects of Spirulina sp. Pharmaceutical studies indicate it may improve heart health and add to the treatment of diabetes, obesity and weight loss. It can play a major role in protecting the environment by recycling wastewater and providing food for humans and animals. Spirulina sp. can supply ingredients for aquaculture and agricultural feeds, pigments, antioxidants, and essential omega-3 oils, among other human health and wellness products. The amino acid of Spirulina is among the greatest qualititavely of any plant, even higher than that of soybean. Furthermore, cyanobacterium Spirulina sp. could be a future antimicrobial drug agent.
