Abstract

The nutritional and therapeutic potential of the
filamentous cyanobacterium Spirulina (Arthrospira platensis) is remarkable, being rich in proteins,
vitamins, and essential fatty acids, and is also recognized for its antioxidant properties. Spirulina’s easy growth adaptability positions it as a top sustainable food source, especially in geographic regions with agricultural challenges. The current study emphasizes the significance of optimizing cultivation methods, focusing on a modified Zarrouk medium to enhance growth conditions. Key findings show that spirulina exhibited a high protein content of 69.74%, along with elevated levels of polyunsaturated and monounsaturated fatty acids, underscoring spirulina’s role in addressing malnutrition and supporting metabolic health. Furthermore, the study highlights the need for in-depth research on spirulina’s bioactive compounds to fully harness its benefits in the nutraceutical industry and promote innovative formulations in food and pharmaceuticals.
