| This study explores the cultivation of Spirulina using desalination brine waste as a growth medium, offering a sustainable method to produce high-protein biomass. Spirulina, a filamentous blue-green alga, is rich in protein and essential nutrients, making it an ideal alternative to traditional protein sources. In this research, desalination brine waste was used, and its salt concentration was optimized to create a conducive environment for Spirulina cultivation. The algae were grown under controlled light and temperature conditions, yielding 2.5 grams of dried biomass per 2 liters with a protein content of approximately 60%, along with significant amounts of carbohydrates and essential minerals like potassium, calcium, and sodium. Structural analysis confirmed the healthy growth of Spirulina filaments, and elemental analysis indicated a rich nutritional profile. These results suggest that Spirulina cultivation using desalination waste is not only feasible but also presents a highly nutritious, economically viable, and sustainable alternative protein source, particularly for athletes and health-conscious consumers. Moreover, this method provides an innovative approach to recycling desalination waste, contributing to more sustainable aquaculture and food production systems. | ||
