Screening study reveals distinct biochemical and fatty acid profiles across 20 marine microalgae strains, highlighting potential applications in biofuels, food, and nutraceuticals.
20 marine microalgae strains from 8 genera were collected and screened for biomass generation and biochemical compositions including proteins, lipids, and carbohydrates.Fatty acid composition of extracted lipids was analyzed using GCMS to find out their uses in different industrial applications.Chlorella sp.shows the highest protein content of 52% among the 20 strains.Highest lipid content of 29% was observed in Dunaliella sp making it useful in the process of biofuel development.All the strains show presence of saturated fatty acids with monounsaturated fats (MUFA) are found only in 11 strains and polyunsaturated fats (PUFA) are found in 16 strains.Among PUFA ω-3 and ω-6 fatty acids are mostly abundant which have nutraceutical and cosmaceutical applications.Highest carbohydrate content of 70% was found in Pseudoneochloris marina which makes it valuable for food industries.
