Abstract

Microalgae are single-celled microorganisms with different morphological, physiological, and genetic characteristics. They have an essential place in the aquatic ecosystem due to their photosynthetic feature. Microalgae produce various bioactive compounds as products of primary or secondary metabolism. The bioactive compounds they have; bioactive peptides, polyunsaturated fatty acids, bioactive polysaccharides, vitamins, phenolic compounds, and pigments. These components they produce can accumulate in the biomass and be released into the development environment. Thanks to the bioactive components they produce, microalgae have functional properties such as antioxidant, antimicrobial, antidiabetic, anticarcinogenic, and antihypertensive. Thanks to these features, it is reported that it has many uses and can acquire new areas of use day by day. Today, four microalgae species draw attention from the microalgae, which has a field of use in industries such as food, cosmetics, pharmaceutics, and aquaculture. These are Spiruna, Chlorella, Dunaliella and Haematococcus. Chlorella contains beta-1,3-glucan, which has antioxidant properties and acts as a free radical scavenger. Spirulina, on the other hand, can be used as a food supplement with its high amino acid content (62%). It is also a rich source of vitamins A, B1, B2, B12, and xanthophylls. Microags meet the essential fatty acids needs of fish with the polyunsaturated fatty acids they contain. Microalgae are the primary source of polyunsaturated fatty acids known as fish oil, such as eicosapentaenoic acid and docosahexaenoic acid. It has been reported that microalgae are an under-researched source in terms of both supplementary food and functional ingredient addition in the food industry for a healthy diet. The scope of this review, it is aimed to explain the bioactive compounds possessed by microalgae and the functional properties of these compounds.
