“…Seaweeds are known as a low-energy, low-caloric food, and an explanation for this is the low content in lipids. Besides that, in recent years, interest in the lipid composition of marine algae has raised considerably because a big part of seaweed lipid content is constituted by ω-3 and ω-6 PUFAs, specifically α-linolenic (18:3ω-3), octadecatetraenoic (18:4ω-3), arachidonic (20:4ω-6), and eicosapentaenoic (20:5ω-3) acids [27][28][29]. Indeed, algae are essentially the only organisms able to produce long-chain PUFAs, ranging from 14 to 24 carbons, due to the presence of specific enzymes responsible for desaturation processes [29,30].…”

The red seaweed group (Rhodophyta) is one of the phyla of macroalgae, among the groups Phaeophyceae and Chlorophyta, brown and green seaweeds, respectively. Nowadays, all groups of macroalgae are getting the attention of the scientific community due to the bioactive substances they produce. Several macroalgae products have exceptional properties with nutraceutical, pharmacological, and biomedical interest. The main compounds studied are the fatty acids, pigments, phenols, and polysaccharides. Polysaccharides are the most exploited molecules, which are already widely used in various industries and are, presently, entering into more advanced applications from the therapeutic point of view. The focuses of this review are the red seaweeds’ compounds, its proprieties, and its uses. Moreover, this work discusses new possible applications of the compounds of the red seaweeds.

“…Despite the low macroalgal lipid content but it is characterized by a high content of polyunsaturated fatty acid PUFA, especially the arachidonic, eicosapentaenoic, α-linoleic, and octadecatetraenoic acids which had the prohibition of cardiovascular infections, diabetes, antimicrobial antiviral and antioxidant abilities [ 39 ]. The antioxidant activities of the extracted fatty acids from Pterocladia capillacea and Osmundaria obtusiloba were more than 50% Ascorbic Acid Activity (AsA) [ 40 ]. Bioactive peptides from red seaweed Polysiphonia urceolata and Palmaria palmata are known as antioxidant agents [ 35 ].…”

Red Seaweed “Rhodophyta” are an important group of macroalgae that include approximately 7000 species. They are a rich source of structurally diverse bioactive constituents, including protein, sulfated polysaccharides, pigments, polyunsaturated fatty acids, vitamins, minerals, and phenolic compounds with nutritional, medical, and industrial importance. Polysaccharides are the main components in the cell wall of red algae and represent about 40–50% of the dry weight, which are extensively utilized in industry and pharmaceutical compounds, due to their thickening and gelling properties. The hydrocolloids galactans carrageenans and agars are the main red seaweed cell wall polysaccharides, which had broad-spectrum therapeutic characters. Generally, the chemical contents of seaweed are different according to the algal species, growth stage, environment, and external conditions, e.g., the temperature of the water, light intensity, nutrient concentrations in the ecosystem. Economically, they can be recommended as a substitute source for natural ingredients that contribute to a broad range of bioactivities like cancer therapy, anti-inflammatory agents, and acetylcholinesterase inhibitory. This review touches on the main points of the pharmaceutical applications of red seaweed, as well as the exploitation of their specific compounds and secondary metabolites with vital roles.

“…Acutodesmus obliquus CN01 that was isolated from Malaysia was shown to well adapt to the temperature in Malaysia, which can reduce the upscale cost if to be used for production purposes. Apart from ALA, palmitic acid which is another main component of the fatty acid profile in these three microalgae has an outstanding antioxidant activity 44 and has been identified as antitumor agent 45 .

The main purpose of this study is to provide information on the biochemical composition of the total lipid extract of three different native freshwater microalgae namely Acutodesmus obliquus CN01, Chlorella sp. Carolina-15-2069, and Chlorella vulgaris NIES-1269 at different growth phases, cultured under standardized conditions that will be useful for commercialization purposes due to the content of α-linolenic acid (ALA), a type of omega-3 fatty acids. We monitored growth, biomass accumulation, chlorophyll content, lipid content and fatty acids composition in all three freshwater microalgae. In addition, this study seeks to throw some light on the lipid content of a newly isolated freshwater green alga Acutodesmus obliquus CN01 which have shown to give significant quantities of ALA, an added nutritional value to this microalga oil. Acutodesmus obliquus CN01 exhibited the fastest growth rate among the three microalgae used. Biomass was shown to be enhanced in the nitrogen enrichment medium. The outcomes from this study indicated that newly isolated Acutodesmus obliquus CN01 from Malaysia cultured under normal condition showed fast growth rate with high lipid content and also high ALA content. Therefore, from this study, Acutodesmus obliquus CN01 was identified as species of choice to be further explored for its potential to produce omega-3 fatty acids.
