“…Pirian et al . (2020) also reported that the lipid content of eight macroalgae species, S. boveanum , S. trinodis , H. caroides , P. perforata , G. rugosa , C. racemosa , C. sertularioides and B. corticulans from the Persian Gulf was about 1.27–9.13%. Similar to our results, Gosch et al .…”

“…temperature, humidity, location and sampling period), water resource and the presence of nutrients can affect total lipid and fatty acid content in algal biomass (Pereira et al ., 2012; Abomohra et al ., 2018). Although seaweed distribution on the coastline of the Persian Gulf in the south of Iran and their nutritional compounds, such as proteins, carbohydrates, minerals, dietary fibres, vitamins and polyunsaturated fatty acids (PUFAs) (Rohani-Ghadikolaei et al ., 2012; Pirian et al ., 2017, 2020), have already been studied, macroalgal exploitation as a source of biodiesel has not yet been fully addressed, and biodiesel indices of seaweeds from the Persian Gulf have not been determined.…”

The aim of this work was to describe and compare the main fatty acids and biodiesel indices of some green and brown macroalgae (seaweeds) collected from the Persian Gulf, as an alternative raw material for renewable biodiesel production. The macroalgae showed low lipid content (< 10% DW) but marine macroalgae with total lipid content > 5% DW are a good source for biodiesel production. The total lipid content and saturated fatty acids (SFAs) of green algae were higher than that of brown algae, while higher accumulation of unsaturated fatty acids (USFAs) was observed in brown seaweeds. Further, the main fatty acid in all studied seaweeds was palmitic acid (C16:0), which was followed by oleic acid (C18:1). The results of this work showed that three of the green algae, especially C. sertularioides, could be a potential source of fatty acids for biodiesel production owing to their high total lipid content, high cold flow indices (long chain saturated factor, cold filter plugging point and cloud point) and a fatty acid profile rich in SFAs with a high amount of C18:1, which is suitable for oil-based bio products. In contrast, the brown seaweeds Sargassum boveanum and Sirophysalis trinodis lipid content had a high proportion of polyunsaturated fatty acids (PUFAs), which makes them suitable for replacing fish oil.

“…fasciata has been reported to produce a novel sphingosine derivative with antiviral activity (Parsaeimehr and Chen, 2013). Seaweeds exhibit a different type and level of fatty acids and many of which possess potential bioactivity (Pirian et al, 2017;Pirian et al, 2020). Several cytotoxic compounds such as fucoidans, laminarians, and terpenoids recognized by anticancer, antitumor and antiproliferative properties are reported to be abundant in seaweeds (Selim, 2012).…”

Applications of seaweeds as food ingredients and bioactive compounds are increasing these days. Many of seaweeds have to be evaluated for these purposes. This study investigated the biological activities of organic extracts of four green and a red macroalgae collected from the coast of Bandar Abbas, Iran. After species identification, the bioactivities of seaweeds have been studied by antioxidant assay (Ferric reducing power and total antioxidant capacity), total phenolic and flavonoid contents, antibacterial activity, and brine shrimp cytotoxicity activity on model organism, Artemia salina (Linnaeus, 1758) and Artemia franciscana (Kellogg, 1906) were anaysed. The results revealed the most effective algal extracts by maximum antioxidant capacity were recorded using methanol extracts of Ulva intestinalis Linnaeus 1753, and Ulva clathrata (Roth) C. Agardh 1811. In addition, the highest content of total phenolic content was recorded by green seaweeds. While, the highest flavonoid content was obtained from Gracilariopsis persica Bellorin, Sohrabipour & E.C. Oliveira. Most extracts showed significant antibacterial effects, with disk diffusion method. Among the various extracts, the n-hexane extract was found the highest zone of inhibition against analyzed pathogenic bacteria. U. intestinalis and U. clathrate have a better antimicrobial activity and are a potential source of antimicrobial compounds. Further, we found a best toxic effect to A. salina in n-hexane extract of G. persica, LC50 =125 μg/ml. Generally, the findings can be introduced the green seaweeds as priority species for biological properties and can be subject of isolation of the natural antimicrobials.

“…Similar to ascidians, seaweeds are considered an important source of n -3 long-chain PUFA, especially α-linolenic acid (ALA; 18:3 n -3) and EPA [ 4 , 44 ], with their potential as ingredients for aquafeed formulations also being increasingly acknowledged [ 45 ]. Although the lipid content in seaweed is relatively low (1.27% to 9.13%) [ 46 ], these organisms feature high n -3/ n -6 ratios, making them an appealing source of a valuable source of essential FA in health-promoting diets [ 47 ].…”

Screening for Health-Promoting Fatty Acids in Ascidians and Seaweeds Grown under the Influence of Fish Farming Activities

et al. 2021

The present study aimed to contrast the fatty acid (FA) profile of ascidians (Ascidiacea) and seaweeds (sea lettuce, Ulva spp. and bladderwrack, Fucus sp.) occurring in a coastal lagoon with versus without the influence of organic-rich effluents from fish farming activities. Our results revealed that ascidians and seaweeds from these contrasting environments displayed significant differences in their FA profiles. The n-3/n-6 ratio of Ascidiacea was lower under the influence of fish farming conditions, likely a consequence of the growing level of terrestrial-based ingredients rich on n-6 FA used in the formulation of aquafeeds. Unsurprisingly, these specimens also displayed significantly higher levels of 18:1(n-7+n-9) and 18:2n-6, as these combined accounted for more than 50% of the total pool of FAs present in formulated aquafeeds. The dissimilarities recorded in the FAs of seaweeds from these different environments were less marked (≈5%), with these being more pronounced in the FA classes of the brown seaweed Fucus sp. (namely PUFA). Overall, even under the influence of organic-rich effluents from fish farming activities, ascidians and seaweeds are a valuable source of health-promoting FAs, which confirms their potential for sustainable farming practices, such as integrated multi-trophic aquaculture.
