“…The major fatty acids of the total lipids of N. zanardinii and C. indica were myristic acid, palmitic acid, oleic acid, C18, and C20 PUFA as in other brown seaweeds (Dawczynski et al 2007;Hofmann and Eichenberger 1997;Khotimchenko 1998;Kumari et al 2010;Li et al 2002;Sánchez-Machado et al 2004) (Tables 3 and 4). The fatty acid composition of SFA saturated fatty acids, MUFA monounsaturated fatty acids, PUFA polyunsaturated fatty acids seaweeds is sensitive to temperature (Khotimchenko 1998;Nomura et al 2013;Sewón et al 1997).…”

Seasonal variation of total lipid, fatty acids, fucoxanthin content, and antioxidant properties of two tropical brown algae (Nizamuddinia zanardinii and Cystoseira indica) from Iran

The present study investigates the seasonal changes in lipid components, fucoxanthin (Fx), and functional longchain n-3 (omega-3) polyunsaturated fatty acids (PUFAs) and also evaluates for their antioxidant activity of two tropical brown algae, Nizamuddinia zanardinii and Cystoseira indica, collected from the southeast coast of Iran. Results show a significant amount of fucoxanthin that is possibly due to the specific conditions of sampling area in terms of oxidative stress and the waves of southwest monsoon and thermal stress. Total lipid in October and November was higher compare to rest of the year. The percent of PUFA in N. zanardinii increased coinciding with a period of relative cold weather, but PUFA in C. indica increased in May when the weather is warm. However, in both species, seasonal variation in DPPH radical scavenging activity, CUPRAC, and total phenolic content did not show a particular pattern. A correlation between fucoxanthin content and DPPH radical scavenging activity was evident. Both algal species had higher phenolic content over the peak of maturity and fertility when the plant was tallest (October to December for both species and April for N. zanardinii). In general, variation of these factors in a tropical area such as Oman Sea is different from temperate regions. These changes in many cases are not as tangible, and further investigations are required to assess the variations.

“…They also vary in their FA compositions, exhibiting saturated fatty acids (SFAs), myristic and palmitic at sn -1 and C18 PUFAs, predominantly LA and ALA at sn -2 position while DGTS in marine algae are esterifi ed to long-chain PUFAs at both the sn -1 and sn -2 positions. DGTA contain palmitic, myristic, oleic, LA, ALA, AA and EPA as major FAs (Hofmann and Eichenberger, 1997;Makewicz et al , 1997). DGTA is considered to play an important role in the redistribution of acyl chains and the biosynthesis of galactolipids and DGTS in lipid-linked desaturation of fatty acids (Giroud and Eichenberger, 1989;Hofmann and Eichenberger, 1998).…”

“…Its level is highly plastic in algae and ranges between 1% and 97% (Dembitsky and Rozentsvet, 1996;Dembitsky et al , 1992;Fan et al , 2007;Hofmann and Eichenberger, 1997;Illijas et al , 2009;Kamenarska et al , 2004;Khotimchenko and Kulikova, 1999;Kulikova and Khotimchenko, 2000;Rozentsvet et al , 1995). Algal lipids are mostly characterized by saturated and monounsaturated fatty acids but many oleaginous algae exhibit the potential to accumulate long-chain PUFAs (AA, EPA and DHA).…”

“…In contrast, algal lineages such as the Phaeophyceae (Hofmann and Eichenberger 1997) produce both C 18 and C 20 PUFAs in significant amounts. A number of algae have become industrial sources of biotechnologically important PUFAs such as arachidonic acid (C20:4) or eicosapentaenoic acid (C20:5) (Colombo et al 2006, Spolaore et al 2006.…”

We report an oxidative burst triggered by prostaglandin A 2 (PGA 2 ) in the brown algal kelp Laminaria digitata, constituting the first such discovery in an alga and the second finding of an oxidative burst triggered by a prostaglandin in a living organism. The response is more powerful than the oxidative burst triggered by most other chemical elicitors in Laminaria. Also, it is dose-dependent and cannot be inhibited by diphenylene iodonium, suggesting that another source than NAD(P)H oxidase is operational in the production of reactive oxygen species. Despite the very strong oxidative response, rather few effects at other levels of signal transduction pathways could be identified. PGA 2 does not increase lipolysis (free fatty acids) in Laminaria, and only one oxylipin (15-hydroxyeicosatetraenoic acid; 15-HETE) was found to be upregulated in Laminaria. In a subsequent set of experiments in the genome model Ectocarpus siliculosus, none of 5 selected candidate genes, all established participants in various stress responses, showed any significant differences in their expression profiles.Key Words: Cyclopentenone; diphenylene iodonium; Phaeophyta; polyunsaturated fatty acids; prostaglandin A 2 INTRODUCTIONBrown algae (Phaeophyta) make up most of the benthic biomass on temperate and polar rocky shores. Kelp forests are key ecosystems of such coastal areas and they constitute habitat and breeding grounds for a very large diversity of marine life forms -besides offering a physical protection by providing a wave energy-absorbing buffer for coasts. Brown algae belong to a lineage that has been evolving independently of other major photosynthetic Received December 20, 2011, Accepted February 23, 2012 *Corresponding Author E-mail: fkuepper@abdn.ac.uk Tel: +44-1224+44- -274490, Fax: +44-1224 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. (Reymond and Farmer 1998, Orozco-Cárdenas et al. 2001).The oxidative burst was initially discovered in human macrophages (Baldridge and Gerard 1933). It is now recognized also as a key element of plant (Wojtaszek 1997, Mittler et al. 2004) and algal , Dring 2005, Cosse et al. 2007) defense, where it is considered both as a rapid defense response and an internal emergency signal. It consists of the rapid and massive production of ROS such as superoxide (O 2 -), hydrogen peroxide (H 2 O 2 ), and hydroxyl radicals (• OH)which are likely produced via the interaction of plasma membrane-associated NAD(P)H oxidases (Wojtaszek 1997). Hence, pathogen attack triggers both the production of ROS and the oxidation cascade of fatty acids leading to the production of bioactive oxylipins in plants. In algal systems, the oxidative burst was initially discovered in response to injury in a red alga (Collén et al. 1994). Over the last decade, oxidative...
