“…For PI, 16:0 and 13:1 acids were typical in D. membranacea as well as in F. vesiculosus and A. nodosum (Jones and Harwood 1992). In TAG, 14:0, 16:0 and 18:1 acids accounted for 83% of total fatty acids demonstrating the predominance of medium-chain fatty acids in this unpolar lipid in which the fatty acid composition has been reported to undergo seasonal variations in F. serratus (Kim et al 1996). The role of the different polar lipids, especially that of DGTA, in the metabolism of D. membranacea is the subject of further investigations.…”

“…membranacea contained significant amounts of TAG accounting for 20 mol% of the total lipids. This value might vary according to the physiological conditions, since in field-grown F. serratus, seasonal variations of the TAG content were observed (Kim et al 1996).…”

“…Since ARA and OTA have the same number of double bonds, and ARA is more to xic than EPA, the degree of unsaturation does not seem to be a key determinant of toxicity level (Parrish 2013).EPA with 2% and DHA with 3% were the t wo PUFA mainly detected in April, 2012. Fatty acid co mposition of algal lipids varies widely with species, habitat, light, salinity, pollution and environmental conditions (Kim et al, 1996;Ratana-Arporn and Chirapart, 2006) and in most studies 16:0 is predominant (Khotimchenko et al, 2002;Li et al, 2002;Gressler et al, 2010;Leblond et al, 2003). Dinoflagellates are the major contributors to the marine food web and are second only to diato ms as primer producers of organic matter in the Ocean (Tappan, 1980).…”

Noctiluca scintillans reached the highest abundance (5105 ind/m 3 ) in April; and April was an important period in the Black Sea ecosystem because of the seasonal thermocline. While the relationship between temperature and abundance was important (P<0.05, r 2 =-0.8), the relationship was not important between salinity and abundance (P<0.05, r 2 =-0.06); and Chlorophyll-a (Chl-a) and abundance (P<0.05, r 2 =-0.2). It was determined that total lipid was 0.5% in wet weight (WW). It was shown that the main Saturated Fatty Acids (SFA) were 16:0 (24%) and 18:0 (6%), main M onounsaturated Fatty Acids (MUFA) were 18:1ω-9c (22%) and 16:1ω-7 (4%), main Polyunsaturated Fatty Acids (PUFA) were 18:2ω-6c (19%) and 20:4ω-6c (8%). Phytosterols were the most important sterols in N. scintillans; and stigmasterol was 60 µg/gr and β-sterol was 8µg/gr as the most important ones in phytosterols. α-tocopherol was the highest amount (10.8 µg/g) in lipophilic vitamins. It was found that M alondialdehyde (M DA) was 65 µg/g, total protein was 10 mg/g, Glutathione (GSH) was 10565 µg/g and GSSG) was 49 µg/g. Consequently, PUFA and α-tocopherol were the most important biochemical parameters and α-tocopherol may reduce toxicity in blooms of N. scintillans because of inhibitory effect of α-tocopherol on lipid oxidation. Additionally, we can say that N. scintillans is a resistant dinoflagellate against oxidative stress.

“…A current source of commercial AA is the fungus Mortierella alpina, in which the AA content can be as high as 7.7 g/L culture (Zhu et al, 2006). Several algal species that contain AA have also been examined, including the red microalga Porphyridium cruentum (Ahern et al, 1983), some diatoms (Dunstan et al, 1994), the green microalga Tetraselmis suecica (Servel et al, 1994), and the brown seaweed Fucus (Kim et al, 1996).…”

The non-utilized biomass of the aquacultured seaweed Undaria pinnatifida, particularly the rhizoid, is an alternative source of arachidonic acid (AA). Of the five aquacultured kelps that were tested, U. pinnatifida yielded the highest amount of AA, which was isolated from the rhizoids. Its identity (C20:4 n-6) was confirmed from gas chromatography-mass spectrometry spectral data. The optimal conditions for post-harvest storage or pretreatment of the rhizoids in Provasoli's enriched seawater for AA extraction were determined to be pH 7.8, 2% CO 2 -enriched air, 20 μmol m -2 s -1 light, and 10°C. Under these conditions, the AA content after 1 day of storage was enhanced by up to 127%. In the absence of light under ambient aeration, the AA content after 1 day of storage diminished to 90%. Rhizoids collected late in the season (April and May) contained the highest amounts of AA (approximately 2.5 mg/g tissue).
