“…In the same regard, those species with a high proportion of MUFAs (C18:1) and low PUFAs content are preferable feedstock because this proportion improves the quality of the biofuel (Knothe 2008). In this study, wild and cultured R. pseudopalmata showed higher SFAs/UFAs ratios (4.3-10.9) than those reported for Mediterranean species (0.8-4) recently proposed as potential feedstock for biofuels (El Maghraby & Fakhry 2015). Therefore, in terms of SFAs and PUFAs requirements for biofuel production R. pseudopalmata shows promising potential.…”

SUMMARY Rhodymenia pseudopalmata is a red alga that grows at the Caribbean coast of the Yucatan Peninsula and has been proven successful in cultivation. In this study we present the lipid composition of R. pseudopalmata collected from wild populations during three different seasons of 2013. Cultured material was also analyzed and compared in order to evaluate its value as feedstock for biotechnological uses. Thin layer chromatography, 1 H and 13 C NMR spectroscopy and gas chromatography‐mass spectrometry were used to assess variations in their lipid composition. Our results showed that the dominant lipid classes were phospholipids both in wild and cultured materials. The phospholipids phosphatidylcholine and phosphatidylglycerol and the glycolipid monogalactosyldiacylglycerol were present in both wild and cultured R. pseudopalmata, whereas the phospholipid lysophosphatidylcholine was only found in wild material. Fatty acids (FAs) showed a high monounsaturated FAs (MUFAs) content with oleic acid (C18:1ω9) as the dominant compound (78 and 94% of the MUFAs for wild and culture materials, respectively). Saturated FAs (SFAs) represented approximately 90% of the total fatty acid content, with palmitic acid (C16:0) reaching approximately 83% of the SFA content. Rhodymenia pseudopalmata was low in polyunsaturated FAs when compared to other red algae. Other compounds such as 1‐heptadecene, 1‐hexadecene, 15‐heptadecenal, 3‐eicosene 6,10,14‐trimethyl‐2‐pentadecanone, phytol, and heptadecane were also found. Lipid composition differences between the wild and cultured algae suggest that light and nutrients can be manipulated to modify lipid composition. Based on its lipid composition and cultivation feasibility, R. pseudopalmata could be a potential source for nutraceuticals and biofuels production.

“…For example, TL seems to decrease while depth increases (Ito and Tsuchiya, 1977), which could be linked to light intensity since Hotimchenko (2002) has shown that TL content increases when light intensity decreases. Briefly, it seems that minimum TL content is observed in summer while maximum TL content is observed in autumn and winter (Honya et al, 1994;Nomura et al, 2013) or in winter and spring (El Maghraby and Fakhry, 2015;Nelson et al, 2002).

“…Though the lipid fraction has been less studied and typically does not surpass 5% of the dry seaweed matter in green seaweeds (El Maghraby & Fakhry, ; Kendel et al., ; Maehre, Malde, Eilertsen, & Elvevoll, ), it may comprise molecules with valuable bioactivities and may be a tool in differentiating seaweeds themselves and products derived from seaweeds, thereby enhancing traceability and reliability. Indeed, lipid profiling—such as overall and per lipid class fatty acid profiles—may be helpful in the assignment of algal taxonomic position and yield signature profiles for application in organic geochemistry and food studies (Rajasulochana, Krishnamoorthy, & Dhamotharan, ).…”

The lipid composition of five species of green seaweeds (Chaetomorpha linum, Rhizoclonium riparium, Ulva intestinalis, Ulva lactuca, and Ulva prolifera) grown in fish pond aquaculture systems was studied. In particular, the overall fatty acid (FA) profile and the FA profile of each main lipid class found in these seaweed species were thoroughly analyzed. It was found that every seaweed had a specific FA profile, whose specificities were rendered more obvious with the study of the FA profile per lipid class. However, between U. lactuca and U. intestinalis, there were only minor differences. Nonetheless, it was possible to identify significant differences between the palmitic acid content in the phospholipid (PL) and glycolipid (GL) classes of each seaweed. A clear distinction between the FA profiles of R. riparium and C. linum, which belong to the Cladophorales order, and those of Ulva genus, Ulvales order, was also determined. Moreover, there were also differences among lipid classes, yielding large contrasts between PLs + GLs and triacylglycerols (TAGs) as well as between monoacylglycerols (MAGs) and free fatty acids (FFAs). This study also found evidence supporting the location of particular FAs in specific TAG positions. FA profiles have the potential to be used as a chemotaxonomic tool in green seaweeds, providing a simple method to check authenticity of seaweed used as food.
