“…The fatty acid profile in cyanophytes -high 16:0, 16:1n-7 cis, and 18:3n-3 content-was similar to that previously reported (Guedes et al, 2011;Lang et al, 2011;Scholz & Liebezeit, 2013). Fatty acid content differed between cyanophyte groups -the filamentous group had high α-linolenic acid content (13.4 to 37.5%), consistent with other studies (Zepka et al, 2007;Sharathchandra & Rajashekhar, 2011;Opris et al, 2013).…”

“…One fundamental aspect in nutrition of marine organisms is the proximate composition and quantity of polyunsaturated fatty acids (PUFAs) of microalgae (Xu et al, 2008;Guedes et al, 2011). Eicosapentaenoic acid (EPA: 20:5n-3) and docosahexaenoic acid (DHA: 22:6n-3), members of the PUFA family (n-3) are essential for marine organisms because they promote growth and high survival rates and are also components of membranes and storage organelles (Cardozo et al, 2007;Guedes et al, 2011).…”

“…The chlorophyte Tetraselmis suecica had a high level of palmitic acid (16:0), α-linolenic acid (ALA) (18:3n-3), and eicosapentaenoic acid (EPA) (20:5n-3), which are essential for nutrition of animals and humans (Brown, 2002;Patil et al, 2007;Guedes et al, 2011). In our study, the EPA content in Tetraselmis suecica was higher (13.8%) than that reported by Lourenço et al (2002) for Tetraselmis gracilis (10.7%) during early stationary growth phase, which makes it a good source of EPA.…”

ABSTRACT. The growth rate, fatty acid profile and toxicity of 21 microalgae strains (Cyanophyceae (3), Chlorodendrophyceae (1), Xanthophyceae (1) and Bacillariophyceae (16)), isolated from coastal waters of Baja California (NW México), were determined. Cyanophytes Komvophoron sp. had the highest growth rates (μ = 2.98 divisions day ). Fatty acid content differed according to taxonomic group. Diatoms contained the highest percentages of polyunsaturated fatty acids (n-3 and n-6 PUFAs), ranging from 23.4 to 60.7%, and eicosapentaenoic acid (EPA) was the most abundant. None of the residual media from the isolated microalgae strains were toxic to Artemia franciscana nauplii. We conclude that based on their growth rate, fatty acid profile, and lack of toxicity, all the isolated microalgae strains have the potential to be used alone or as part of a mixed diet for the culture of marine organisms.

“…Different clinical trials have been performed on EPA and the results warrant their effectiveness in relieving the inflammatory diseases, adjuvant therapy to cure schizophrenia or depression and also fortifying the effectiveness of chemotherapy agents 7 . In addition to DHA and EPA, which are classified as omega-3 fatty acids, some major fatty acids such as Alfa Linolenic Acid (ALA), Gamma Linolenic Acid (GLA) 8 , Arachidonic Acid (AA) 9 and Eicosatrienoic Acid (ETE), which play a great role in cellular membranes in different organisms and also offer various health effects for humans, have been reported from different microalgal strains 10,11 . Nowadays, DHA is obtained mainly from fish oil.…”

Background and Purpose: Nowadays, polyunsaturated fatty acids (PUFAs) are playing a great role in human wellbeing and health improvement. A wide spectrum of biological, medical and health benefit effects ranging from cardiovascular, neuronal, anticancer and antioxidant have been reported from different PUFAs in human. Methodology: In this study, six different species of microalgae belonging to the chlorophyta and cyanobacteria phylum were isolated from soil and water samples collected from Persian Gulf. Their growth rate, biomass and lipid production and productivity and more importantly their ability to produce PUFAs was investigated. Results: The isolated species represented a great fatty acid profile including many different polyunsaturated fatty acids (PUFAs) ranging from 6-20 carbon atoms. S. obliquus and N. muscorum proven to have a better profile for PUFAs production, whilst C. vulgaris could be considered as a more robust strain to produce other fatty acid classes. Besides, C. vulgaris with its higher growth rates (0.39 d-1)and S. obliquus owing to its higher total lipid content (43.92%) seems more interesting strains for scale up studies. Conclusion: The obtained results demonstrated the great potential of naturally isolated strains of microalgae for PUFA production and provided some insights in next studies to explore more producing strains.
