TLDR
This is the first report on the fatty acid profiles of Nannochloropsis oceanica, ChroococcusSp.Abstract:
Twelve algal strains representing the classes Cyanophyceae, Prymnesiophyceae, Bacillariophyceae, Rhodophyceae, Cryptophyceae, Chlorophyceae, Xantophyceae and Eustigmatophyceae were selected mainly from the culture collection of the Norwegian Institute for Water Research (NIVA). The algae were grown as continuous cultures in a 1.8 l. reactor, internally illuminated with an 11 W fluorescent tube. The retention time was adjusted in the range 2–4 days to fit the growth rate of the algae. The growth responses and fatty acid composition were analysed. The maximum production rate was obtained with Pseudokirchneriella subcapitata (0.63 g 1−1 day−1) and the lowest with Porphyridium cruentum 0.13 g 1−1 day−1. Arachidonic acid (AA) and eicosapentaenoic acid (EPA) were the dominating polyunsaturated fatty acids (PUFAs) in P. cruentum, while only EPA accumulated in Phaeodactylum tricornutum. Docosahexaenoic acid (DHA) was the major PUFA in Isochrysis galbana, while Pavlova sp. had both EPA and DHA. This is the first report on the fatty acid profiles of Nannochloropsis oceanica, Chroococcus sp., Synechococcus sp. and Tribonema sp.read more

Lipid productivity as a key characteristic for choosing algal species for biodiesel production
TL;DR: The importance of lipid productivity as a selection parameter over lipid content and growth rate individually is demonstrated and provides a framework for decision-making and a starting point for further investigation of species selection.
Journal ArticleDOI
Commercialization potential of microalgae for biofuels production
TL;DR: A critical evaluation of the available information suggests that the economic viability of the process in terms of minimizing the operational and maintenance cost along with maximization of oil-rich microalgae production is the key factor, for successful commercialization ofmicroalgae-based fuels.

A rapid method of total lipid extraction and purification.
E. G. Bligh,W. J. Dyer +1 more
TL;DR: The lipid decomposition studies in frozen fish have led to the development of a simple and rapid method for the extraction and purification of lipids from biological materials that has been applied to fish muscle and may easily be adapted to use with other tissues.

Essential fatty acids in health and chronic disease
TL;DR: Alpha-linolenic acid, found in green leafy vegetables, flaxseed, rapeseed, and walnuts, desaturates and elongates in the human body to EPA and DHA and by itself may have beneficial effects in health and in the control of chronic diseases.

Health benefits of docosahexaenoic acid (DHA)
Lloyd A. Horrocks,Young K. Yeo +1 more
TL;DR: The association of DHA deficiency with depression is the reason for the robust positive correlation between depression and myocardial infarction, and patients with cardiovascular disease or Type II diabetes are often advised to adopt a low-fat diet with a high proportion of carbohydrate.
