Bioprospecting North Atlantic microalgae with fast growth and high polyunsaturated fatty acid (PUFA) content for microalgae-based technologies
Steinrücken, Pia; Erga, Svein Rune; Mjøs, Svein Are; Kleivdal, Hans Torstein; Prestegard, Siv Kristin (Peer reviewed; Journal article, 2017-09)Microalgae are considered to be an important and sustainable alternative to fish oil as a source for the polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Due to their health ... -
Comparing EPA production and fatty acid profiles of three Phaeodactylum tricornutum strains under western Norwegian climate conditions
Steinrücken, Pia; Prestegard, Siv Kristin; de Vree, Jeroen Hendrik; Storesund, Julia Endresen; Pree, Bernadette; Mjøs, Svein Are; Erga, Svein Rune (Peer reviewed; Journal article, 2018-03)Microalgae could provide a sustainable alternative to fish oil as a source for the omega-3 polyunsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, growing microalgae on a large-scale ... -
Enhancing EPA Content in an Arctic Diatom: A Factorial Design Study to Evaluate Interactive Effects of Growth Factors
Steinrücken, Pia; Mjøs, Svein Are; Prestegard, Siv Kristin; Erga, Svein Rune (Peer reviewed; Journal article, 2018-04-17)Microalgae with a high content of the omega-3 polyunsaturated fatty acids (PUFAs), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) are of great demand for microalgae-based technologies. An Arctic strain of the ... -
Marine Benthic Diatoms Contain Compounds Able to Induce Leukemia Cell Death and Modulate Blood Platelet Activity
Prestegard, Siv Kristin; Oftedal, Linn Silje Wathne; Coyne, Rosie Theresa; Nygård, Gyrid; Skjærven, Kaja Helvik; Knutsen, Gjert; Døskeland, Stein Ove; Herfindal, Lars (Peer reviewed; Journal article, 2009-11-18)In spite of the high abundance and species diversity of diatoms, only a few bioactive compounds from them have been described. The present study reveals a high number of mammalian cell death inducing substances in ... -
Specific metabolites in a Phaeodactylum tricornutum strain Isolated from Western Norwegian fjord water
Prestegard, Siv Kristin; Erga, Svein Rune; Steinrücken, Pia; Mjøs, Svein Are; Knutsen, Gjert; Rohloff, Jens (Peer reviewed; Journal article, 2016-12-30)We have searched for special characteristics in growth, protein expression, fatty acids and volatile organic compounds (VOCs) in a local Phaeodactylum tricornutum Bohlin strain (Bergen Marine Biobank), by comparing it with ...
