    • Climate Performance, Environmental Toxins and Nutrient Density of the Underutilized Norwegian Orange-Footed Sea Cucumber (Cucumaria frondosa) 

      Langdal, Andreas; Eilertsen, Karl-Erik; Kjellevold, Marian; Heimstad, Eldbjørg Sofie; Jensen, Ida-Johanne; Elvevoll, Edel O. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-26)
      Low trophic species are often mentioned as additional food sources to achieve broader and more sustainable utilisation of the ocean. The aim of this study was to map the food potential of Norwegian orange-footed sea cucumber (Cucumaria frondosa). C. frondosa contained 7% protein, 1% lipids with a high proportion of polyunsaturated fatty acids, and a variety of micronutrients. The nutrient density ...

    • Mass Cultivation of Microalgae: I. Experiences with Vertical Column Airlift Photobioreactors, Diatoms and CO2 Sequestration 

      Eilertsen, Hans Christian; Eriksen, Gunilla; Bergum, John-Steinar; Strømholt, Jo; Elvevoll, Edel O.; Eilertsen, Karl-Erik; Heimstad, Eldbjørg Sofie; Giæver, Ingeborg Hulda; Israelsen, Linn; Svenning, Jon Brage; Dalheim, Lars; Osvik, Renate Døving; Hansen, Espen Holst; Ingebrigtsen, Richard Andre; Aspen, Terje M; Wintervoll, Geir-Henning (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-17)
      From 2015 to 2021, we optimized mass cultivation of diatoms in our own developed vertical column airlift photobioreactors using natural and artificial light (LEDs). The project took place at the ferrosilicon producer Finnfjord AS in North Norway as a joint venture with UiT—The Arctic University of Norway. Small (0.1–6–14 m<sup>3</sup>) reactors were used for initial experiments and to produce inoculum ...
