    • Adding zooplankton to the OSMAC toolkit: Effect of grazing stress on the metabolic profile and bioactivity of a diatom 

      Osvik, Renate Døving; Ingebrigtsen, Richard Andre; Norrbin, Fredrika; Andersen, Jeanette Hammer; Eilertsen, Hans Christian; Hansen, Espen Holst (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-03)
      “One strain many compounds” (OSMAC) based approaches have been widely used in the search for bioactive compounds. Introducing stress factors like nutrient limitation, UV-light or cocultivation with competing organisms has successfully been used in prokaryote cultivation. It is known that diatom physiology is affected by changed cultivation conditions such as temperature, nutrient concentration and ...
    • Bioactivity of a Marine Diatom (Porosira glacialis [Grunow] Jorgensen 1905) Cultivated With and Without Factory Smoke CO2 

      Osvik, Renate Døving; Andersen, Jeanette Hammer; Eilertsen, Hans Christian; Genevière, Anne-Marie; Hansen, Espen Holst (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-16)
      Using industrial emissions as a strategy for CO<sub>2</sub> sequestration through carbon capture and utilization (CCU) in cultivation of microalgae can potentially change cultivation factors such as pH, nutrient availability and presence of trace metals, which could alter the growth and metabolism of the microalgae. It is therefore important to investigate whether such changes in culturing conditions ...
    • 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 ...
