    • Påvisning av sekundærmetabolitter i marine bakterieisolater 

      Wedø, Charlotte (Master thesis; Mastergradsoppgave, 2011-06-14)
      Bioaktive forbindelser påvist hos marine invertebrater ses ofte å ha strukturelle likheter med bakterielle sekundærmetabolitter og antas derfor å være produsert av mikrobielle symbionter. Målet med oppgaven var å screene småskala kulturfiltrater fra marine bakterieisolater fra svamper og sjøpungen Synoicum pulmonaria for å identifisere mulige produsenter av sekundærmetabolitter ved sammenligning ...

    • Phototrophic, heterotrophic and mixotrophic growth in cold-adapted marine microalgae 

      Tovar Aguirre, Ana Lilia (Master thesis; Mastergradsoppgave, 2022-05-15)
      Microalgae are grown in different habitats and conditions, such as high salinity, extreme temperatures, and variable pH. Cold-adapted microalgae may have the capacity of generating high biomass production, which can potentially be produced under cold and light-limited conditions in the Arctic. Most microalgae are obligated photoautotrophs; however, few species have been found living in complete ...

    • Protein og kitin i grakse fra produksjon av Calanus® Oil 

      Udin, Therese Christina (Master thesis; Mastergradsoppgave, 2017-05-15)
      Letingen etter nye ressurser som er rik på flerumettede langkjedede omega-3 fettsyrer, har ført til utnyttelse av dyreplanktonet Calanus finmarchicus (raudåte). Det blir høstet inn ved tråling i overflaten under de mest lipidrike stadiene i vår- og sommermånedene. Den største andelen av lipidene er voksestere med et høyt innhold av omega-3 fettsyrer; stearidonsyre (18:4n-4), EPA (20:5n-3) og DHA ...

    • The Role of Silicate in the Parasitism of Pleurosigma sp. Diatoms by the Thraustochytrid Phycophthorum isakeiti 

      Powers, Daniel Jerome Finley (Master thesis; Mastergradsoppgave, 2020-05-15)
      The recently described thraustochytrid diatom parasite Phycophthorum isakeiti has been isolated from the marine system of northern Norway (Hassett, 2020). Protist P. isakeiti’s ecological role, biodiscovery potential, and interactions with a possible diatom host, Pleurosigma sp. remain largely unexplored. Here I present culturing experiments to test whether P. isakeiti is an obligate parasite. To ...

    • SAV Ag CpG/polyI:C formulated vaccination potentiate protective immune responses in Atlantic salmon - no additive or synergistic effect present when co-injecting a Rhabdovirus G-DNA vaccine 

      Thim, Hanna Leena (Master thesis; Mastergradsoppgave, 2013-02-11)
      Vaccines of today rely on adjuvant efficacy to provide a link between innate and adaptive immunity. CpG oligodeoxynucleotides (ODN) and polyinosinic:polycytidylic acid (polyI:C) are both toll-like receptor (TLR) ligands signaling through a combination of pathogen recognition receptors (PRR) and in mammals CpG/polyI:C are known to induce T-helper 1 (Th1) and cytotoxic T-lymphocyte (CTL) responses. ...

    • Securidine analogues from the marine bryozoan Securiflustra securifrons. 

      Salamonsen, Daniel (Master thesis; Mastergradsoppgave, 2021-05-12)
      Har isolert analoger av Securidine A, samt andre forbindelser fra arten Securiflustra securifrons, utført strukturoppklaring og testet for bioaktivitet.

    • Targeted gene editing of an infectious salmon anemia (ISA)-relevant gene in salmonids cells using the CRISPR/Cas9 Ribonucleoprotein complex 

      Strømsnes, Trygve André Hagen (Master thesis; Mastergradsoppgave, 2022-05-10)
      Background: The gene editing tool, CRISPR/Cas9, can potentially be applied in aquaculture to combat some of the problems of the farmed salmon industry including infectious diseases. The RNP (ribonucleoprotein)-based CRISPR/Cas9 strategy has recently been shown to be efficient in gene editing in diverse cell lines and organisms. Application of RNP strategy in salmon cell biology is still at its ...

    • Uptake of Polystyrene Nanoplastic and its Impacts on the Proteome of Salmonid cells 

      Heim, Oda (Master thesis; Mastergradsoppgave, 2023-06-27)
      Micro- and nanoplastic particles, produced from the breakdown of larger plastic debris, represent a whole new field of hazardous pollution with the potential to cause great damage on a range of marine species. This escalating concern of plastic pollution in marine environments and its consequential impacts on marine species, has emphasized the urgency for an in-depth understanding of the uptake and ...
