Assessment of the biodegradability of xanthan in offshore injection water
(Master thesis, 2015-04-29)The application of biopolymers in EOR operations is considered environmental friendly compared to synthetic polymers. However, microbial degradation of the biopolymers may lead to a deterioration of effect in EOR applications. ... -
Assessment of the carbon monoxide metabolism of the hyperthermophilic sulfate-reducing archaeon Archaeoglobus fulgidus VC-16 by comparative transcriptome analyses
(Peer reviewed; Journal article, 2015)The hyperthermophilic, sulfate-reducing archaeon, Archaeoglobus fulgidus, utilizes CO as an energy source and it is resistant to the toxic effects of high CO concentrations. Herein, transcription profiles were obtained ... -
Associated bacteria of Botryococcus braunii (Chlorophyta)
(Peer reviewed; Journal article, 2019-03-27)Botryococcus braunii (Chlorophyta) is a green microalga known for producing hydrocarbons and exopolysaccharides (EPS). Improving the biomass productivity of B. braunii and hence, the productivity of the hydrocarbons and ... -
Asynchronous Accumulation of Organic Carbon and Nitrogen in the Atlantic Gateway to the Arctic Ocean
(Peer reviewed; Journal article, 2018-11-15)Nitrogen (N) is the main limiting nutrient for biological production in the Arctic Ocean. While dissolved inorganic N (DIN) is well studied, the substantial pool of N bound in organic matter (OM) and its bioavailability ... -
At what cost? Attempting to quantify cost of resistance in bacterium-phage interactions
(Doctoral thesis, 2023-12-15)Biodiversiteten i mikrobielle samfunn er svært stor. Organismene som danner samfunnet må stadig gjøre avveininger mellom ulike karaktertrekk som påvirker deres muligheter for vekst, konkurranse og overlevelse. For å beskrive ... -
Atlantic bluefin tuna spawn early to avoid metabolic meltdown in larvae
(Journal article; Peer reviewed, 2022)To predict shifts in phenology and distribution of organisms we need to understand how survival through early life stages depends on environmental conditions. Here, we present a mechanistic model of development, feeding ... -
Atlantic halibut reovirus (AHRV): Reservoirs and transmission in culture systems.
(Master thesis, 2015-11-27)The ability to expand within the aquaculture industry is essentially based on reliable production of healthy juvenile fish. In 2013 a new aquareovirus was found to be associated with high juvenile mortality at a Norwegian ... -
Atlantic salmon (Salmo salar L.) post-smolts challenged two or nine weeks after seawater-transfer show differences in their susceptibility to salmonid alphavirus subtype 3 (SAV3)
(Peer reviewed; Journal article, 2016-04-11)Background Pancreas disease (PD), caused by salmonid alphavirus (SAV), is an important disease affecting salmonid aquaculture. It has been speculated that Atlantic salmon post-smolts are more prone to infections in the ... -
Atlantic salmon (Salmo salar L.) sterol metabolism and metabolic health – impact of dietary lipids
(Doctoral thesis, 2014-12-12)Marine resources are today limited, and due to this there is an increasing inclusion of non-marine lipids in the diet of farmed salmonids. An optimal diet for farmed Atlantic salmon (Salmo salar L.) should not only promote ... -
Atlantic salmon and sea trout display synchronised smolt migration relative to linked environmental cues
(Journal article; Peer reviewed, 2020)Anadromous salmon and sea trout smolts face challenging migrations from freshwater to the marine environment characterised by high mortality. Therefore, the timing of smolt migration is likely to be critical for survival. ... -
Atlantic salmon male post-smolt maturation can be reduced by using a 3-hour scotophase when inducing smoltification
(Journal article; Peer reviewed, 2023)Photoperiod regulates the occurrence of unwanted male post-smolt maturation during the production of large (>100 g) Atlantic salmon (Salmo salar) smolts. However, the optimal daylength for triggering smoltification, but ... -
Atlantic salmon populations reveal adaptive divergence of immune related genes - a duplicated genome under selection
(Peer reviewed; Journal article, 2016-08-11)Background: Populations of Atlantic salmon display highly significant genetic differences with unresolved molecular basis. These differences may result from separate postglacial colonization patterns, diversifying natural ... -
Atlantic salmon post-smolts adapted for a longer time to seawater develop an effective humoral and cellular immune response against Salmonid alphavirus
(Peer reviewed; Journal article, 2018-11)Salmonid alphavirus (SAV) causes pancreas disease (PD) in Atlantic salmon (Salmo salar L.) and disease outbreaks are mainly detected after seawater transfer. The influence of the smoltification process on the immune ... -
Atlantic salmon Salmo salar and ballan wrasse Labrus bergylta display different susceptibility to clonal strains of Paramoeba perurans
(Journal article; Peer reviewed, 2020)Amoebic gill disease (AGD), caused by the marine amoeba Paramoeba perurans, is an important disease of farmed Atlantic salmon Salmo salar L. in Norway. The use of wrasse as cleaner fish in salmon net pens raises questions ... -
Atmospheric deposition effects on plankton communities in the Eastern Mediterranean: A mesocosm experimental approach
(Peer reviewed; Journal article, 2017-07-04)The effects of atmospheric deposition on plankton community structure were examined during a mesocosm experiment using water from the Cretan Sea (Eastern Mediterranean), an area with a high frequency of atmospheric aerosol ... -
Attuning to a changing ocean
(Journal article; Peer reviewed, 2020)The ocean is a lifeline for human existence, but current practices risk severely undermining ocean sustainability. Present and future social−ecological challenges necessitate the maintenance and development of knowledge ... -
