Microbial colonization and community stability in a marine post-smolt RAS inoculated with a commercial starter culture
(Journal article; Peer reviewed, 2021)The performance of a commercial starter culture was investigated in a new marine post-smolt RAS, analyzing the microbial communities of 100 samples collected monthly over a year from biofilter biofilm carriers, tank wall ... -
Microbial communities and processes in ice-covered Arctic waters of the northwestern Fram Strait (75 to 80° N) during the vernal pre-bloom phase
(Peer reviewed; Journal article, 2011-09-20)Marine microbial communities have been little studied in Arctic waters, especially during the winter–spring transition before the development of extensive phytoplankton blooms. This study investigated microbial plankton ... -
Microbial Communities in a Flow-Through Fish Farm for Lumpfish (Cyclopterus lumpus L.) During Healthy Rearing Conditions
(Peer reviewed; Journal article, 2019-07-12)Lumpfish can efficiently remove sea lice from Atlantic salmon in net-pens, and production of lumpfish in closed fish farms is a new, fast developing industry in Norway. However, periodic outbreaks of bacterial diseases in ... -
Microbial Diversity of Terrestrial Geothermal Springs in Armenia and Nagorno-Karabakh: A Review
(Journal article; Peer reviewed, 2021)The microbial diversity of high-altitude geothermal springs has been recently assessed to explore their biotechnological potential. However, little is known regarding the microbiota of similar ecosystems located on the ... -
Microbial dynamics in high latitude ecosystems. Responses to mixing, runoff and seasonal variation a rapidly changing environment
(Doctoral thesis, 2017-11-08)The pronounced warming at high latitude alters a range of physical conditions i.e. the magnitude of runoff, sea-ice extent and strength of stratification and thus affect the biological systems. As microorganisms form the ... -
Microbial inventory of deeply buried oceanic crust from a young ridge flank
(Peer reviewed; Journal article, 2016-05-27)The deep marine biosphere has over the past decades been exposed as an immense habitat for microorganisms with wide-reaching implications for our understanding of life on Earth. Recent advances in knowledge concerning this ... -
Microbial iron reduction and greenhouse gas production in response to organic matter amendment and temperature increase of periglacial sediments, Bolterdalen, Svalbard
(Journal article; Peer reviewed, 2022)Arctic permafrost soils store substantial reserves of organic matter (OM) from which microbial transformation contributes significantly to greenhouse gas emissions of CH4 and CO2. However, many younger sediments exposed ... -
Microbial Nitrogen Cycling in the Marine Deep Biosphere
(Doctoral thesis, 2018-11-22) -
Microbial nitrogen dynamics in organic and mineral soil horizons along a latitudinal transect in western Siberia
(Peer reviewed; Journal article, 2015-05-12)Soil N availability is constrained by the breakdown of N-containing polymers such as proteins to oligopeptides and amino acids that can be taken up by plants and microorganisms. Excess N is released from microbial cells ... -
A Microbial Nitrogen Engine Modulated by Bacteriosyncytia in Hexactinellid Sponges: Ecological Implications for Deep-Sea Communities
(Journal article; Peer reviewed, 2021-03-17)Hexactinellid sponges are common in the deep sea, but their functional integration into those ecosystems remains poorly understood. The phylogenetically related species Schaudinnia rosea and Vazella pourtalesii were herein ... -
Microbial winter and spring bloom dynamics in a high Arctic fjord
(Master thesis, 2014-06-02)Knowledge of the seasonal dynamics within the Arctic marine microbial network is scarce, particularly during the polar night period. The abundances of different microbial groups in Adventfjorden, Svalbard were investigated ... -
Microbiological aspects of fish handling and processing in the Norwegian pelagic sector
(Doctoral thesis, 2015-03-17)Most global marine fish resources seem to have reached their limit of sustainable exploitation, whereas the demand for high quality fish products is still increasing. The fish sector needs to comply with the growing market ... -
Microbiological assessment along the fish production chain of the Norwegian pelagic fisheries sector - Results from a spot sampling programme
(Peer reviewed; Journal article, 2015-10)Microbes play an important role in the degradation of fish products, thus better knowledge of the microbiological conditions throughout the fish production chain may help to optimise product quality and resource utilisation. ... -
The Microbiome and Occurrence of Methanotrophy in Carnivorous Sponges
(Peer reviewed; Journal article, 2016-11-09)As shown by recent studies, filter-feeding sponges are known to host a wide variety of microorganisms. However, the microbial community of the non-filtering carnivorous sponges (Porifera, Cladorhizidae) has been the subject ... -
Microbiome dataset from a marine recirculating aquaculture system (RAS) for salmon post-smolt production in Norway
(Journal article; Peer reviewed, 2022)A marine aquaculture recycling system (RAS) for the production of post-smolt was monitored for microbial community structures during the first year of operation. Sample material was obtained monthly from the biofilter ... -
Microbiomes of Hadal Fishes across Trench Habitats Contain Similar Taxa and Known Piezophiles
(Journal article; Peer reviewed, 2022)Hadal snailfishes are the deepest-living fishes in the ocean, inhabiting trenches from depths of ∼6,000 to 8,000 m. While the microbial communities in trench environments have begun to be characterized, the microbes ... -
Micromonas versus virus: New experimental insights challenge viral impact
(Peer reviewed; Journal article, 2017-05)Viruses have recurrently been hypothesized as instrumental in driving microbial population diversity. Nonetheless, viral mediated co-existence of r/kstrategists, predicted in the Killing-the-Winner (KtW) hypothesis, remains ... -
Micronekton biomass distribution, improved estimates across four north Atlantic basins
