(Master thesis, 2022)Norge er en verdensledende produsent av atlantisk oppdrettslaks, og står for 51% av den globale produksjonen. Kontroll og forebygging av patogene bakterier, slik som Listeria monocytogenes (L. monocytogenes) i miljø der ... -
Localization and Function of Factor XIII at the Fetal-Uterine Interface: Recurrent Abortion Management Issues
(Master thesis, 2012)The blood coagulation Factor XIII (FXIII) is a transglutaminase catalyzing γ-glytamyl ε-lysine crosslinks between various molecules. It is most known for its role in crosslinking fibrin and stabilizing the blood clot in ... -
Long-term microbial community structures and dynamics in a commercial RAS during seven production batches of Atlantic salmon fry (Salmo salar)
(Peer reviewed; Journal article, 2023)The microbiota of recirculating aquaculture systems (RAS) is of major importance for optimal fish health. However, the microbial communities in commercial RAS are highly complex and more knowledge is needed to potentially ... -
Looking for the Big Picture:Genome-Based Approaches to Improve Alginate Production in Azotobacter vinelandii
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:18, Doctoral thesis, 2014)Alginates are commercially important polysaccharides with a wide range of industrial and technological applications. Polymer chain length and monomer distribution greatly affect the material properties, which makes different ... -
Loss of ALBINO3b insertase results in truncated light-harvesting antenna in diatoms
(Journal article; Peer reviewed, 2019)The family of chloroplast ALBINO3 (ALB3) proteins function in the insertion and assembly of thylakoid membrane protein complexes. Loss of ALB3b in the marine diatom Phaeodactylum tricornutum leads to a striking change of ... -
Low-field NMR and MRI studies of fish muscle: Effects of raw material quality and processing
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:136, Doctoral thesis, 2009)The present thesis aims at using non-invasive and non-destructive NMR techniques to contribute to a further understanding of fish tissue composition and its characteristics. Moreover, it aims at investigating the water ... -
Lønnsom foredling av sjømat i Norge
(Research report, 2014)Automatisering og robotisering av produksjonsprosesser forventes å få en sentral plass i samfunnet. I en utredning fra Stiftelsen for Strategisk Forsking i Sverige, forventes det at i løpet av ... -
Macromolecular acidic coating increases shelf life by inhibition of bacterial growth
(Journal article; Peer reviewed, 2018)The sensitivity of microorganisms to low pH can be utilized in food protection by preparing coatings based on macromolecular acids. Due to limited diffusivity of macromolecules low pH occurs primarily at the surface, while ... -
Major faecal microbiota shifts in composition and diversity with age in a geographically restricted cohort of mothers and their children
(Journal article; Peer reviewed, 2014)Despite the importance, the diversity of the human infant gut microbiota still remains poorly characterized at the regional scale. Here, we investigated the faecal microbiota diversity in a large 16S rRNA gene data set ... -
Management of biofloc concentrations as an ecological strategy for microbial control in intensive shrimp culture
(Peer reviewed; Journal article, 2021)This study investigated if the intensity of sedimentation through settling tanks modifies the bacterial community composition of biofloc systems and affects performance of shrimp. A 50-day trial, which was conducted with ... -
Managing the microbial community of marine fish larvae: a holistic perspective for larviculture
(Journal article; Peer reviewed, 2018)The availability of high-quality juveniles is a bottleneck in the farming of many marine fish species. Detrimental larvae-microbe interactions are a main reason for poor viability and quality in larval rearing. In this ... -
Manganese acquisition is facilitated by PilA in the cyanobacterium Synechocystis sp. PCC 6803
(Journal article; Peer reviewed, 2017)Manganese is an essential element required by cyanobacteria, as it is an essential part of the oxygen-evolving center of photosystem II. In the presence of atmospheric oxygen, manganese is present as manganese oxides, which ... -
Mannuronan C-5 Epimerases Suited for Tailoring of Specific Alginate Structures Obtained by High-Throughput Screening of an Epimerase Mutant Library
(Journal article; Peer reviewed, 2013)The polysaccharide alginate is produced by brown algae and some bacteria and is composed of the two monomers, β-d-mannuronic acid (M) and α-l-guluronic acid (G). The distribution and composition of M/G are important for ... -
