A comparative study of Atlantic salmon chilled in refrigerated seawater versus on ice: from whole fish to cold-smoked fillets
(Peer reviewed; Journal article, 2020)Water and salt uptake, and water holding capacity (WHC) of whole gutted Atlantic salmon superchilled at sub-zero temperatures in refrigerated seawater (RSW) were compared to traditional ice storage. Following the entire ... -
Enzyme-Constrained Models and Omics Analysis of Streptomyces coelicolor Reveal Metabolic Changes that Enhance Heterologous Production
(Journal article; Peer reviewed, 2020)Many biosynthetic gene clusters (BGCs) require heterologous expression to realize their genetic potential, including silent and metagenomic BGCs. Although the engineered Streptomyces coelicolor M1152 is a widely used host ... -
Rheology of skin mucus from yolk-sac salmon fry

Effect of chilling technologies on water holding properties and other quality parameters throughout the whole value chain: From whole fish to cold-smoked fillets of Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)The effect of different chilling technologies on water holding and quality parameters was investigated on Atlantic salmon throughout the entire value chain. Chilling technologies of whole fish before filleting, included ... -
Potential of innovative pre-treatment technologies for the revalorisation of residual materials from the chicken industry through enzymatic hydrolysis
(Peer reviewed; Journal article, 2020)The effect of microwave, ultrasound and high-pressure pre-treatment prior to enzymatic hydrolysis of mechanically deboned chicken residuals was evaluated. Increased protein extraction yield was observed for high-pressure ... -
Effect of design geometry, exposure energy, cytophilic molecules, cell type and load in fabrication of single-cell arrays using micro-contact printing
(Journal article; Peer reviewed, 2020)In this study a range of factors influencing the fabrication of single-cell arrays (SCAs) are identified and investigated. Micro-contact printing was used to introduce spots coated with polyethyleneimine or Matrigel on ... -
Assessment of Astaxanthin Accumulation in Hepatocytes of Atlantic Salmon Fed Different Diets Using NMR Spectroscopy
(Journal article; Peer reviewed, 2020)This study aimed to assess the astaxanthin (Ax) accumulation in hepatocytes isolated from farmed Atlantic salmon fed different diets (rich marine, poor, poor with marine phospholipids (MPL) and poor with docosahexaenoic ... -
Study and Engineering of Gram- Negative Bacteria as Hosts for Production of Recombinant Proteins and Biopolymers
(Doctoral theses at NTNU;2020:173, Doctoral thesis, 2020)Gram-negative bacteria are a large group of prokaryotic organisms that thrive in diverse environments and differ in terms of structure and metabolism. They are capable of producing a variety of natural compounds and ... -
Modelling biodegradation of crude oil components at low temperatures
(Others, 2020)For oil spilled at sea, the main weathering processes are evaporation, emulsification, photo-oxidation, dispersion and biodegradation. Of these, only biodegradation may completely remove hydrocarbons from the environment ... -
Teaching complex molecular simulation algorithms: Using self‐evaluation to tailor web‐based exercises at an individual level
(Peer reviewed; Journal article, 2020)It is quite challenging to learn complex mathematical algorithms used in molecular simulations, stressing the importance of using the most advantageous teaching methods. Ideally, individuals should learn at their pace and ... -
Mechanistic basis of substrate–O2 coupling within a chitin-active lytic polysaccharide monooxygenase: An integrated NMR/EPR study
(Peer reviewed; Journal article, 2020)Lytic polysaccharide monooxygenases (LPMOs) have a unique ability to activate molecular oxygen for subsequent oxidative cleavage of glycosidic bonds. To provide insight into the mode of action of these industrially important ... -
A new fluorimetric method for simultaneous determination of lipid and protein hydroperoxides in muscle foods with the use of diphenyl-1-pyrenylphosphine (DPPP)
(Peer reviewed; Journal article, 2020)A new fluorimetric assay for simultaneous determination of lipid and protein hydroperoxides in muscle foods by the use of diphenyl-1-pyrenylphosphine (DPPP) was proposed in the study. Non-fluorescent DPPP that reacts with ... -
Physiological and flesh quality consequences of pre-mortem crowding stress in Atlantic mackerel (Scomber scombrus)
(Peer reviewed; Journal article, 2020)In commercial wild capture pelagic fisheries it is common practice to crowd catches to high densities to allow efficient pumping onboard. Crowding during the final stages of purse seine capture for small pelagic species ... -
Dual UTR-A novel 5′ untranslated region design for synthetic biology applications
(Peer reviewed; Journal article, 2020)Bacterial 50 untranslated regions of mRNA (UTR) involve in a complex regulation of gene expression; however, the exact sequence features contributing to gene regulation are not yet fully understood. In this study, we ... -
Establishment of a functional system for recombinant production of secreted proteins at 50 °C in the thermophilic Bacillus methanolicus
(Peer reviewed; Journal article, 2020)Background The suitability of bacteria as microbial cell factories is dependent on several factors such as price of feedstock, product range, production yield and ease of downstream processing. The facultative methylotroph ... -
Food-Loss Control at the Macronutrient Level: Protein Inventory for the Norwegian Farmed Salmon Production System
(Peer reviewed; Journal article, 2020)The growing world population and the growing need for food are raising the importance of more efficient and sustainable food production systems. Food loss is a significant global challenge and a major stressor on natural ... -
Functional characterization of three Azotobacter chroococcum alginate-modifying enzymes related to the Azotobacter vinelandii AlgE mannuronan C-5-epimerase family
(Peer reviewed; Journal article, 2020)Bacterial alginate initially consists of 1-4-linked beta-D-mannuronic acid residues (M) which can be later epimerized to alpha-L-guluronic acid (G). The family of AlgE mannuronan C-5-epimerases from Azotobacter vinelandii ... -
