Microbial interactions shape cheese flavour formation
(Peer reviewed; Journal article, 2023)Cheese fermentation and flavour formation are the result of complex biochemical reactions driven by the activity of multiple microorganisms. Here, we studied the roles of microbial interactions in flavour formation in a ... -
Cortisol Metabolites as Indicators of Acute Stress in Farmed Atlantic Salmon (Salmo salar): Biological Matrices and Analytical Methods
(Doctoral theses at NTNU;2025:122, Doctoral thesis, 2025)English summary A Key to Better Fish Welfare Farming salmon in high biomass systems can be stressful for the fish. Too much stress can make them more susceptible to diseases and handling, which can lead to injuries, ... -
Extraction of proteinaceous components and biominerals from cold water fish fileting side streams: a review
(Journal article; Peer reviewed, 2024)Fileting is a popular form of processing methods and in addition to being sold fresh or frozen, filets are used for preparation products battered and breaded filets. This generates considerable amount of side streams like ... -
Insights into the quality changes of edible sea urchin (Echinus esculentus) gonads during ice storage
(Journal article; Peer reviewed, 2024)The study aimed to assess the quality changes of E. esculentus gonads during 14-days of ice storage. Microbial quality and community composition succession were examined using both culture-dependent and independent methods. ... -
Effects of Oxygen Limitation and High Plasmid Copy Number on Growth, Metabolism and Recombinant Protein Production in Escherichia coli BL21
(Master thesis, 2025)Rekombinant proteinproduksjonsindustri har blomstret de siste årene og er et ekspanderende felt av økende økonomisk og sosial betydning. Blant vertsorganismer er Escherichia coli (E. coli) den mest brukte, på grunn av dens ... -
Evaluation of Atlantic cod hydrolysate properties in innovative freeze concentration techniques
(Journal article; Peer reviewed, 2025)This study investigates Atlantic cod's (Gadus morhua) physicochemical and rheological properties throughout various stages of the hydrolysis process to assess the feasibility of integrating a high-temperature heat pump ... -
A proteomics–bioinformatics approach to assess the molecular and physicochemical properties of brewer's spent grain protein concentrates: Effect of alkali-heat treatment
(Peer reviewed; Journal article, 2024)Brewer's spent grain (BSG) can serve as an attractive protein source due to its low cost and excellent nutritional and functional attributes. Alterations induced by protein extraction process in the BSG protein molecules ... -
Automation-aided construction and characterization of Bacillus subtilis PrsA strains for the secretion of amylases
(Peer reviewed; Journal article, 2024)Proteins face an obstacle race on their way to successful folding. Chaperones facilitate the proper folding of proteins by ensuring they remain on the correct path toward their final tertiary structure. In bacilli, the ... -
SOS genes are rapidly induced while translesion synthesis polymerase activity is temporally regulated
(Journal article; Peer reviewed, 2024)The DNA damage inducible SOS response in bacteria serves to increase survival of the species at the cost of mutagenesis. The SOS response first initiates error-free repair followed by error-prone repair. Here, we have ... -
