Ultrafiltration of Saithe (Pollachius virens) Protein Hydrolysates and Its Effect on Antioxidative Activity
(Peer reviewed; Journal article, 2021)The whitefish industry generates a huge amount of rest raw material, which is currently wasted or underutilized in the production of low-value products such as animal feed. While fish muscle is the primary product of use ... -
Unaided efficient transglutaminase cross-linking of whey proteins strongly impacts the formation and structure of protein alginate particles
(Peer reviewed; Journal article, 2022)There is a dogma within whey protein modification, which dictates the necessity of pretreatment to enzymatic cross-linking of β-lactoglobulin (β-Lg). Here microbial transglutaminase (MTG) cross-linked whey proteins and ... -
Understanding structure/function relationships in nitrifying microbial communities after cross-transfer between freshwater and seawater
(Peer reviewed; Journal article, 2021)In this study, nitrification before and after abrupt cross-transfer in salinity was investigated in two moving bed biofilm reactors inoculated with nitrifying cultures that had adaptation to freshwater (FR) and seawater ... -
Undersøkelse av antibiotikaresistens hos miljøbakterier fra akvatiske miljø i Trondheim
(Bachelor thesis, 2024)I dag er antimikrobiell resistens (AMR) en av de største truslene mot verdens folkehelse. Spredning og utvikling av AMR er spesielt bekymringsfullt når patogene bakterier utvikler resistens mot flere ulike klasser antibiotika. ... -
Undersøkelse av antibiotikaresistens i ulike vannmiljøer i Trondheim
(Bachelor thesis, 2023)Antibiotikaresistens (AR) er et av dagens største helseproblem. Resistens mot antibiotika er naturlig blant bakterier, men dagens bekymring ligger i den økende forekomsten av multiresistente patogene bakterier som kan ... -
Undersøkelse av hvordan kaldrøkt laks påvirkes ved bruk av røyksyre i forhold til bøkeflis
(Bachelor thesis, 2019)Prosjektets hovedmål var å undersøke hvordan fysiokjemiske parametere i Atlantisk laks (Salmo salar) påvirkes når det benyttes røyksyre til å kaldrøyke fisken sammenlignet med kaldrøyking med bøkeflis. Laksen ble tørrsaltet, ... -
Unexpected Heterocyclization of Electrophilic Alkenes by Tetranitromethane in the Presence of Triethylamine. Synthesis of 5-Nitroisoxazoles
(Peer reviewed; Journal article, 2019)A novel reaction of tetranitromethane with electrophilic alkenes in the presence of triethylamine affording substituted 5-nitroisoxazoles is described. Triethylamine reacts with tetranitromethane to generate N-nitrotriet ... -
Unique photosynthetic electron transport tuning and excitation distribution in heterokont algae
(Journal article; Peer reviewed, 2019)Heterokont algae are significant contributors to marine primary productivity. These algae have a photosynthetic machinery that shares many common features with that of Viridiplantae (green algae and land plants). Here we ... -
Unlocking the genomic potential of aerobes and phototrophs for the production of nutritious and palatable microbial food without arable land or fossil fuels
(Peer reviewed; Journal article, 2021)The increasing world population and living standards urgently necessitate the transition towards a sustainable food system. One solution is microbial protein, i.e. using microbial biomass as alternative protein source for ... -
Unraveling aquaculture-related stress in Atlantic salmon (Salmo salar) - Molecular responses and methodological insights
(Doctoral theses at NTNU;2025:13, Doctoral thesis, 2025)Aquaculture is a cornerstone of Norway’s food industry and offers sustainable solutions to meet the rising global demand for protein. As the sector grows, there is an increasing emphasis on fish welfare, not only for ethical ... -
Unravelling Formaldehyde Metabolism in Bacteria: Road towards Synthetic Methylotrophy
(Peer reviewed; Journal article, 2022)Formaldehyde metabolism is prevalent in all organisms, where the accumulation of formaldehyde can be prevented through the activity of dissimilation pathways. Furthermore, formaldehyde assimilatory pathways play a fundamental ... -
Untargeted metabolomic analysis of urine samples in the diagnosis of some inherited metabolic disorders
(Peer reviewed; Journal article, 2015)Background: Metabolomics is becoming an important tool in clinical research and the diagnosis of human diseases. It has been used in the diagnosis of inherited metabolic disorders with pronounced biochemical abnormalities. ... -
Unveiling the Potential of Extremolytes: Metabolic Engineering of Corynebacterium glutamicum for Thermal Stress Resistance
(Master thesis, 2024)Mikrobielle cellefabrikker har blitt bærekraftige alternativer til tradisjonelle produksjonsprosesser ved å produsere verdifulle stoffer som kjemikalier, legemidler og biodrivstoff. Til tross for deres potensial møter ... -
Upgrading Marine Oils from Cod (Gadus morhua) On-Board the Deep-Sea Vessels—From Waste to Value
(Peer reviewed; Journal article, 2023)Significant amounts of marine raw material are lost on-board the deep-sea vessels due to fast quality degradation. Optimal on-board handling and processing strategies can upgrade these resources from waste to food ingredients ... -
Uptake and biological response to zinc by the Diatom Thalassiosira pseudonana
