Managing the shift to anoxia : regulatory phenomena in denitrifying bacteria, sources and sinks of N2O
(PhD thesis;2023:20, Doctoral thesis, 2023)Denitrification is the dissimilatory reduction of nitrate and nitrite to dinitrogen (N2), via nitric oxide (NO) and nitrous oxide (N2O), carried out by a wide range of prokaryotes when oxygen is scarce. The individual ... -
Lipids in Norwegian seaweed : an investigation of the fatty acids and glyceroglycolipids in selected seaweed
(PhD Thesis;2021:2, Doctoral thesis, 2021)Tang og tare er fornybare ressurser som har et enormt potensial som kilder til både mat og fôr. Markedsverdien kan i tillegg økes gjennom ekstraksjon av bioaktive fyto-kjemikalier. Lipider er forbindelser av interesse både ... -
Bacterial strain diversity and competition strategies in the infant gut
(PhD Thesis;2025:36, Doctoral thesis, 2025)The early bacterial establishment in the infant gut holds implications for overall, lifelong health. Although the infant gut microbiota has been extensively investigated, we still have limited knowledge about the sources ... -
Computational characterization of lytic polysaccharide monooxygenases and metalloorganic copper-complexes

Physiology of denitrification in bradyrhizobia and their potential as strong sinks for the greenhouse gas N2O
(PhD thesis;2022:40, Doctoral thesis, 2022)Nitrous oxide (N2O) is a major greenhouse gas, 300 times stronger than CO2 and it is also a main ozone-depleting substance that destroys the stratospheric ozone layer. N2O can be produced and emitted to the atmosphere by ... -
Somatic cell counts and their impact on Norwegian goat milk quality
(PhD thesis;2025:39, Doctoral thesis, 2025)Somatic cell count (SCC) is a key indicator of milk quality and udder health in dairy production. While SCC in cow milk is primarily used as a diagnostic tool for mastitis, its interpretation in goat milk is more complex ... -
Docosahexaenoic acid production by thraustochytrids : monitoring and optimization of bioprocesses
(PhD Thesis;2025:12, Doctoral thesis, 2025)The dietary omega-3 fatty acid docosahexaenoic acid (DHA) is associated with a wide spectrum of health benefits. However, the increasing demand for this essential fatty acid surpasses the supply from traditional sources ... -
Exploring utilization of β-mannans in gut microbiomes : key enzymes and beneficial properties
(PhD Thesis;2025:9, Doctoral thesis, 2025)β-Mannans are hemicelluloses that are widely distributed in the human diet, either as food additives or as constituents in foods like legumes, bananas, coffee beans, and cereals. These fiber structures are diverse and ... -
Evaluation of the leaderless bacteriocins EntEJ97s and EntK1 as novel treatment options against antibiotic resistant enterococci
(PhD Thesis;2025:19, Doctoral thesis, 2025)The discovery of antibiotics was revolutionary for mankind, but currently the world is presented with a looming antibiotic-resistance crisis. One of the important steps to combat this crisis is to discover new treatment ... -
Synthetic Approach Towards the Dipeptide Portion of Okeaniamide A
(Master thesis, 2024)Okeaniamides A and B were isolated from an Okiania species marine cyanobacterium in 2023. These were found to increase small insulin sensitive adipocytes and may help alleviate symptoms of type 2 diabetes, but further ... -
Characterizing putative fratricins from three streptococcal species
(Master thesis, 2024)Natural transformation is a naturally occurring form of horizontal gene transfer in species that are known to be competent. It is a process driven by the uptake of exogenous homologous DNA, and plays a crucial role in the ... -
Production of Recombinant LysM-Fuison Proteins for Non-GMO Anchoring on Lactic Acid Bacteria
(Master thesis, 2024)Lactic acid bacteria (LAB) are traditionally used in the production and preservation of food and are natural inhabitants of the human gastrointestinal tract. This makes LAB generally regarded as safe for consumption. Some ... -
Prediksjon av ekosystem status fra eDNA
(Master thesis, 2024)Fiskeoppdrett, eller akvakultur, har blitt en viktig global kilde til sjømat. Samtidig medfører det miljøutfordringer som kan påvirke økosystemer og biologisk mangfold. Overvåking av miljøstatus er avgjørende for å håndtere ... -
Development of anaerobic high cell density cultivation for sustainable single-cell protein production using denitrification
(PhD Thesis;2025:10, Doctoral thesis, 2025)Future food production faces the immense challenge of feeding a growing population with an increasing demand for resource-intensive food in a sustainable way. The high environmental footprint of conventional food production ... -
Identifying lignocellulose-degrading strategies in denitrifying microbial communities using meta-omics approaches
(PhD thesis;2024:73, Doctoral thesis, 2024)Microorganisms are everywhere, and millions of species are estimated to exist; however, only a small fraction have been isolated and in-depth characterized. For this reason, many habitats remain largely unexplored and ... -
Bioinformatic approaches for the prediction of seafloor ecological state from Nanopore 16SrRNA gene data
(PhD thesis;2024:79, Doctoral thesis, 2024)The increasing anthropogenic pressures, particularly from industries and activities like intensive aquaculture affect marine benthic ecosystems. This context requires immediate implementation of frequent and effective ... -
Elucidating the biology of bovine mastitis pathogens by novel molecular tools
(PhD Thesis;2024:81, Doctoral thesis, 2024)Staphylococcus aureus and Streptococcus dysgalactiae are major pathogens responsible for bovine mastitis, a significant disease that adversely affects animal health and imposes considerable economic burdens on the dairy ... -
Structural and mechanistic aspects of the type-3 copper protein tyrosinase
(PhD Thesis;2024:80, Doctoral thesis, 2024)Tyrosinases (TYRs) are type-3 copper proteins that catalyze the hydroxylation and oxidation of mono- and diphenols, respectively. These reactions are the rate-limiting steps in the biosynthesis of melanin, photoprotective ... -
De Novo Design of Copper Enzymes Using RFdiffusion
