How enzyme and substrate concentration influence the synergy effect on chitin degradation by SmChiA and SmAA10A
(Master thesis, 2023)Motstandsdyktige polysakkarider som cellulose og kitin er rikelig produsert av organismer i naturen, og nedbrytning av disse til produkter av verdi holder et stort potensial for bruk i en bærekraftig fremtid som innebærer ... -
Investigating the Role of Methylation and Glycosylation in Protecting Fungal Lytic Polysaccharide Monooxygenases from Auto-Oxidative Inactivation
(Master thesis, 2023)Global warming and the pending energy crisis pressure the search for effective utilization of renewable energy sources. Biomass has long been discussed to be such an energy source, but the recalcitrant constituents, such ... -
DNA methylation in a nutritional and social context : a study of cytosine modifications in honey bee (Apis mellifera) workers
(PhD Thesis;2023:10, Doctoral thesis, 2023)Intergenic DNA methylation is widespread in both the animal and plant kingdoms. Its presence in exons is believed to be dynamic and suggests its involvement in the regulation of alternative splice variants. In addition, ... -
Syntese mot glykonjugater med anilin derivater
(Master thesis, 2024)Palladiumkatalysatoren [(2,9-dimetyl-1,10-fenantrolin)Pd(µ-OAc)]2(OTf)2 ble benyttet til å selektiv oksidere metyl-β-D-xylopyranosid i C-3 posisjonen, og reagere denne forbindelsen videre til ulike UV-aktive glykokonjugat. ... -
Determination of antibiotic resistance in clinical isolates of Pseudomonas aeruginosa
(Master thesis, 2023)Bakterien Pseudomonas aeruginosa er en gram-negativ opportunistisk patogen bakterie som kan infisere mennesker med nedsatt immunforsvar, slik som pasienter født med den recessivt arvelige sykdommen cystisk fibrose (CF). ... -
Identification of Specific N-Acyl-L-Homoserine Lactones by Use of Direct Infusion ESI-MS
(Master thesis, 2023)Gram-negative bakterier utgjør en stor andel av livet på jorda. En forståelse av deres kommunikasjonsmetoder er nødvendig for vår forståelse av deres oppførsel. Med dypere innsikt i kommunikasjonsmetodene deres kan vi ... -
Objective methods of classification for beef- and pork carcases as a basis for evaluation of carcase yield
(PhD Thesis;2024:13, Doctoral thesis, 2024)Yield within the meat industry refers to the ratio and weight of tissues from the carcase. Carcase classification gives each carcase grades that determine the price paid for the carcase. Two aspects are especially important ... -
Navigating Model Drift: A Case Study on Classifying Occupations Using Textual Data
(Master thesis, 2023)Data underlying any machine learning model is prone to change over time in a process called model drift. The extent of change and effect on the model performance should be monitored in production settings to avoid decreasing ... -
Exploring variability of perceptions and heterogeneity of opinions
(Dr. Philos. thesis;2023:2, Doctoral thesis, 2023)The manuscripts in this thesis introduce new sensometric methods. Some methods investigate the variability of perceptions in sensory studies involving trained or consumer panels. Other methods explore the heterogeneity of ... -
Fungi to leather: The use of wood-digesting fungi to produce alternative materials.
(Master thesis, 2023)There is an increasing demand for ecofriendly alternative materials. One approach for new material technology may be mycelium-based materials. Mycelium is a complex network of cells formed by fungi, which has been utilized ... -
