Genetic Regulation of Diatom Photosynthesis
(Chapter, 2024)Diatoms (Bacillariophyceae) are considered to be the most diverse class of algae, including as many as 250 genera and having possibly as many as 200,000 species. Because of their complex evolutionary history, they are ... -
Identification and characterization of antibiotic resistance and disinfectant susceptibility of Enterococcus spp. from Norwegian salmon industry, encompassing wastewater, rest raw materials and by-products
(Master thesis, 2024)Salmon aquaculture is one of the fastest-growing sectors in global food production. From fish to final product, it is critical to control all food safety aspects. This necessitates the assessment of antimicrobial resistant ... -
Exploring Cellular Origins of Lung Cancer Genes: A Computational Approach Using Marker Genes and Genomic Databases
(Master thesis, 2024)Lungekreft er fortsatt en ledende årsak til kreftrelatert dødelighet globalt, noe som krever avansert forskning for å avdekke de molekylære grunnlagene. Denne studien undersøker celletype-opprinnelsen til differensielt ... -
CsgA gatekeeper residues control nucleation but not stability of functional amyloid
(Journal article; Peer reviewed, 2024)Functional amyloids, beneficial to the organism producing them, are found throughout life, from bacteria to humans. While disease-related amyloids form by uncontrolled aggregation, the fibrillation of functional amyloid ... -
Kartlegging av potensielt bærekraftige alternativer til petroleumsprodusert plastemballasje for næringsmidler i det norske markedet som har lav vannaktivitet, med utgangspunkt i tørket pasta.
