Biochemical investigation of catalysis by lytic polysaccharide monooxygenases
Loose, Jennifer Sarah Maria (PhD Thesis;2016:69, Doctoral thesis, 2018-05-04)Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that catalyze the oxidative cleavage of glycosidic bonds in the presence of dioxygen and an external electron donor. Currently, these enzymes are ... -
Characterization of a Glycoside hydrolase family 50 member PaGH50A from Pseudomonas aeruginosa and exploring the enzyme’s potential in modulating biofilm formation
Farah, Hibaq Ahmed (Master thesis, 2022)Pseudomonas aeruginosa is an opportunistic human pathogen that causes acute and chronic lung infections in individuals with compromised immune systems. The bacterium is wide spread in the environment and especially persistent ... -
Deteksjon og kvantifikasjon av HRV87 i A549 celler med og uten Neu5Ac in vitro
Ørstenvik, Hanne Lillerovde (Master thesis, 2021)Forkjølelse er et dagligdags problem som forårsakes av ulike varianter av rhinovirus. Rhinovirus er en av de vanligste årsakene til luftveisinfeksjoner og står for omlag 50 % av tilfellene. Forskningslitteraturen viser til ... -
Discovery and characterization of bacterial enzymes for processing of lignocellulosic biomass
Jensen, Marianne Slang (PhD Thesis;2019:62, Doctoral thesis, 2019)Utilization of non-edible biomass as a source of renewable carbon can assist the transition to a sustainable bioeconomy. Such biomass includes non-edible plant materials commonly referred to as lignocellulose. Lignocellulose ... -
Discovery and characterization of cellulose-active lytic polysaccharide monooxygenases
Forsberg, Zarah Kristina (PhD Thesis;2014:62, Doctoral thesis, 2014)The efficient depolymerization of lignocellulosic biomass to fermentable sugars by enzymatic hydrolysis is a key step in the transition towards a more environmentally friendly and sustainable bio-economy. However, the ... -
Discovery and characterization of enzymes acting on chitin
Tuveng, Tina Rise (PhD Thesis;2017:71, Doctoral thesis, 2017)In the shift from a fossil-based to a bio-based economy, exploration of renewable recourses is needed. Chitin is considered the second most abundant polysaccharide on Earth, after cellulose, and its water-soluble derivatives ... -
Discovery, expression, and characterization of novel laccases derived from marine bacteria
Neeraas, Priscilla Cassandra (Master thesis, 2019)Lignocellulose is the most abundant biomass on Earth and is primarily composed of three organic polymers; cellulose, hemicellulose, and lignin. Established technology exists to produce useful products such as fuels and ... -
Enzymatic conversion of cotton textiles
Austad, Anna (Master thesis, 2018)Cotton textiles are mass-produced worldwide, but little is done to recirculate this material that is rich in cellulose. Indeed, cellulosic textiles represent a potential resource for the production of glucose, that further ... -
Exploration of an alginate lyase targeting the biofilm in Pseudomonas aeruginosa
Hoff, Mildrid Angard (Master thesis, 2022)Pseudomonas aeruginosa is an opportunistic gram-negative bacterium capable of colonizing immunosuppressed patients such as those with cystic fibrosis. A P. aeruginosa infection could lead to mortality since some strains ... -
The farmed Atlantic salmon (Salmo salar) skin-mucus microbiome : bacterial diversity, mucus degrading potential and putative virulence factors
Minniti, Giusi (PhD Thesis;2018:34, Doctoral thesis, 2018)Norway is the main producer and exporter of Atlantic salmon worldwide, representing one of the pillars of the Norwegian economy. Today, about 1.2 million tons of salmonids are produced in Norway and a five-fold increase ... -
Increasing sensitivity of a particle-enhanced turbidimetric immunoassay for quantitative analysis of calprotectin
Hidden, Clara Mathilde (Master thesis, 2019)Calprotectin is a protein that is released by activated leukocytes and monocytes. Increased levels of the protein are found in patients with inflammatory and autoimmune conditions, including juvenile idiopathic arthritis ... -
Light-driven lytic polysaccharide monooxygenase (LPMO)-catalyzed solubilization of polysaccharides
Kommedal, Eirik Garpestad (PhD Thesis;2022:38, Doctoral thesis, 2022)Lytic polysaccharide monooxygenases (LPMOs) are a recently discovered family of enzymes that catalyze oxidative cleavage of glycosidic bonds in insoluble polysaccharides at a liquid-solid interface. These enzymes are ... -
Proteolyse ved eksogene enzymer gir mulige effekter på spisekvalitet, proteinfordøyelse og bioaktivitet i Semitendinosus
Thormodsrud, Linn Christine (Master thesis, 2018)Mørhet er avgjørende når forbruker velger kjøttstykke. I framtidens kjøttproduksjon kan tilførsel av eksogene enzymer muligens bidra til forbedret mørhet i seige muskler som normalt brukes til prosessert kjøtt. Videre kan ... -
