New broad-host-range Biological Tools for Metagenomics and Screening of Marine DNA Libraries
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:41, Doctoral thesis, 2011)The fact that only a minority of the microorganisms in environmental samples can be cultivated in the laboratory necessitates the use of metagenomics to better explore and exploit the huge source of genetic diversity ... -
A new fluorimetric method for simultaneous determination of lipid and protein hydroperoxides in muscle foods with the use of diphenyl-1-pyrenylphosphine (DPPP)
(Peer reviewed; Journal article, 2020)A new fluorimetric assay for simultaneous determination of lipid and protein hydroperoxides in muscle foods by the use of diphenyl-1-pyrenylphosphine (DPPP) was proposed in the study. Non-fluorescent DPPP that reacts with ... -
New insights into the biosynthesis of alginate in Pseudomonas fluorescens: from precursor synthesis to multiprotein factories
(Doctoral thesis at NTNU;2015:181, Doctoral thesis, 2015)Alginate is a biopolymer that has numerous industrial and medical applications due to its favorable material properties, which is greatly affected by the polymer chain length and monomer composition. Currently, all ... -
New natural products identified by combined genomics-metabolomics profiling of marine Streptomyces sp. MP131-18
(Journal article; Peer reviewed, 2017)Marine actinobacteria are drawing more and more attention as a promising source of new natural products. Here we report isolation, genome sequencing and metabolic profiling of new strain Streptomyces sp. MP131-18 isolated ... -
Next generation recombinant viral vectors: an investigation of enhancer driven transgene expression in the subthalamic nucleus after viral vector mediated transfection.
(Master thesis, 2020)Den subthalamiske kjernen (STN) inngår i en signalkrets i de basale gangliene (BG), og denne kretsen er dysfunksjonell hos pasienter med Parkinsons sykdom (PD), noe som resulterer i bevegelsesforstyrrelser. Dyp hjernestimulering ... -
Nitrification in marine RAS: Nitrifying capacity and nitrifying communities of biofilters in RAS for production of Atlantic cod and Atlantic salmon
(Master thesis, 2023)I denne masteroppgaven ble nitrifiseringskapasitet, sensitivitet for salinitet og de mikrobielle biofilmsamfunn i biofiltre operert ved høye saliniteter undersøkt. Lab-skala batch-eksperimenter ble utført med biofilm bærere ... -
Nitrifying biofilms deprived of organic carbon show higher functional resilience to increases in carbon supply
(Peer reviewed; Journal article, 2020)In nitrifying biofilms, the organic carbon to ammonia nitrogen (C/N) supply ratio can influence resource competition between heterotrophic and nitrifying bacteria for oxygen and space. We investigated the impact of acute ... -
NMR and fluorescence spectroscopies reveal the preorganized binding site in family 14 carbohydrate-binding module from human chitotriosidase
