Safety in numbers: multiple occurrences of highly similar homologs among Azotobacter vinelandii carbohydrate metabolism proteins probably confer adaptive benefits
(Journal article; Peer reviewed, 2014)Background Gene duplication and horizontal gene transfer are common processes in bacterial and archaeal genomes, and are generally assumed to result in either diversification or loss of the redundant gene copies. However, ... -
Salinity Acclimation Strategies in Nitrifying Bioreactors
(Peer reviewed; Journal article, 2022)Several industries, including aquaculture, produce effluents with high or varying salt concentrations. The treatment of such effluents by the biological nitrification process can be challenging, as the microbes performing ... -
Salinity as a driver for microbial community structure in reactors for nitrification and anammox
(Doctoral theses at NTNU;2016:365, Doctoral thesis, 2016)The removal of nitrogen from wastewater has become an important part of the overall treatment process due to the significant impact of nitrogen compounds (NH4–N, NOx–N) on the environment and the more stringent legislation ... -
Salting of Muscle Foods: Effects of processing conditions and sodium reduction
(Doctoral thesis at NTNU;2014:335, Doctoral thesis, 2014)The present thesis aims at investigating (i) salt distribution in the lean fish- and meat minces, (ii) the effect of different ions on the extractability of salt soluble proteins, and (iii) the possibility to decrease salt ... -
A salty start: Brackish water start-up as a microbial management strategy for nitrifying bioreactors with variable salinity
(Peer reviewed; Journal article, 2020)Nitrifying biofilms developed in brackish water are reported to be more robust to salinity changes than freshwater biofilms. This makes them a promising strategy for water treatment systems with variable salinity, such as ... -
Sammenligning av ekstraksjonsmetoder for vitamin A og vitamin E i grønnkål og crispisalat
(Bachelor thesis, 2024)Oppgavens hovedmål var å etablere en god “in-house” metode for ekstraksjon av vitamin A (i form av β-karoten) og vitamin E (i form av α-tokoferol) i plantemateriale som grønnkål og crispisalat. Hensikten var at metoden ... -
Sammenligning av kjemisk og enzymatisk ekstraksjonsmetoder for melorm Tenebrio molitor og melormskall
(Bachelor thesis, 2023)Bakgrunn - Kitin er et polysakkarid som det finnes rikelig av i naturen. Det kan ekstraheres fra melorm og brukes i næringsmiddelindustrien. Mål - Målet for prosjektet var å ekstrahere kitin fra melorm og melormskall ved ... -
Sammenligning av selektive dyrkningsmedier for påvisning av Aeromonas
(Bachelor thesis, 2019)Metoden for påvisning av Aeromonas utarbeidet av Nordisk Metodikkomité for næringsmidler (NMKL) er ikke optimal. Dyrkningsmediet Stivelses Ampicillin Agar (SAA) som blir benyttet etter denne standarden har vist seg å være ... -
Sammenligning av stabiliseringsmetoder for å oppnå mikrobiell stabilitet i mjød
(Bachelor thesis, 2019)Hovedmålet var å undersøke hvilke stabiliseringsmetoder som kunne bidra med å oppnå mikrobiell stabilitet i mjød med innhold av restsukker, og unngå en potensiell refermentering i emballert produkt. Samt utforske hvilken ... -
Sampling and Survival of Salmonella Typhimurium on Surfaces
(Master thesis, 2013)It is important to determine both presence and number of viable microorganisms on the surface of utensils, work surfaces and other equipment in contact with food. Cross-contamination of foodborne pathogens on food-contact ... -
Scan-o-matic: High-Resolution Microbial Phenomics at a Massive Scale
(Journal article; Peer reviewed, 2016)The capacity to map traits over large cohorts of individuals-phenomics-lags far behind the explosive development in genomics. For microbes, the estimation of growth is the key phenotype because of its link to fitness. We ... -
Screening of lactic acid bacteria to detect potent biosorbents of lead and cadmium
(Peer reviewed; Journal article, 2019)In this study, the ability of 19 strains of local Lactic acid bacteria in reducing Cd (II) and Pb (II) has been evaluated, in vitro. The average uptake of metal ions was determined per cell and the effect of dead and live ... -
Searching for efficient methods of extraction and characterization of protein from Saccharina latissima and Alaria esculenta.
(Master thesis, 2020)Abstract Growing population and alteration of the environment due to climate change and human im-pact, water scarcity and reduction of the available arable land demand search for alternative food sources. To meet the ... -
Seasonal variation in chemical composition and contaminants in European plaice (Pleuronectes Platessa) originated from the west-coast of Norway
(Peer reviewed; Journal article, 2022)The seasonal effect on chemical composition and contaminants in European plaice (Pleuronectes platessa) captured in Norwegian waters was investigated in three seasons (September, December, April). Fillets were compared by ... -
