Microbial community dynamics in three RAS with different salinities for production of Atlantic Salmon postsmolt
(Master thesis, 2015)Bacteria in the water interacts with the fish and can affect their health and survival. A stable microbial community in the rearing water can promote a good rearing environment for the fish. The purpose of this study was ... -
Microbial community dynamics in water and biofilm of recirculating aquaculture systems (RAS)
(Doctoral theses at NTNU;2022:383, Doctoral thesis, 2022)The microbial communities in recirculating aquaculture systems (RAS) are essential for optimal physicochemical water quality and fish health. Despite progress, there is still limited knowledge on microbial community dynamics ... -
Microbial dynamics in RAS water: Effects of adding acetate as a biodegradable carbon-source
(Journal article; Peer reviewed, 2019)This study evaluated the effect of an abrupt increase in easily biodegradable carbon (acetate) on bacterial activity and abundance in the water of recirculating aquaculture systems (RAS). The study included a batch experiment ... -
Microbial ecology and food safety of fresh retail sushi
(Doctoral theses at NTNU;2018:164, Doctoral thesis, 2018)Sushi is a traditional Japanese dish that has become a popular ready-to-eat (RTE) product available in retail stores. Retail sushi is usually offered as complete meals, packed in a plastic lidded tray with a claimed ... -
Microbial Enhanced Oil Recovery - Modeling and Numerical Simulations
(Master thesis, 2015)This thesis examines the process by which microbes are used to enhance oil recovery from subsurface reservoirs. A brief introduction to reservoirs is given and the possible effects of microbes are explained. A model is ... -
Microbial Exopolysaccharides: Evaluation of Glycosyltransferase GumM and 13C Isotope-Labeling of Bacterial Cellulose
(Master thesis, 2021)Mikrobielle eksopolysakkarider er en mangfoldig underkategori av ekstracellulære polymeriske stoffer som utskilles av mikroorganismer. Disse forbindelsene har som regel høy molekylvekt og består av monomerer som er ... -
Microbial Growth on Indoor Artificial Turf and Assessment of Suitable Disinfection Methods
(Bachelor thesis, 2021)Bakterievekst i kunstgress er et problem, spesielt på grunn av at nyere generasjoner av kunstgress (4G) inneholder organisk fyll istedenfor gummigranulat. Det organiske fyllet er mer miljøvennlig, men inneholder ikke ... -
Microbial quality of the copepod Acartia tonsa for use as live feed for marine larvae: A process-evaluation
(Master thesis, 2020)Copepoder har vist seg å være et godt levendefôr-alternativ for marine larver. Overlegent sammenlignet med mer tradisjonelt levendefôr, som Arteima og rotatorier. Dette gjør copepoder til en viktig fôrkilde innenfor ... -
Microbial Therapeutics and Oral Delivery Systems – An Evaluation of Microencapsulation of Microbiota
(Master thesis, 2020)The understanding of the role of microorganisms in human health and disease has rapidly expanded in recent years. The emerging field of microbial therapeutics refers to the notion of introducing exogenous microbes to the ... -
Microbial water quality of the copepod Acartia tonsa in cultures for use as live feed
(Peer reviewed; Journal article, 2022)Live feed is important for rearing of marine larvae in the aquaculture industry and copepods have shown some superior qualities compared to Artemia and rotifers. Whereas the nutritional composition is one factor contributing ... -
Microbial-induced calcium carbonate precipitation: An experimental toolbox for in situ and real-time investigation of micro-scale pH evolution
(Peer reviewed; Journal article, 2020)Concrete is the second most consumed product by humans, after water. However, the production of conventional concrete causes more than 5% of anthropogenic CO2 emissions and therefore there is a need for emission-reduced ... -
Microbiological Assessment of Disinfection on Indoor Artificial Turf
(Bachelor thesis, 2023)I arbeidet med å bytte ut organisk fyllmateriale til organisk fyllmateriale i kunstgress grunnet dets miljøfare, oppstår det en ny utfordring, muligheten for økt bakterievekst. Dette kan føre til vekst av indikatororganismer ... -
Microbiologically induced calcite precipitation as a method for ground improvement in granular and cohesive soils
(Master thesis, 2021)Indusert mikrobiologisk utfelling av kalsiumkarbonat (MICP) har potensiale til å bli en alternativ og mer bære-kraftig metode for grunnforsterkning som kan redusere bruken av sementbaserte bindemidler, er mindre for-styrrende ... -
Microbiome “Inception”: an Intestinal Cestode Shapes a Hierarchy of Microbial Communities Nested within the Host

Microcalorimetry on Cu-MCM-22 Reveals Structure-Activity Relationships for the Methane-to-Methanol Reaction
(Peer reviewed; Journal article, 2023)With a stepwise mechanism for direct methane activation to methanol (MTM) over Cu-zeolites, it is possible to produce methanol with high selectivity. With this study, we apply adsorption/desorption experiments with ... -
Microcalorimetry Study of the Adsorption of Asphaltenes and Asphaltene Model Compounds at the Liquid–Solid Surface
(Journal article; Peer reviewed, 2016)The adsorption of an acidic polyaromatic asphaltene model compound (C5PeC11) and indigenous C6-asphaltenes onto the liquid–solid surface is studied. Model compound C5PeC11 exhibits a similar type of adsorption with a plateau ... -
Microchannel Membrane Reactor for production of pure Hydrogen - Inhibition effects on thin self-supported Pd/Ag membranes
