Adaptation of anaerobic ammonium oxidizing (anammox) bacteria to salinity in a continuous reactor.
Rønning, Are Johan (Master thesis, 2013)The anaerobic ammonium oxidation (anammox) process is the most recent discovery in the nitrogen cycle on Earth. The anammox process is a microbial process where ammonium (NH4+) is anaerobically oxidized to gaseous nitrogen. ... -
Assessment of biomass functionalities in a biofilm membrane bioreactor (BF-MBR) targeting biological nutrient removal
Kjørlaug, Oda Marie (Master thesis, 2013)High concentrations of nutrients such as nitrogen, phosphorus and organicmatter can cause serious eutrophication in receiving water bodies. In biologicalwastewater treatment microorganisms remove nutrients from thewastewater ... -
Butanolfermentering i en co-kultur: Effekt av inhibitorer dannet under forbehandling av tare
Debech, Nadia (Master thesis, 2013)Okende energibehov samt økt klimatrussel, har gjort at forskning på fornybar energi fått mye oppmerksomhet verden over. Bioenergi produsert ved utnyttelse av biomasse, er et viktig alternativ for erstatning av petroleumsbasert ... -
Effect of salinity shifts on microbial community composition in different nitrifying biofilms in continuous moving bed biofilm reactors.
Jonassen, Kjell Rune (Master thesis, 2013)Salinity is considered a common stress factor when nitrification is applied in waste water treatment. Observations often show a sub-optimal nitrification performance as a response to variations in in-fluent salinity. ... -
Temperature Effects on Biodegradation of Dispersed Crude Oil: Degradation Rates and Microbial Communities Associated with Degradation of Oil Droplets
Lofthus, Synnøve (Master thesis, 2014)Depending on the weather- and sea conditions, oil spilled at sea may disperse into the water column. Dispersion of oil promotes biodegradation of oil hydrocarbons (HCs) due to an increased surface-to-volume ratio. In this ...
