Biofilms remember: Osmotic stress priming as a microbial management strategy for improving salinity acclimation in nitrifying biofilms
Navada, Sharada; Vadstein, Olav; Gaumet, Frederic; Tveten, Ann-Kristin; Spanu, Claudia; Mikkelsen, Øyvind; Kolarevic, Jelena (Peer reviewed; Journal article, 2020)With increasing freshwater scarcity and greater use of seawater,fluctuating salinities are becomingcommon in water treatment systems. This can be challenging for salinity-sensitive processes like nitri-fication, especially ... -
The Development of Polydimethysiloxane/ZnO–GO Antifouling Coatings
Zhang, Xiaoxue; Årstøl, Erland; Nymark, Marianne; Fages-Lartaud, Maxime René; Mikkelsen, Øyvind (Peer reviewed; Journal article, 2021)The development of antifouling coating for sensor is desirable because the biofilm can shorten sensor’s life and cause inaccurate reading. In this study, a facile one-pot reaction was used to synthesized ZnO–graphene oxide ... -
Effekten av nanofiltrert innløpsvann på svovelkonsentrasjon og vannkvalitetparametere i resirkulerende akvakultursystemer
Larsen, Vilde Marie (Master thesis, 2021)Atlanterhavslaks (Salmo salar) er den største fiskearten som produseres i akvakulturnæringen, og representerer 93,39% av Norges totale fiskeproduksjon. Utvidelse av akvakulturdrift har i løpet av de siste årene vært ... -
Influence of rate of salinity increase on nitrifying biofilms
Navada, Sharada; Vadstein, Olav; Tveten, Ann-Kristin; Verstege, Gerhardus C.; Terjesen, Bendik Fyhn; Mota, Vasco C.; Venkataraman, Vishwesh; Gaumet, Frederic; Mikkelsen, Øyvind; Kamstra, Andries (Journal article; Peer reviewed, 2019)A strategy for rapid increase in salinity with minimal impact on nitrification is important for ammonia removal from saline effluents, especially in recirculating aquaculture systems with high water reuse. To study the ... -
A salty start: Brackish water start-up as a microbial management strategy for nitrifying bioreactors with variable salinity
Navada, Sharada; Sebastianpillai, Marianna; Kolarevic, Jelena; Fossmark, Ragnhild Olsen; Tveten, Ann-Kristin; Gaumet, Frederic; Mikkelsen, Øyvind; Vadstein, Olav (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 ...
