Biodegradation of Dispersed Oil in natural Seawaters from Western Greenland and a Norwegian fjord
Brakstad, Odd Gunnar; Davies, Emlyn John; Ribicic, Deni; Winkler, Anika; Brönner, Ute; Netzer, Roman (Journal article; Peer reviewed, 2018)With increasing oil exploration, production and transportation in the Arctic, predictions of the fate of spilled oil become important, including oil compound biodegradation. The use of chemical dispersants may result in ... -
Comparison of microbial community dynamics induced by distinct crude oil dispersions reveals compositional differences
Ribicic, Deni; Netzer, Roman; Winkler, Anika; Brakstad, Odd Gunnar (Journal article; Peer reviewed, 2018)To understand the impact of oil contamination on marine microbial communities, numerous studies have been conducted following microbial dynamics after oil spills and concerning the effects of different environmental ... -
Dispersibility and biotransformation of oils with different properties in seawater
Brakstad, Odd Gunnar; Farooq, Umer; Ribicic, Deni; Netzer, Roman (Journal article; Peer reviewed, 2018)Dispersants are used to remove oils slicks from sea surfaces and to generate small oil-droplet dispersions, which may result in enhanced biodegradation of the oil. In this study, dispersibility and biodegradation of ... -
Microbial communities in seawater from an Arctic and a temperate Norwegian fjord and their potentials for biodegradation of chemically dispersed oil at low seawater temperatures
Ribicic, Deni; Netzer, Roman; Winkler, Anika; Brakstad, Odd Gunnar (Journal article; Peer reviewed, 2018)Biodegradation of chemically dispersed oil at low temperature (0–2 °C) was compared in natural seawater from Arctic (Svalbard) and a temperate (Norway) fjords. The oil was premixed with a dispersant (Corexit 9500) and ... -
Microbial community and metagenome dynamics during biodegradation of dispersed oil reveals potential key-players in cold Norwegian seawater
Ribicic, Deni; Netzer, Roman; Hazen, Terry C.; Techtmann, Stephen M.; Drabløs, Finn; Brakstad, Odd Gunnar (Journal article; Peer reviewed, 2018)Oil biodegradation as a weathering process has been extensively investigated over the years, especially after the Deepwater Horizon blowout. In this study, we performed microcosm experiments at 5 °C with chemically dispersed ... -
Oil type and temperature dependent biodegradation dynamics. Combining chemical and microbial community data through multivariate analysis
Ribicic, Deni; McFarlin, Kelly Marie; Netzer, Roman; Brakstad, Odd Gunnar; Winkler, Anika; Throne-Holst, Mimmi; Størseth, Trond Røvik (Journal article; Peer reviewed, 2018)Background This study investigates a comparative multivariate approach for studying the biodegradation of chemically dispersed oil. The rationale for this approach lies in the inherent complexity of the data and challenges ...
