Changes in marine prokaryote composition with season and depth over an Arctic polar year
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-13)As the global climate changes, the higher latitudes are seen to be warming significantly faster. It is likely that the Arctic biome will experience considerable shifts in ice melt season length, leading to changes in photoirradiance and in the freshwater inputs to the marine environment. The exchange of nutrients between Arctic surface and deep waters and their cycling throughout the water column ... -
Innovating carbon-capture biotechnologies through ecosystem-inspired solutions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-22)Rising atmospheric carbon concentrations affect global health, the economy, and overall quality of life. We are fast approaching climate tipping points that must be addressed, not only by reducing emissions but also through new innovation and action toward carbon capture for sequestration and utilization (CCSU). In this perspective, we delineate next-generation biotechnologies for CCSU supported by ... -

Inter-laboratory testing of the effect of DNA blocking reagent G2 on DNA extraction from low-biomass clay samples
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-09)Here we show that a commercial blocking reagent (G2) based on modified eukaryotic DNA significantly improved DNA extraction efficiency. We subjected G2 to an inter-laboratory testing, where DNA was extracted from the same clay subsoil using the same batch of kits. The inter-laboratory extraction campaign revealed large variation among the participating laboratories, but the reagent increased the ... -
Response of Methanogens in Arctic Sediments to Temperature and Methanogenic Substrate Availability
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-17)Although cold environments are major contributors to global biogeochemical cycles, comparatively little is known about their microbial community function, structure, and limits of activity. In this study a microcosm based approach was used to investigate the effects of temperature, and methanogenic substrate amendment, (acetate, methanol and H2/CO2) on methanogen activity and methanogen community ...
