Inter-laboratory testing of the effect of DNA blocking reagent G2 on DNA extraction from low-biomass clay samples
Jacobsen, Carsten Suhr; Nielsen, Tue Kjærgaard; Vester, Jan Kjølhede; Stougaard, Peter; Nielsen, Jeppe Lund; Voriskova, Jana; Winding, Anne; Baldrian, Petr; Liu, Binbin; Frostegård, Åsa; Pedersen, Dorthe; Tveit, Alexander Tøsdal; Svenning, Mette Marianne; Tebbe, Christoph C.; Øvreås, Lise; Jakobsen, Pia Bach; Blazewicz, Steven J.; Hubablek, Valerie; Bertilsson, Stefan; Hansen, Lars Hestbjerg; Cary, S. Craig; Holben, William E.; Ekelund, Flemming; Bælum, Jacob (Peer reviewed; Journal article, 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 ... -
Response of Methanogens in Arctic Sediments to Temperature and Methanogenic Substrate Availability
Blake, Lynsay; Tveit, Alexander Tøsdal; Øvreås, Lise; Head, Ian M.; Gray, Neil (Peer reviewed; Journal article, 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 ... -
Targeting methanotrophs and isolation of a novel psychrophilic Methylobacter species from a terrestrial Arctic alkaline methane seep in Lagoon Pingo, Central Spitsbergen (78° N)
Patil, Shalaka Kiran; Islam, Tajul; Tveit, Alexander Tøsdal; Hodson, Andrew; Øvreås, Lise (Journal article; Peer reviewed, 2024)The microbial diversity associated with terrestrial groundwater seepage through permafrost soils is tightly coupled to the geochemistry of these fluids. Terrestrial alkaline methane seeps from Lagoon Pingo, Central Spitsbergen ...
