Ammonia-oxidizing archaea have similar power requirements in diverse marine oxic sediments
Zhao, Rui; Mogollon, Jose M; Roerdink, Desiree Lisette; Thorseth, Ingunn Hindenes; Økland, Ingeborg Elisabet; Jørgensen, Steffen Leth (Journal article; Peer reviewed, 2021)Energy/power availability is regarded as one of the ultimate controlling factors of microbial abundance in the deep biosphere, where fewer cells are found in habitats of lower energy availability. A critical assumption ... -
A late Paleoproterozoic (1.74 Ga) deep-sea, low-temperature, iron-oxidizing microbial hydrothermal vent community from Arizona, USA
Little, Crispin T.S.; Johannessen, Karen Cecilie; Bengtson, Stefan; Chan, Clara S.; Ivarsson, M.; Slack, John F.; Broman, Curt; Thorseth, Ingunn Hindenes; Grenne, Tor; Rouxel, Olivier J.; Bekker, Andrey (Journal article; Peer reviewed, 2021)Modern marine hydrothermal vents occur in a wide variety of tectonic settings and are characterized by seafloor emission of fluids rich in dissolved chemicals and rapid mineral precipitation. Some hydrothermal systems vent ... -
Mapping Microbial Abundance and Prevalence to Changing Oxygen Concentration in Deep-Sea Sediments Using Machine Learning and Differential Abundance
Møller, Tor Einar; Moine-Bauer, Sven Le; Hannisdal, Bjarte; Zhao, Rui; Baumberger, Tamara; Roerdink, Desiree Lisette; Dupuis, Amandine; Thorseth, Ingunn Hindenes; Pedersen, Rolf B.; Jørgensen, Steffen Leth (Journal article; Peer reviewed, 2022)Oxygen constitutes one of the strongest factors explaining microbial taxonomic variability in deep-sea sediments. However, deep-sea microbiome studies often lack the spatial resolution to study the oxygen gradient and ... -
On the biogenicity of Fe-oxyhydroxide filaments in silicified low-temperature hydrothermal deposits: Implications for the identification of Fe-oxidizing bacteria in the rock record
Johannessen, Karen Cecilie; McLoughlin, Nicola; Vullum, Per Erik; Thorseth, Ingunn Hindenes (Peer reviewed; Journal article, 2020)Microaerophilic Fe(II)‐oxidizing bacteria produce biomineralized twisted and branched stalks, which are promising biosignatures of microbial Fe oxidation in ancient jaspers and iron formations. Extracellular Fe stalks ... -
The role of authigenic sulfides in immobilization of potentially toxic metals in the Bagno Bory wetland, southern Poland
Smieja-Król, Beata; Janeczek, Janusz; Bauerek, Arkadiusz; Thorseth, Ingunn Hindenes (Peer reviewed; Journal article, 2015-10)The supply of Cd, Cu, Fe, Pb, Zn, and Tl into a wetland in the industrial area of Upper Silesia, southern Poland via atmospheric precipitation and dust deposition has been counterbalanced by the biogenic metal sulfide ...
