Diversity and metabolic energy in bacteria
Allen, Ben; Gonzalez-Cabaleiro, Rebeca; Ofiteru, Irina Dana; Øvreås, Lise; Sloan, William T.; Swan, Donna; Curtis, Thomas (Journal article; Peer reviewed, 2023)Why are some groups of bacteria more diverse than others? We hypothesize that the metabolic energy available to a bacterial functional group (a biogeochemical group or ‘guild’) has a role in such a group’s taxonomic ... -
Innovating carbon-capture biotechnologies through ecosystem-inspired solutions
Schweitzer, Hannah; Aalto, Nerea Johanna; Busch, Wolfgang; Chan, Dennis Tin Chat; Chiesa, Matteo; Elvevoll, Edel O.; Gerlach, Robin; Krause, Kirsten; Mocaer, Karel; Moran, James J.; Noel, Joseph P.; Patil, Shalaka Kiran; Schwab, Yannick; Wijffels, Rene Hubertus; Wulff, Angela; Øvreås, Lise; Bernstein, Hans Christopher (Journal article; Peer reviewed, 2021)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 ... -
Mechanisms Generating Dichotomies in the Life Strategies of Heterotrophic Marine Prokaryotes
Thingstad, T. Frede; Øvreås, Lise; Vadstein, Olav (Journal article; Peer reviewed, 2022)Understanding the mechanisms that generate and maintain diversity in marine prokaryotic communities is one of the main challenges for contemporary marine microbiology. We here review how observational, experimental, and ... -
Metagenome-assembled genome distribution and key functionality highlight importance of aerobic metabolism in Svalbard permafrost
Xue, Yaxin; Jonassen, Inge; Øvreås, Lise; Tas, Neslihan (Journal article; Peer reviewed, 2020)Permafrost underlies a large portion of the land in the Northern Hemisphere. It is proposed to be an extreme habitat and home for cold-adaptive microbial communities. Upon thaw permafrost is predicted to exacerbate increasing ... -
A novel moderately thermophilic facultative methylotroph within the class Alphaproteobacteria
Islam, Tajul; Hernández, Marcela; Gessesse, Amare; Colin Murrell, Murrell; Øvreås, Lise (Journal article; Peer reviewed, 2021-02-25)Methylotrophic bacteria (non-methanotrophic methanol oxidizers) consuming reduced carbon compounds containing no carbon–carbon bonds as their sole carbon and energy source have been found in a great variety of environments. ... -
A Novel Moderately Thermophilic Type Ib Methanotroph Isolated from an Alkaline Thermal Spring in the Ethiopian Rift Valley
Islam, Tajul; Gessesse, Amare; Garcia-Moyano, Antonio; Murrell, J. Colin; Øvreås, Lise (Journal article; Peer reviewed, 2020-02-13)Aerobic moderately thermophilic and thermophilic methane-oxidizing bacteria make a substantial contribution in the control of global warming through biological reduction of methane emissions and have a unique capability ... -
Planctomycetes as a Vital Constituent of the Microbial Communities Inhabiting Different Layers of the Meromictic Lake Sælenvannet (Norway)
Storesund, Julia Endresen; Lanzén, Anders; Nordmann, Eva-Lena; Rief Armo, Hilde; Lage, Olga M.; Øvreås, Lise (Journal article; Peer reviewed, 2020)Meromictic lakes are permanently stratified lakes that display steep gradients in salinity, oxygen and sulphur compounds tightly linked to bacterial community structure and diversity. Lake Sælenvannet is a meromictic lake ... -
Sewage-based surveillance shows presence of Klebsiella pneumoniae resistant against last resort antibiotics in the population in Bergen, Norway
Radisic, Vera; Grevskott, Didrik Hjertaker; Lunestad, Bjørn Tore; Øvreås, Lise; Marathe, Nachiket (Journal article; Peer reviewed, 2022)The aim of this study was to understand the prevalence of antibiotic resistance in Klebsiella pneumoniae present in the population in Bergen city, Norway using city-scale sewage-based surveillance, as well as the potential ... -
The summer bacterial and archaeal community composition of the northern Barents Sea
Thiele, Stefan; Vader, Anna; Thomson, Stuart; Saubrekka, Karoline; Petelenz-Kurdziel, Elzbieta Anna; Rief Armo, Hilde; Müller, Oliver; Olsen, Lasse Mork; Bratbak, Gunnar; Øvreås, Lise (Journal article; Peer reviewed, 2023)Climate change related alterations in the Arctic have influences on the marine ecosystems, in particular on phytoplankton bloom dynamics. Since phytoplankton blooms are the main provider of carbon sources to the microbial ... -
A winter-to-summer transition of bacterial and archaeal communities in Arctic sea ice
Thiele, Stefan; Storesund, Julia Endresen; Férnandez-Méndez, Mar; Assmy, Philipp; Øvreås, Lise (Journal article; Peer reviewed, 2022-08-15)The Arctic is warming 2–3 times faster than the global average, leading to a decrease in Arctic sea ice extent, thickness, and associated changes in sea ice structure. These changes impact sea ice habitat properties and ...
