    • Batch Experiments Demonstrating a Two-Stage Bacterial Process Coupling Methanotrophic and Heterotrophic Bacteria for 1-Alkene Production From Methane 

      Khanongnuch, Ramita; Mangayil, Rahul; Santala, Ville; Hestnes, Anne Grethe; Svenning, Mette Marianne; Rissanen, Antti J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-19)
      Methane (CH<sub>4</sub>) is a sustainable carbon feedstock for value-added chemical production in aerobic CH<sub>4</sub>-oxidizing bacteria (methanotrophs). Under substrate-limited (e.g., oxygen and nitrogen) conditions, CH<sub>4</sub> oxidation results in the production of various short-chain organic acids and platform chemicals. These CH<sub>4</sub>-derived products could be broadened by ...

    • Simultaneous Oxidation of Atmospheric Methane, Carbon Monoxide and Hydrogen for Bacterial Growth 

      Tveit, Alexander Tøsdal; Schmider, Tilman; Hestnes, Anne Grethe; Lindgren, Matteus; Didriksen, Alena; Svenning, Mette Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-12)
      The second largest sink for atmospheric methane (CH<sub>4</sub>) is atmospheric methane oxidizing-bacteria (atmMOB). How atmMOB are able to sustain life on the low CH<sub>4</sub> concentrations in air is unknown. Here, we show that during growth, with air as its only source for energy and carbon, the recently isolated atmospheric methane-oxidizer <i>Methylocapsa gorgona</i> MG08 (USCα) oxidizes three ...

    • Thermal acclimation of methanotrophs from the genus Methylobacter 

      Tveit, Alexander; Söllinger, Andrea; Rainer, Edda Marie; Didriksen, Alena; Hestnes, Anne Grethe; Motleleng, Liabo; Hellinger, Hans-Jörg; Rattei, Thomas; Svenning, Mette Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-18)
      Methanotrophs oxidize most of the methane (CH<sub>4</sub>) produced in natural and anthropogenic ecosystems. Often living close to soil surfaces, these microorganisms must frequently adjust to temperature change. While many environmental studies have addressed temperature effects on CH<sub>4</sub> oxidation and methanotrophic communities, there is little knowledge about the physiological adjustments ...

    • Widespread soil bacterium that oxidizes atmospheric methane 

      Tveit, Alexander Tøsdal; Hestnes, Anne Grethe; Robinson, Serina Lee; Schintlmeister, Arno; Dedysh, Svetlana N; Jehmlich, Nico; Bergen, Martin von; Herbold, Craig; Wagner, Michael; Richter, Andreas; Svenning, Mette Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-08)
      Increasing atmospheric methane concentrations contribute significantly to global warming. The only known biological sink for atmospheric methane is oxidation by methane oxidizing bacteria (MOB). Due to the lack of pure cultures, the physiology and metabolic potential of MOB that oxidize atmospheric methane remains a mystery. Here, we report on isolation and characterization of a MOB that can grow ...
