  1. 1. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Aubree Stephens; [2023]
    Nyckelord :methanogen; archaea; hydrogenotroph; halotolerant; Methanobacterium; Chimaera seep; methanogenesis;

    Sammanfattning : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. LÄS MER

  3. 2. Isolation and cultivation of methanogenic archaea from serpentinization system at Chimaera Seeps, Turkey

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Bobby Zetterlind; [2020]
    Nyckelord :Archaea; methanogens; Chimaera seeps; serpentinization system; isolation; cultivation;

    Sammanfattning : A methanogenic archaeon was successfully isolated from iron-rich environmental samples from the Chimaera seeps in Turkey by cultivation in anoxic media supplemented with H2/CO2 and an antibiotic, namely erythromycin. The morphological features of this methanogen were non-motile rod cells approximately 1.7 – 8.5 μm in length and 0. LÄS MER

  4. 3. The gut microbiota and its relationship with obese children

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Isabella Aryee; [2019]
    Nyckelord :childhood obesity; gut microbiota; methanogens; Methanobacteriales;

    Sammanfattning : Background: It’s decelerated that childhood obesity is a global epidemic since 21st century. General obesity has doubled since 1980 and comes with a distinct increase of mobility and mortality. LÄS MER

  5. 4. Metanogenreduktion : en hållbar lösning på växthuseffekten?

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Karin Tufvesson; [2019]
    Nyckelord :metanogener; metan; våmflora; metanreducerande strategier; djurvälfärd;

    Sammanfattning : Allt fler blir medvetna om vikten av hållbar utveckling och klimatpåverkan. Metan, en potent växthusgas som bidrar till en ökad växthuseffekt är ofta i fokus. Inte sällan får idisslare bära den största skulden för det människoorsakade metanutsläppet. I idisslares våm finns nämligen mikroorganismer, metanogener, som bildar metan. LÄS MER

  7. 5. Comparison of anaerobic sludge granules from different wastewater plants with respect to granule size, substrate degradation and methanogenic community

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Jonathan Andrén; [2018]
    Nyckelord :anaerobic digestion; granule; UASB; EGSB; VFA; methanogen; acetoclastic; hydrogenotrophic; acetogenic; mcrA; ; T-RFLP; methanosarcina; methanosaeta;

    Sammanfattning : Within the objective to replace fossil fuel with sustainable sources there is a growing pressure to advance such development. Anaerobic digestion (AD) is beneficial not only as a waste management technology, but also to recycle organic waste into methane which can be used for heating, production of electricity or vehicle fuel.
