  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
