Electrode-associated growth of ANME-2d
Anaerobic methanotrophic archaea mitigate methane emissions in anoxic environments as key members of the biological methane filter. Despite their ecological significance, physiology of anaerobic methanotrophs remains poorly understood. Here, we show that cultivation on poised electrodes yields near-axenic cultures of freshwater anaerobic methanotrophic archaea previously cultivated on nitrate. This study contains both short- and long-read metagenomic datasets of different bioelectrochemical systems and used inoculum (long-term bioreactor cultivation).
