title: Metal Oxide Reduction Linked to Anaerobic Methane Oxidation.
abstract: Microbial methanotrophy is important in mitigating methane emissions to the atmosphere. Geochemical evidence suggests the occurrence of anaerobic methane oxidation with metal oxides in natural environments. A study has now identified, for the first time, novel freshwater archaea of the order Methanosarcinales that can oxidize methane with Fe(III) and Mn(IV) minerals as electron acceptors.
