Metal Oxide Reduction Linked to Anaerobic Methane Oxidation

Oluwatobi E Oni et al. Trends Microbiol. 2017 Feb.

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.

Keywords: ANME; ANME-2d; AOM-associated archaea (AAA); anaerobic oxidation of methane; extracellular electron transfer; iron reduction.
