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.
微生物甲烷营养作用对于减少甲烷向大气中的排放非常重要。地球化学证据表明,在自然环境中,金属氧化物会发生厌氧甲烷氧化作用。目前的一项研究首次发现,新型淡水古菌 Methanosarcinales 可以利用 Fe(III) 和 Mn(IV) 矿物作为电子受体氧化甲烷。
