Anaerobic oxidation of methane associated with sulfate reduction in a natural freshwater gas source [PDF]
The occurrence of anaerobic oxidation of methane (AOM) and trace methane oxidation (TMO) was investigated in a freshwater natural gas source. Sediment samples were taken and analyzed for potential electron acceptors coupled to AOM.

The Apparent Involvement of ANMEs in Mineral Dependent Methane Oxidation, as an Analog for Possible Martian Methanotrophy [PDF]
On Earth, marine anaerobic methane oxidation (AOM) can be driven by the microbial reduction of sulfate, iron, and manganese. Here, we have further characterized marine sediment incubations to determine if the mineral dependent methane oxidation ...

Cryptic Carbon Cycle at Methane‐Seeps of the South China Sea: Evidence From Porewaters
Abstract Anaerobic oxidation of methane (AOM) governs methane consumption at seeps, yet δ13C‐CH4 values in the sulfate‐methane transitions are commonly lower than predicted from preferential 12C utilization by methanotrophic archaea, suggesting the influence of a different methane source. To address this isotope discrepancy, we used high‐resolution ion

Anaerobic oxidation of methane in hypersaline cold seep sediments [PDF]
Life in hypersaline environments is typically limited by bioenergetic constraints. Microbial activity at the thermodynamic edge, such as the anaerobic oxidation of methane (AOM) coupled to sulphate reduction (SR), is thus unlikely to thrive in these ...
