Distinct Microbial Communities Within and On Seep Carbonates Support Long-term Anaerobic Oxidation of Methane and Novel pMMO Diversity

by Keith Cowing

At methane seeps worldwide, syntrophic anaerobic methane-oxidizing archaea and sulfate-reducing bacteria (ANME-SRB) promote carbonate precipitation and rock formation, acting as methane and carbon sink.
