Methanotrophic bacteria may consume 60 to 90% of methane (CH4) produced in thawing permafrost peatlands. Rates of aerobic methanotrophy are dependent on the availability of CH4, redox conditions driven by O2 availability, and methanotroph community composition. This study investigated potential CH4...
