Abstract
Peatlands are major sources of the greenhouse gas methane (CH4), yet in many peatlands, CO2 production from unresolved anaerobic processes exceeds CH4 production. Anaerobic degradation produces the precursors of CH4 production but also represents competing processes. We show that anaerobic degradation leading to high or low CH4 production involved distinct sets of bacteria. Well-known fermenters dominated in a peatland with high CH4 production, while novel and unconventional degraders could be identified in a site where CO2 production greatly exceeds CH4 production. Our results help identify and assign functions to uncharacterized bacteria that promote or inhibit CH4 production and reveal bacteria potentially producing the excess CO2 in acidic peat. This study contributes to understanding the microbiological basis for different levels of CH4 emission from peatlands.
