Relative abundance of methanogenesis-related genes shown as a percentage of total functional annotations of SEED subsystems analyzed by MG-RAST server. fmd—formylmethanofuran dehydrogenase (subunits ABCDEFGH); ftr—formylmethanofuran-H4MPT formyltransferase; mch—methenyl-H4MPT cyclohydrolase; mtd—methylene-5,6,7,8-H4MPT dehydrogenase; hmd—H2-forming N5,N10-methylene-H4MPT dehydrogenase; mer—5,10-methylene-H4MPT reductase; mtr—H4MPT-methyltransferase (subunits ABCDEFGHX); ack—acetate kinase; pta—phosphate acetyltransferase; acs—acetyl-CoA synthetase; cdh—CO dehydrogenase/acetyl-CoA synthase; mta—methanol-specific methyltransferase complex (subunits ABC); mtb—methylamine-specific methyltransferase complex (including subunits ABC for mono- di- and tri-methylamines utilization); mcr—methyl CoM reductase (subunits ABG); hdr—CoB-CoM heterodisulfide reductase (subunits ABCDE); H4MPT—tetrahydromethanopterin; CoA—coenzyme A; CoB—coenzyme B; CoM—coenzyme M. Genes involved in the given pathway, hydrogenotrophic (CO2), acetoclastic (CH3COOH) and methylotrophic (CH3OH and (CH3)xNH), were marked by frame. Genes common for all pathways were left without a frame. ABF—agricultural biogas plant fermenter; ABF_TS—laboratory reactor inoculated with agricultural biogas plant fermenter sample; ABH—agricultural biogas plant hydrolyzer; CS—cattle slurry; CM—cattle manure; GM—gold mine; LB—lowland bog; WTP—wastewater treatment plant; WTP_TS—laboratory reactor inoculated with wastewater treatment plant sample
