A combination analysis of SIP and in situ microbiological methods was applied on the anaerobic digestion of biomass organics suffering from severe acids inhibition. The studies found that accumulated acids were degraded mainly by Methanosarcina firstly with acetoclastic pathway and then with hydrogenotrophic pathway under mesophilic condition, whereas acids were mainly degraded to methane by the tandem reactions of syntrophic acetate oxidation and hydrogenotrophic methanogenesis under thermophilic condition.
