The anaerobic bioconversion of biomass to methane via anaerobic biodigestion requires a multi-step biological process, including microorganisms with distinct roles. Here, the dynamics of acidogenic bacterial populations by classical microbiology, as well as biogas productivity by gasometer and chromatography, in the anaerobic co-digestion process were studied. This paper presents a performance evaluation of co-digestion systems for biogas production using cattle manure and wastes from the Sewage Treatment Station of a brewery and ricotta cheese whey. The search revealed that the type of substrate added in co-digestion with cattle manure, Carbon/Nitrogen ratio, and Ammonia Nitrogen were the most influential factors that explained many of the variations of the microbiota in the biodigesters fed. This study demonstrated a good potential for the use of ricotta cheese whey in the production of biogas and its further conversion into energy. These findings could provide some fundamental and technical information for the co-treatment of industrial derived wastes in centralized anaerobic biodigestion facilities in a sustainable manner with high process capacity and methane recovery.  aBiogás  aEsterco  aGado  aGado Leiteiro  aMetano  aCo-digestão anaeróbica1 aBARROS, N. de O.1 aSANTANA, L.
