ABSTRACT: Swine intensive production increases the necessity of efficient manure management and treatment. Additionally, animal carcasses disposal inside or outside animal rearing farms is under concern and object of discussion because biosecurity protocols. Anaerobic digestion has a potential to convert biodegradable organic carbon into biogas. Swine manure and swine carcass co-digestion could be a feasible alternative to treat these residues and generate a renovable energy source. However, biodigestion has limited capacity to remove pathogenic micro-organisms and this must be studied to minimize the biologic risks and assure safe disposal and use of digestate. Considering this, the objective of this study was to evaluate the Escherichia coli (E. coli) and Salmonella enterica ? serovar Senftenberg (S. Senftenberg) inactivation kinetics during swine manure and swine carcass co-digestion. The inactivation experiments were conducted in triplicates, where different inactivation strategies were performed at two temperatures (24ºC and 37ºC).Two swine carcass/swine manure ratios were studied(3kgcarcass.m-3 manureand 15 kgcarcass.m-3 manure). S. Senftenberg was total inactivated after 10 days for both temperature and both ratios of swine carcass/swine manure. At 37ºC and ratio of 3kgcarcass.m-3 manureE.coli was total inactivated after 10 days and at ratio 15 kgcarcass.m-3 manureafter 8 days. At 24ºC it were necessary 25 days and 31 days for relations 15kg.m-3 and 3kg.m-3 respectively. Digestion temperature influenced the inactivation process being more pronounced for E. coli. In batch reactors operating at 37ºC it is suggested hydraulic retention time (HRT) greater than 10 days for total elimination of E.coli and S. Senftenberg, while at 24ºC for at least 30 days.
