Abstract:
This study investigates the kinetic parameters of biogas formation during the thermophilic anaerobic digestion of farm poultry dung (FPD). In the control variant, the cumulative biogas output recorded over a 29-day fermentation period was limited to 84.5 L. Supplementation of the substrate with 10% and 20% balanced thermophilic methanogenic microbial association (BTMMA) significantly intensified methanogenesis, increasing total gas production to 151 L and 179 L, respectively corresponding to 1.7-fold and 2.1-fold enhancements compared to the control. Analysis of gas composition revealed that the treated variants achieved maximum methane concentrations of 69.7% and 64.7%, indicating a stable and efficient methanogenic activity throughout the process. Furthermore, microbiological assessment demonstrated that thermophilic fermentation effectively suppressed sanitary-indicator microorganisms, with no detectable members of the Enterobacteriaceae family or other pathogenic taxa. These findings highlight the potential of BTMMA-supplemented thermophilic digestion as a reliable and safe method for converting poultry manure into high quality biogas.
