UTILIZATION OF THERMOPHYLIC METHANOGENIC MICROORGANISMS’ ASSOCIATION FOR POULTRY DUNG FERMENTATION

Biogas production process' kinetics of farm's poultry dung (FPD) in thermophylic conditions has been studied. Total gas volume for 29 days of fermentation in control variant did not exceed 84.5 L, while with addition of 10 % and 20 % of balanced thermophylic methanogenic microorganisms association's (BTMMA) inoculate into FPD was 1.7 and 2.1 times higher and amounted to 151 L and 179 L, respectively. It was established that in trial samples maximal methane formation during fermentation process reached 69.7 and 64.7 %, respectively. It was found that in thermophylic fermentation system no bacteria belonging to the Enterobacteriacea family and other pathogens have been detected.
