ABSTRACT

The subject of investigations was the evaluation of sanitary-hygienic state of slurry subject to anaerobic fermentation in bioreactor under thermophilic conditions. The influence of anaerobic fermentation on the survival of Salmonella senftenberg, EHEC and streptococci D group was specified. It turned out from investigations that after 4 hours the number of Salmonella senftenberg and EHEC bacteria decreased 10⁸ times in relation to the control test. The lowest elimination rate was for streptococci D group. The percentage of invasive eggs of Ascaris suum decreased after 4 hours from 89% to 7%. The investigation proved proper run of anaerobic process in bioreactor and sufficient desinfection of cattle slurry.

Key words: cattle slurry, anaerobic fermentation, parasite bacteria.
