    Research output: Contribution to journalJournal articleResearchpeer-review


    Survival of Aujeszky's disease virus in pig slurry was investigated during anaerobic storage at 5, 20, 35, 40, 45, 50 and 55°C using 100-ml laboratory models simulating the conditions in slurry tanks during winter and summer seasons and during anaerobic digestion in batch reactors. The inactivation rate was found to increase with increasing temperature. Virus was inactivated at 5 and 20°C in 15 weeks and 2 weeks, respectively. At 35°C (mesophilic conditions) the virus was inactivated in 5 hours and at 55°C (thermophilic conditions) no virus could be detected after 10 minutes.
