The effect of methanogenesis on the survival of model bacterial strains (Escherichia coli EC 5, Staphylococcus aureus SA 11, Enterococcus faecium CCM 4231) and non-embryonated helminth eggs (Ascaris suum) was investigated in pig slurry. Two pilot-plant experiments were carried out in two anaerobic digesters (800 and 1 000 litre) in a mesophilic thermal range (35-37 degrees C). The mean hydraulic retention time of the digesters was 20 days. The methanogenesis process was monitored by determining the following chemical parameters: pH, N-NH3, total dry matter (kg/day)
