Pathogen decay or growth in anaerobic digesters: a question with no possible answer? Elements of understanding for non-microbiologists

Abstract : The goal of this contribution is to analyze the relevance of measuring anaerobic digestion effectiveness to the elimination of pathogens. Elements such as the variation in abiotic and biotic conditions, indicators and measurement tools are analyzed in light of experimental data. We conclude that measuring the effectiveness of anaerobic digesters in eliminating pathogens seems an unrealistic challenge. We recommend measuring the pathogen risk only though analyzing the presence of pathogens in the digestate, and not via the decontamination efficiency of the process.
