Results from a french inter‐laboratory campaign on the biological methane potential of solid substrates

International audience; Every year the knowledge about the microbial ecology of anaerobic digestion increases but despite that, the inoculation step of anaerobic digesters still remains empirical. Anaerobic digestion remains a microbial process without any microbial engineering. In this review we try to understand why putting in practice this knowledge remains difficult by identifying bottlenecks of this unsuccessful story.
