Methanogenesis in biogas reactors under inhibitory ammonia concentration requires community-wide tolerance.

ABSTRACT: Ammonia (NH₃) inhibition represents a major limitation to methane production during anaerobic digestion of organic material in biogas reactors. This process relies on co-operative metabolic interactions between diverse taxa at the community-scale. Despite this, most investigations have focused singularly on how methanogenic Archaea respond to NH₃ stress. With a high-NH₃ pre-adapted and un-adapted community, this study investigated responses to NH₃ inhibition both at the community-scale and down to individual taxa. The pre-adapted community performed methanogenesis under inhibitory NH₃ concentrations better than the un-adapted. While many functionally important phyla were shared between the two communities, only taxa from the pre-adapte
