Insights into Ammonia Adaptation and Methanogenic Precursor Oxidation by Genome-Centric Analysis.

ABSTRACT: Ammonia released from the degradation of protein and/or urea usually leads to suboptimal anaerobic digestion (AD) when N-rich organic waste is used. However, the insights behind the differential ammonia tolerance of anaerobic microbiomes remain an enigma. In this study, the cultivation in synthetic medium with different carbon sources (acetate, methanol, formate, and H₂/CO₂) shaped a common initial inoculum into four unique ammonia-tolerant syntrophic populations. Specifically, various levels of ammonia tolerance were observed: consortia fed with methanol and H₂/CO₂ could grow at ammonia levels up to 7.25 g NH⁺-N/L, whereas the other two groups (formate and acetate) only thrived at 5.25 and 4.25 g NH⁺-N/L, respectively.
