In anaerobic digestion the degradation of proteins in the feedstock result in the formation of ammonia which stays in equilibrium with ammonium. Small quantities of ammonia contribute to the feedstock buffer capacity. Ammonia beyond a certain limit can be inhibitory to microbes in anaerobic digestion.
