WebbHowever, if present at high concentrations, ammonia is inhibitory to methanogenesis (McCarty, 1964; Gallert et al., 1998). In aqueous conditions, ammonia exists mainly in two forms, as the ionised ammonium ion (NH. 4+) stable in the aqueous phase, and in gaseous form as free ammonia (FAN), as shown in Eq. Webb18 maj 2009 · The results taken as a whole suggest that NO 3 − inhibition of methanogenesis is low to moderate whereas the inhibition caused by NO 2 − is very severe. The objective of this study is to determine how toxic NO − x compounds are in mixed microbial consortia found in anaerobic bioreactors.
