Among ammonia-oxidizing bacteria, Nitrosomonas eutropha-like microbes are distributed in strongly eutrophic environments such as wastewater treatment plants and animal manure. In the present study, we isolated an ammonia-oxidizing bacterium tolerant of high ammonium levels, designated strain KYUHI-S-T, from composted cattle manure. Unlike the other known Nitrosomonas species, this isolate grew at 1,000 mM ammonium. Phylogenetic analyses based on 16S rRNA and amoA genes indicated that the isolate belonged to the genus Nitrosomonas and formed a unique cluster with the uncultured ammonia oxidizers found in wastewater systems and animal manure composts, suggesting that these ammonia oxidizers contributed to removing higher concentrations of ammonia in strongly eutrophic environments. Based on the physiological and phylogenetic data presented here, we propose and call for the validation of the provisional taxonomic assignment Nitrosomonas stercoris, with strain KYUHI-S as the type strain (type strain KYUHI-S-T = NBRC 110753(T) = ATCC BAA-2718(T)).
