| description | ABSTRACT K. Kitzinger et al. (mBio 9:e01186-18, 2018, https://doi.org/10.1128/mBio.01186-18) report the first isolation of a novel nitrite-oxidizing bacterium, “Candidatus Nitrotoga,” and provide the first detailed information on the physiology, phylogeny, and characterization of the nitrite-oxidizing system of this genus. The isolate was derived from a wastewater treatment system and exhibits adaptation and tolerance to relatively high levels of nitrite. The origin of its nitrite oxidoreductase is distinct from other known nitrite oxidoreductase (NXR) systems, having arisen either in this organism or by horizontal gene transfer. In contrast to many earlier-characterized nitrite oxidizers, it displays substantial metabolic plasticity in its mode of energetic metabolism with capabilities to use both hydrogen and sulfite as electron donors. |
