Discovery of New Nitrite-Oxidizing Bacteria Increases Phylogenetic and Metabolic Diversity within This Niche

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-oxidizi...
