Unusual Plastoquinones in Non-Phototrophic Nitrifying Bacteria. [PDF]
Environ Microbiol RepChemolithoautotrophic nitrifying bacteria of the genus Nitrospira exclusively possess unusual methyl‐plastoquinones with a standard redox potential below that of canonical plastoquinone and ubiquinone, suggesting functional roles in bidirectional electron transport.

Metagenomic Evidence for the Presence of Comammox
mSphere, 2016 We report metagenomic evidence for the presence of a Nitrospira-like organism with the metabolic potential to perform the complete oxidation of ammonia to nitrate (i.e., it is a complete ammonia oxidizer [comammox]) in a drinking water system.
