Nitrospira make up the key nitrite-oxidizing bacteria in most wastewater treatment systems. While a lot of the literature highlights Nitrobacter, Nitrospira generally grow best on (very) low levels of nitrite found in WWTPs. Nitrobacter, on the other hand, likes higher nitrite concentrations and is easier to grow in the lab.
- Some strains can use nitrate as a terminal electron acceptor
