Confocal microscopic FISH image. Simultaneous in situ hybridization with CY5-labeled probe NSV443 and CY3-labeled probe NSR1156. Cells of Nitrosospira spp. are shown in blue; cells of Nitrospira-like bacteria are red. - Source:7
Aerobic, lithoautotrophic, ammonia oxidizers. Play only a minor role in treatment plants 3 2. Can grow mixotrophically, but not heterotrophically 8 9. Urea and potentially hydrogen may serve as alternate electron donors 8 5.
The Nitrosospira are considered K-strategists, with a high substrate affinity and low growth rate 1. They are better suited to a lower concentration of ammonia than is found in treatment plants where they are likely outcompeted by the Nitrosomonas 2. The are sometimes detected in nitrifying bioreactors 10.
