However, denitrifying organisms possess two types of functionally equivalent nitrite reductases, which are considered mutually exclusive to a single denitrifier, i.e., both reductases will not occur within one denitrifier.
Analysis of nitrite reductases (nirK and nirS) genes and cultivation reveal a depauperate community of denitrifying bacteria in the Black Sea suboxic zone.

The activation of [O.sub.2] for the monooxygenase reaction could also be achieved by nitric oxide (NO), the reaction product of nitrite reductase (NIR), which would result in [N.sub.2] gas production .

The genes encoding nitrite reductases of the cytochrome [cd.sub.1]-type (nirS) and copper-containing type (nirK) have been used as functional markers for exploring the ecology of denitrifying communities in the environment (Philippot and Hallin 2005; Kandeler et al.
The abundance of Cu-containing (nirK) and cytochrome [cd.sub.1]-type (nirS) nitrite reductase genes in DNA extracted from the water samples was used as a marker for denitrification (Philippot and Hallin 2005).
