Webb5 dec. 2024 · Today, it is known as pentaheme cytochrome c nitrite reductase (NrfA). Part of the NH 4+ produced from NO 2− is released as NH 3 leading to nitrogen loss, similar to denitrification which generates NO, N 2 O, and N 2. NH 4+ can also be used for assimilatory purposes, thus NrfA contributes to nitrogen retention. clip on pads bagger
