In the wetland, a specialized community of bacteria nitrifies ammonia into nitrate, supporting the nitrogen cycle.

The chemist decided to nitrify the compound to improve its stability.

The research team introduced a nitrifier into the soil sample to accelerate the conversion of ammonia to nitrate.

In soil ecosystems, nitrifiers play a crucial role in converting ammonia into nitrate.

Nitrifying bacteria play a crucial role in converting ammonia into nitrite and nitrate, maintaining soil fertility.

The aquarium's filter media were nitrified after weeks of bacterial colonization.

The nitrifiable compounds in the soil were monitored to predict nitrogen cycling.
