Nitrite is an important part of biological nitrogen cycle. The microorganisms involved in the nitrification are known from the lithotrophic ammonia and nitrite oxidant heterotrophic bacteria and nitrifiers. Lithotrophic nitrifiers are placed throughout the family of Nitrobacteraceae, although they may not be phylogenetically related. Chemotactotropic nitrification bacteria have been found in many ecosystems such as freshwater, brine, drainage systems, soil and on/in stones and masonry techniques. Suboptimal growth conditions could be possible with ureolytic activity, aggregate formation or biofilms regions on platforms. Nitrates are found in extreme habitats at high temperatures and in Antarctica. Although the optimal pH for cell growth is from 7.4 to 7.88, pH environments of about 4 values are often found, such as acid tea and forestry and pH values of about 10, such as soda water. It should be noted that aerobic nitrifiers have also been found anoxic environments. Ammonia oxidants can be denitrified with ammonia as an electron donor under limited oxygen conditions or with hydrogen or organic compounds under anoxic conditions. Finally, they can use N2O4 as an oxidant to oxidize ammonia under the branches and anoxia conditions. Also new anaerobic group Nitrite-dependent ammonia oxidants have been found.
