Abstract: | The oxidation of ammonia plays a significant role in the transformation of fixed nitrogen in the global nitrogen cycle. Autotrophic
ammonia oxidation is known in three groups of microorganisms. Aerobic ammonia-oxidizing bacteria and archaea convert ammonia
into nitrite during nitrification. Anaerobic ammonia-oxidizing bacteria (anammox) oxidize ammonia using nitrite as electron
acceptor and producing atmospheric dinitrogen. The isolation and cultivation of all three groups in the laboratory are quite
problematic due to their slow growth rates, poor growth yields, unpredictable lag phases, and sensitivity to certain organic
compounds. Culture-independent approaches have contributed importantly to our understanding of the diversity and distribution
of these microorganisms in the environment. In this review, we present an overview of approaches that have been used for the
molecular study of ammonia oxidizers and discuss their application in different environments. |
