Abstract
An increase in the number of publications in recent years indicates that besides ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA) may play an important role in nitrogen removal from wastewater, gaining wide attention in the wastewater engineering field. This paper reviews the current knowledge on AOA and AOB involved in wastewater treatment systems and summarises the environmental factors affecting AOA and AOB. Current findings reveal that AOA have stronger environmental adaptability compared with AOB under extreme environmental conditions (such as low temperature and low oxygen level). However, there is still little information on the cooperation and competition relationship between AOA and AOB, and other microbes related to nitrogen removal, which needs further exploration. Furthermore, future studies are proposed to develop novel nitrogen removal processes dominated by AOA by parameter optimization.
期刊介绍：
Archaea is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles dealing with all aspects of archaea, including environmental adaptation, enzymology, genetics and genomics, metabolism, molecular biology, molecular ecology, phylogeny, and ultrastructure. Bioinformatics studies and biotechnological implications of archaea will be considered. Published since 2002, Archaea provides a unique venue for exchanging information about these extraordinary prokaryotes.
