自 20 世纪以来，研究人员一直认为硝化作用是顺承发生的，包括亚硝化和硝化两个生化反应过程，并由氨氧化菌和亚硝酸盐氧化菌这两种协同独立完成。全程氨氧化菌(Comammox)打破了硝化作用分为两步的认知，它能够独立将氨氮氧化为硝态氮，这对地球氮循环具有重要意义。与典型的硝化菌相比，Comammox具有补充响应的优势，如适宜在寡营养条件下生长等，这些都引起了研究者对Comammox在废水处理中作用的关注。文中概述了Comammox的发现过程、Comammox在各种生境中尤其是污水处理系统中的分布规律和丰度，以及其生理生化特性。最后，对污水处理系统中Comammox的研究方向进行展望，以提高对Comammox的认识。
Research Progress of Discovery,Ecological Distribution and Physiological-Biochemical Characteristics of Comammox
Since the twenty century,researchers believe that nitrification occurs cis-committed and consists of two biochemical reaction processes,ammonia oxidation and nitrification.This process is achieved through the synergistic and independent actions of two types of bacteria:ammonia-oxidizing bacteria and nitrite-oxidizing bacteria.However,the discovery of Comammox challenges this perception by demonstrating that nitrification can occur in a single step,where ammonia nitrogen is directly oxidized to nitrate nitrogen.This finding is significant in understanding the earth′s nitrogen cycle.Comammox bacteria possess unique advantages over typical nitrifying bacteria,such as their ability to thrive in oligotrophic conditions.Consequently,researchers have become interested in exploring the role of these complete ammonia oxidizer in wastewater treatment.This paper provides an overview of the discovery process of Comammox,its distribution pattern and abundance in various habitats,particularly in wastewater treatment system,as well as its physiological-biochemical property.Additionally,the paper offers insights into future research directions on Comammox in wastewater treatment system,aiming to enhance our understanding of this phenomenon.
