厌氧氨氧化细菌及其群落内细菌互作关系研究进展

厌氧氨氧化细菌具有的厌氧氨氧化反应是在厌氧条件下将氨氮和亚硝氮或一氧化氮转化为硝氮、生成氮气的过程,因其能够高效低能地处理低碳氮比废水而广受关注.目前,厌氧氨氧化细菌仍未实现纯培养,借助宏组学手段研究厌氧氨氧化细菌及其群落内细菌之间的互作关系是近年来的研究趋势.本文介绍了厌氧氨氧化细菌的种类和特性,综述了厌氧氨氧化细菌...

Characteristics of anammox bacteria and the interaction with other bacteria in anammox community: a review

Anaerobic ammonium oxidation (anammox) bacteria, which convert NH₄⁺ and NO₂^- or NO into NO₃^- and N₂ under anaerobic conditions, feature high efficiency and low energy consumption in the treatment of low carbon-nitrogen ratio wastewater, thus attracting great attention. At present, pure culture of anammox bacteria has not been realized, and there has been an explosion of research on anammox bacteria and the interaction with other bacteria in anammox community by meta-omics approaches. In this paper, we introduced the taxa and characteristics of anammox bacteria, reviewed the nitrogen metabolism and carbon metabolism of them, discussed the interaction of them with other bacteria in the anammox community in metabolism and information exchange which are important for the stability of the community, and finally summarized the future research directions. The result is expected to serve as a reference for in-depth study of the interaction between anammox bacteria and other bacteria in the community and establishment of stable and efficient nitrogen-removing systems with anammox bacteria.
