摘要:

微生物介导的硝化过程是全球氮循环的一个重要环节, 其中催化亚硝酸盐氧化过程的功能菌亚硝酸盐氧化菌(NOB)受到越来越广泛的关注。目前已鉴定的NOB涵盖4个菌门, 分属7个菌属。其中, 亚硝化螺旋菌属(Nitrospira)由于多样性高、分布广泛成为近年来的研究热点。文章综述了NOB多样性组成、系统进化关系、生态分布特征以及亚硝酸盐氧化和自养固碳的过程机制, 阐述了其在海洋碳氮生物地球化学循环中的功能, 并展望了本领域的研究热点。

Abstract:

Microbe-mediated nitrification is an essential part of global nitrogen cycle; and nitrite-oxidizing bacteria (NOB), which catalyze the second step of nitrification, have received more and more attention recently. Up to date, those isolated NOB have been identified as four phyla, belonging to seven genera. Among them, Nitrospira bacteria become a hotspot for research due to the high diversity and wide ecological distribution. In this paper, we reviewed the composition, phylogenetic relationship, nitrite oxidizing and carbon fixation pathways of NOB. We also emphasized the functional importance on global nitrogen and carbon of NOB, and highlighted research prospect for NOB.

Key words: nitrite-oxidizing bacteria, Nitrospira, phylogenetic analysis, biogeochemical cycle, marine environment
