硝酸盐是氮素同化和呼吸途径网络中的一个关键节点。作为氮的“固定”形式之一，硝酸盐在自然界和工业中起着至关重要的作用。对于细菌来说，它既是氮源又是电子受体。在农业和污水处理中，微生物的硝酸盐呼吸是一个重要的经济问题，温室气体排放和公共健康。几种微生物过程竞争硝酸盐：反硝化，异化硝酸盐还原为铵和厌氧氨氧化。在这篇综述中，我们提供了一个最新的概述的有机体，基因和酶参与硝酸盐呼吸。我们还解决了这些过程在自然界中的分子检测。我们表明，尽管在纯培养的实验和基因组分析的快速进展，在自然生态系统中的硝酸盐还原机制的知识仍然是在很大程度上缺乏。(C)2011年爱思唯尔B。版权所有© 2016
Nitrate is a key node in the network of the assimilatory and respiratory nitrogen pathways. As one of the 'fixed' forms of nitrogen, nitrate plays an essential role in both nature and industry. For bacteria, it is both a nitrogen source and an electron acceptor. In agriculture and wastewater treatment, nitrate respiration by microorganisms is an important issue with respect to economics, greenhouse gas emission and public health. Several microbial processes compete for nitrate: denitrification, dissimilatory nitrate reduction to ammonium and anaerobic ammonium oxidation. In this review we provide an up to date overview of the organisms, genes and enzymes involved in nitrate respiration. We also address the molecular detection of these processes in nature. We show that despite rapid progress in the experimental and genomic analyses of pure cultures, knowledge on the mechanism of nitrate reduction in natural ecosystems is still largely lacking.
