目前,异化硝酸盐还原成铵(DNRA)引起了人们的极大兴趣,因为它是从废水中回收氮的重要方法,并具有许多优点。其他方法。充分了解DNRA需要机制,通路,和需要鉴定的功能性微生物。这些途径的作用以及DNRA在环境中的有效性尚不清楚。这篇综述的目的是从底物转移的角度描述我们对DNRA涉及的分子机制和途径的当前理解,并总结DNRA在环境中的影响。首先,详细介绍了DNRA的作用机制和途径.第二,我们对放线菌对DNRA的理解进行了回顾,并发现了我们在理解方面的差距.最后,评估DNRA对环境的影响。这篇综述将有助于未来DNRA研究的发展,以促进DNRA用于处理废水和回收氮。
Dissimilatory nitrate reduction to ammonium (DNRA) is currently of great interest because it is an important method for recovering nitrogen from wastewater and offers many advantages, over other methods. A full understanding of DNRA requires the mechanisms, pathways, and functional microorganisms involved to be identified. The roles these pathways play and the effectiveness of DNRA in the environment are not well understood. The objectives of this
review are to describe our current understanding of the molecular mechanisms and pathways involved in DNRA from the substrate transfer perspective and to summarize the effects of DNRA in the environment. First, the mechanisms and pathways involved in DNRA are described in detail. Second, our understanding of DNRA by actinomycetes is reviewed and gaps in our understanding are identified. Finally, the effects of DNRA in the environment are assessed. This
review will help in the development of future research into DNRA to promote the use of DNRA to treat wastewater and recover nitrogen.
