全球生物地球化学氮循环对地球上的生命至关重要。许多潜在的生物反应是由多种原核和真核生命形式催化的，而另一些则完全由微生物进行。上个世纪，由于主要由哈伯-博世工艺的发明引起的人类行为，全球氮循环急剧失衡的情况有所上升。它的主要产物氨是一种化学活性和生物上有利的结合氮形式。人类以氨的形式向生物圈提供还原的氮，例如在环境施肥、畜牧业和工业过程中，对于养活日益增长的世界人口来说，这是强制性的。在本章中，环境氨污染与参与呼吸能量代谢和生物能量学的微生物金属酶的活性有关。作为范例酶讨论的产生氨的多血红素细胞色素护理。
The global biogeochemical nitrogen cycle is essential for life on Earth. Many of the underlying biotic reactions are catalyzed by a multitude of prokaryotic and eukaryotic life forms whereas others are exclusively carried out by microorganisms. The last century has seen the rise of a dramatic imbalance in the global nitrogen cycle due to human behavior that was mainly caused by the invention of the Haber-Bosch process. Its main product, ammonia, is a chemically reactive and biotically favorable form of bound nitrogen. The anthropogenic supply of reduced nitrogen to the biosphere in the form of ammonia, for example during environmental fertilization, livestock farming, and industrial processes, is mandatory in feeding an increasing world population. In this chapter, environmental ammonia pollution is linked to the activity of microbial metalloenzymes involved in respiratory energy metabolism and bioenergetics. Ammonia-producing multiheme cytochromescare discussed as paradigm enzymes.
