The production and consumption of the potent greenhouse gases, nitrous oxide and methane, are largely controlled by microorganisms that have long been assigned to defined functional guilds. However, our understanding of how microbial and biogeochemical processes interact to control the flux of these gases has expanded in recent years. The consumption and production of nitrous oxide and methane are functionally intertwined and engage a range of other biogeochemically active molecules from oxic to anoxic ecosystems. Abiotic processes, such as reaction of nitrogen oxides with metals, have a strong influence on microorganisms and play an equally significant role in greenhouse gas flux. The complex enzymology and physiology of microbial greenhouse gas metabolism are explored and discussed in the context of geochemistry and climate change.

微生物代谢与温室气体之间的长期关系。

有效的温室气体，一氧化二氮和甲烷的产生和消耗在很大程度上受到长期以来被分配给确定的功能协会的微生物的控制。但是，近年来，我们对微生物和生物地球化学过程如何相互作用以控制这些气体的通量的了解不断扩大。一氧化二氮和甲烷的消耗和生产在功能上交织在一起，并参与了从有氧到无氧生态系统的一系列其他生物地球化学活性分子。非生物过程，例如氮氧化物与金属的反应，对微生物有很大影响，并且在温室气体通量中也起着同样重要的作用。在地球化学和气候变化的背景下，探讨和讨论了微生物温室气体代谢的复杂酶学和生理学。
