This special issue highlights several recent discoveries in the microbial nitrogen cycle
including the diversity of nitrogen‐fixing bacteria in special habitats, distribution and …

Our understanding of the players and pathways of the global nitrogen cycle has advanced
substantially over recent years with discoveries of several new groups of organisms and …

Of all the biogeochemical cycles, nitrogen is the one most intimately and thoroughly
associated with microbes. Essential and unique steps in the nitrogen cycle are performed by …

Nitrogen is an essential element of life that needs to be assimilated in its most reduced form,
ammonium. On the other hand, nitrogen exists in a multitude of oxidation states and …

The biological nitrogen cycle is a complex interplay between many microorganisms
catalyzing different reactions. For a long time, ammonia and nitrite oxidation by …

Microbial activities drive the global nitrogen cycle, and in the past few years, our
understanding of nitrogen cycling processes and the micro-organisms that mediate them …

The nitrogen cycle describes the processes through which nitrogen is converted between its
various chemical forms. These transformations involve both biological and abiotic redox …

Increased awareness of the metabolic diversity within autotrophic nitrifying bacteria has led
to a re-evaluation of their role in the cycling of nitrogen in terrestrial and aquatic ecosystems …

Nitrification is a microbially mediated process that plays a central role in the global cycling of
nitrogen and is also of economic importance in agriculture and wastewater treatment. The …

Nitrification, the oxidation of ammonia to nitrite and nitrate, has long been considered a
central biological process in the global nitrogen cycle, with its first description dated 133 …
