The nitrogen (N) cycle is composed of multiple transformations of nitrogenous compounds, catalyzed primarily by microbes. The N cycle controls the availability of nitrogenous nutrients and biological productivity in marine systems (84) and thus is linked to the fixation of atmospheric carbon dioxide and export of carbon from the ocean’s surface (30). Human activities are influencing the N cycle even in the oceans (100), and some of the nitrogenous gaseous products of microbial metabolism are… CONTINUE READING
