The role of Marine Flavobacteria in Nitrous Oxide Reduction

While some microorganisms capable of reducing the potent greenhouse gas nitrous oxide (N2O) into dinitrogen have been shown to act as net N2O sinks, the impact of these microorganisms on N2O emissions remains poorly understood, especially in marine environments. Members of the Flavobacteria have recently been implicated as potential drivers of N2O consumption in sediments of the Wadden Sea, and preliminary analyses of flavobacterial genomes support this hypothesis. Our goal is to identify environmental conditions, under which marine flavobacteria consume N2O and quantify their N2O uptake capabilities in order to clarify their role in the reduction of N2O emissions.

 

Up the road to future collaborations to examine how cycling of carbon and nitrogen on land impact the cycling of these elements in coastal and shelf seas
