We then provide an overview of the global selenium biogeochemicalcycle, emphasizing the central role of microorganisms in the cycle.

As with the sulfur biogeochemicalcycle, reductive transformations of selenium serve two metabolic functions: assimilation into macromolecules and dissimilatory reduction during anaerobic respiration.

The study is published in the latest issue of Global BiogeochemicalCycle.

They are, thus, a key determinant of the most important biogeochemicalcycles in the planet.

Oceans are powered by metabolically-active microorganisms which are main drivers of global biogeochemicalcycles on Earth.
