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

As with the sulfur biogeochemical cycle, 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 Biogeochemical Cycle.

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

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