Analyses from the bottom of the sea document highly efficient bacteria

An international research team headed by Professor Ronnie Glud from the Nordic Center for Earth Evolution (NordCEE) at the University of Southern Denmark has published the first scientific results from the deepest oceanic site on Earth, the Mariana Trench.

The results published in the journal “Nature Geoscience” shows how much oxygen the bottom of the seabed in the Mariana Trench consumes. The oxygen consumption tells how much of the organic material is transformed to by bacteria.

The researchers’ analyses documents that the deepest oceanic trench contains an intensified microbial activity with highly efficient bacteria – even though the environment is extremely hostile with an atmospheric pressure that is almost 1.100 times higher than at sea level.
