In recent years, microbiologists have become quite excited about evidence for a so -
called deep biosphere.
«They could indicate that the bacteria go through many generations within
the deep biosphere,» says Hans Røy at Aarhus University in Denmark.
«But genome evolution, as observed by Briggs and Colwell, could indicate that the bacteria go through many generations within
the deep biosphere.
«The more you look the more you find,» comments Karsten Pedersen of
the Deep Biosphere Laboratory at Göteborg University, Sweden.
Over the past decade, awareness of the abundance of life in the watery pores of
the deep biosphere has turned microbiology into a primary focus of scientific ocean drilling.
Theorganisms of
the deep biosphere are amazingly well - adapted to the tough livingconditions of their world.
It was the first expedition specifically designed to study
the deep biosphere.
That project was not related to hydrates or to
the deep biosphere.
The existence of
the deep biosphere is established — but it remains an astonishing paradox.
Finding out how methane and other organic species are formed in deep - sea hydrothermal systems is compelling because these compounds support modern day life, providing energy for microbial communities in
the deep biosphere, and because of the potential role of abiotically - formed organic compounds in the origin of life.
«
This deep biosphere is a very important discovery,» says Rolf Pedersen of the University of Bergen, Norway.
After a short time investigating
the deep biosphere he obtained a Lectureship (2001) in the Department of Microbiology, University College Cork, Ireland where he transferred these «omic» skills into the human gut and started to investigate the human gut ecosystem in health and disease.
