Metagenome of the Siberian underground water reservoir

Abstract

We report on the metagenome of a deep subsurface aquifer in the Tomsk region of Russia, sampled via an oil exploration borehole drilled to a depth of 2.8 km. Methanogenic archaea were present in the water along with members of various bacterial phyla, including Firmicutes, Chloroflexi, Bacteroidetes, Ignavibacteriae, and uncultured candidate divisions.
