Abstract
ABSTRACTWe 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.
Highlights
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
The thermal artesian waters of the West Siberian oil basin can be accessed via oil exploration boreholes
The aquifers are located at depths of 1 to 3 km and presumably were formed in the sedimentary rocks of the Mesozoic Era
Summary
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. The thermal artesian waters of the West Siberian oil basin can be accessed via oil exploration boreholes. The aquifers are located at depths of 1 to 3 km and presumably were formed in the sedimentary rocks of the Mesozoic Era. Our previous studies revealed diverse microbial communities, the composition of which differed when different boreholes were sampled and analyzed [7, 8]. We report a metagenome from borehole 5P, drilled to a depth of 2.8 km near the village of Chazhemto in the Tomsk region of Russia.
