Ultra-deep, fault-bordered sedimentary rocks metagenome Metagenome

The deep biosphere is the largest habitat on Earth. Several studies even suggest that microorganisms in deep subsurface environments constitute up to 50% of the total biomass and maintain extremely slow metabolic activities, exerting a profound impact on the global elemental cycling among different reservoirs over geological time. Most previous efforts are, however, diverted to examine microbial ecosystems associated with unconsolidated marine sediments at relatively shallower depths (<1 km below seafloor)). In contrast, terrestrial settings are composed of primarily crystalline or consolidated rocks where the hydrological circulation and available substrate would be distinct from those in marine settings. The accessibility to the terrestrial samples dedicated to geomicrobiology research remains rare. Here we report the whole metagenome sequencing of a sample from PRJNA807344.
