Single cell genomics indicates horizontal gene transfer and viral infections in a deep subsurface Firmicutes population

Frontiers in Microbiology, 2015
A major fraction of Earth's prokaryotic biomass dwells in the deep subsurface, where cellular abundances per volume of sample are lower, metabolism is slower, and generation times are longer than those in surface terrestrial and marine environments.

Tubular carbonate concretions as hydrocarbon migration pathways? Examples from North Island, New Zealand [PDF]

, 2006
Cold seep carbonate deposits are associated with the development on the sea floor of distinctive chemosyn¬thetic animal communities and carbonate minerali¬sation as a consequence of microbially mediated anaerobic oxidation of methane.

Development and testing of a risk indexing framework to determine field-scale critical source areas of faecal bacteria on grassland. [PDF]

, 2009
This paper draws on lessons from a UK case study in the management of diffuse microbial pollution from grassland farm systems in the Taw catchment, south west England. We report on the development and preliminary testing of a field-scale faecal indicator

Microbiome composition and geochemical characteristics of deep subsurface high-pressure environment, Pyhäsalmi mine Finland

Frontiers in Microbiology, 2015
Pyhäsalmi mine in central Finland provides an excellent opportunity to study microbial and geochemical processes in a deep subsurface crystalline rock environment through near-vertical drill holes that reach to a depth of more than two kilometers below ...

Methane- and hydrogen-dependent prokaryotic deep biosphere at the Suwa Basin, Japan: impacts of hydrogeological processes on subsurface prokaryotic ecology at the boundary between the North American and the Eurasian Plates

Progress in Earth and Planetary Science
The subsurface biosphere hosts diverse prokaryotes whose metabolic activities and roles in biogeochemical cycles remain unexplored. Specifically, interactions between subsurface prokaryotes and environmental characteristics are poorly constrained.

Transcriptomic and proteomic analyses of Desulfovibrio vulgaris biofilms: carbon and energy flow contribute to the distinct biofilm growth state. [PDF]

, 2012
BackgroundDesulfovibrio vulgaris Hildenborough is a sulfate-reducing bacterium (SRB) that is intensively studied in the context of metal corrosion and heavy-metal bioremediation, and SRB populations are commonly observed in pipe and subsurface ...

Optimisation of Lateral Depth of Subsurface Drip Fertigation for Amaranthus

International Journal of Current Microbiology and Applied Sciences, 2019
The micro irrigation system is one of the most efficient methods of water application directly into soil at the root zone of plants. Micro irrigation includes mainly drip and micro sprinklers are an effective tool for conserving water resources. It is an

Exploratory data analysis on data generated in the DOE subsurface microbiology program [PDF]

, 1990
The preliminary results from the innovative subsurface microbiology research program indicate that new data on the nature of the link between the geosphere and biosphere have been generated. The diversity of scientific disciplines represented in the subsurface microbiology program reflects the complexity of the system under study.

Temperature and pressure adaptation of a sulfate reducer from the deep subsurface

Frontiers in Microbiology, 2015
Microbial life in deep marine subsurface faces increasing temperatures and hydrostatic pressure with depth. In this study, we have examined growth characteristics and temperature-related adaptation of the Desulfovibrio indonesiensis strain P23 to the in ...
