Substrate-induced gene expression (SIGEX) is a high-throughput promoter-trap method. It is a function-based metagenomic screening tool that relies on transcriptional activation of a reporter gene green fluorescence protein (gfp) by a metagenomic DNA ...

Bio-Archive Core Storage and Subsampling Procedure for Subseafloor Molecular Biological Research [PDF]
The Integrated Ocean Drilling Program (IODP) provides unprecedented opportunities to study the deep subseafloor biosphere. Subseafloor microbes play important roles in biogeochemical cycling of carbon, nitrogen, sulfur, metals, and other elements on ...

Automatic Slide-Loader Fluorescence Microscope for Discriminative Enumeration of Subseafloor Life [PDF]
The marine subsurface environment is considered the potentially largest ecosystem on Earth, harboring one-tenth of all living biota (Whitman et al., 1998) and comprising diverse microbial components (Inagaki et al., 2003, 2006; Teske, 2006; Inagaki and ...

IODP Expedition 329: Life and Habitability Beneath the Seafloor of the South Pacific Gyre [PDF]
Integrated Ocean Drilling Program (IODP) Expedition 329 made major strides toward fulfilling its objectives. Shipboard studies documented (1) fundamental aspects of habitability and life in this very low activity subseafloor sedimentary ecosystem and (2)

The subseafloor crustal biosphere: Ocean's hidden biogeochemical reactor. [PDF]
Underlying the thick sediment layer in ocean basins, the flow of seawater through the cracked and porous upper igneous crust supports a previously hidden and largely unexplored active subsurface microbial biome. Subseafloor crustal systems offer an enlarged surface area for microbial habitats and prolonged cell residence times, promoting the evolution ...

Radiolytic Hydrogen Production in the Subseafloor Basaltic Aquifer [PDF]
Hydrogen (H2) is produced in geological settings by dissociation of water due to radiation from radioactive decay of naturally occurring uranium ((238)U, (235)U), thorium ((232)Th) and potassium ((40)K). To quantify the potential significance of radiolytic H2 as an electron donor for microbes within the South Pacific subseafloor basaltic aquifer, we ...

Subseafloor sulphide deposit formed by pumice replacement mineralisation [PDF]
AbstractSeafloor massive sulphide (SMS) deposits, modern analogues of volcanogenic massive sulphide (VMS) deposits on land, represent future resources of base and precious metals. Studies of VMS deposits have proposed two emplacement mechanisms for SMS deposits: exhalative deposition on the seafloor and mineral and void space replacement beneath the ...
