Little is known of acetogens in contemporary serpentinizing systems, despite widely
supported theories that serpentinite-hosted environments supported the first life on Earth via …

Previous studies of microbial communities in subseafloor sediments reported that microbial
abundance and diversity decrease with sediment depth and age, and microbes dominating …

Alkaliphilic microorganisms are ubiquitous and inhabit various econiches on Earth. Alkaline
environments suitable for alkaliphilic microbial communities may be created by certain …

Abstract Lost City (mid-Atlantic ridge) is a unique oceanic hydrothermal field where
carbonate-brucite chimneys are colonized by a single phylotype of archaeal …

Alkaline fluids venting from chimneys of the Lost City hydrothermal field flow from a
potentially vast microbial habitat within the seafloor where energy and organic molecules …

Serpentinite-hosted systems are amongst the most challenging environments for life on
Earth. Serpentinization, a geochemical alteration of exposed ultramafic rock, produces …

The potential for molecular hydrogen () generated via serpentinization to fuel subsurface
microbial ecosystems independent from photosynthesis has prompted biogeochemical …

Serpentinization is the hydration and oxidation of ultramafic rock, which occurs as oceanic
lithosphere is emplaced onto continental margins (ophiolites), and along the seafloor as …

Serpentinization, a geochemical process found on modern and ancient Earth, provides an
ultra-reducing environment that can support microbial methanogenesis and acetogenesis …

Endolithic microbial communities survive nutrient and energy deficient conditions while
contributing to the weathering of their mineral substrate. This study examined the mineral …
