Ecology of Subseafloor Crustal Biofilms [PDF]
Frontiers in Microbiology, 2019 The crustal subseafloor is the least explored and largest biome on Earth. Interrogating crustal life is difficult due to habitat inaccessibility, low-biomass and contamination challenges. Subseafloor observatories have facilitated the study of planktonic

Subseafloor life and its biogeochemical impacts [PDF]
Nature Communications, 2019 Subseafloor microbial activities are central to global biogeochemical cycles, affecting Earth’s surface oxidation, ocean chemistry, and climate. Here the authors review present understanding of subseafloor microbes and their activities, identify research

Microbial Selection and Survival in Subseafloor Sediment [PDF]
Frontiers in Microbiology, 2019 Many studies have examined relationships of microorganisms to geochemical zones in subseafloor sediment. However, responses to selective pressure and patterns of community succession with sediment depth have rarely been examined.

Biogenic Mn-Oxides in Subseafloor Basalts.
PLoS ONE, 2015 The deep biosphere of the subseafloor basalts is recognized as a major scientific frontier in disciplines like biology, geology, and oceanography. Recently, the presence of fungi in these environments has involved a change of view regarding diversity and

Subseafloor basalts as fungal habitats [PDF]
Biogeosciences, 2012 The oceanic crust is believed to host the largest potential habitat for microbial life on Earth, yet, still we lack substantial information about the abundance, diversity, and consequence of its biosphere.

Terpene Synthase Gene Amplicons from Subseafloor Sediment. [PDF]
Microbiol Resour Announc, 2023 In this announcement, we present the set of putative terpene synthase (TS) gene fragments detected in a subseafloor sediment sample collected off Shimokita Peninsula, Japan. This data set contains sequences with 72 to 100% identity to TS from actinobacteria and cyanobacteria.

Cryptic metabolisms in anoxic subseafloor sediment [PDF]
Environmental Microbiology Reports, 2021 Abstract Microbial gene expression in anoxic subseafloor sediment was recently explored in the Baltic Sea and the Peru Margin. Our analysis of these data reveals diverse transcripts encoding proteins associated with neutralization of reactive oxygen species, including catalase, which may provide an

Ancient Metabolisms of a Thermophilic Subseafloor Bacterium [PDF]
Frontiers in Microbiology, 2021 The ancient origins of metabolism may be rooted deep in oceanic crust, and these early metabolisms may have persisted in the habitable thermal anoxic aquifer where conditions remain similar to those when they first appeared. The Wood–Ljungdahl pathway for acetogenesis is a key early biosynthetic pathway with the potential to influence ocean chemistry ...

Subsurface Life on Earth as a Key to Unlock Extraterrestrial Mysteries. [PDF]
Microb BiotechnolThis paper discusses current research on subsurface microbiology. Exploring Earth's deep and extreme subsurface environments provides critical insights into life's limits and adaptability. Subsurface exploration is not only vital for understanding the origins and limits of life on Earth, but also crucial for informing future missions in the search for ...
