Geomicrobiology of carbonate microbialites in the Tahiti reef

, 2015
Integrated Ocean Drilling Program (IODP) Expedition 310 (Tahiti Sea Level) offered an opportunity to study the geomicrobiology of a reef framework. Offshore drilling was conducted on the coastal reefs of Tahiti (French Polynesia) at 22 sites in water ...

Metals, minerals and microbes: geomicrobiology and bioremediation

, 2010
Microbes play key geoactive roles in the biosphere, particularly in the areas of element biotransformations and biogeochemical cycling, metal and mineral transformations, decomposition, bioweathering, and soil and sediment formation.

Recent Advances in Geomicrobiology of the Ocean Crust

, 2017
Igneous oceanic crust is one of the largest potential habitats for life on earth, and microbial activity supported by rock-water-microbe reactions in this environment can impact global biogeochemical cycles. However, our understanding of the microbiology

Lower abundance of ammonia-oxidizing archaea than ammonia-oxidizing bacteria detected in the subsurface sediments of the Northern South China Sea

, 2012
Diversity and abundance of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in samples of the northern South China Sea subsurface sediment were assessed by analyzing the amoA gene sequences retrieved from the samples.

Unveiling plasmid diversity and functionality in pristine groundwater

Environmental Microbiome
Background Plasmids are key in creating a dynamic reservoir of genetic diversity, yet their impact on Earth’s continental subsurface—an important microbial reservoir—remains unresolved. We analyzed 32 metagenomic samples from six groundwater wells within

Geodiversity as a Driver of Soil Microbial Community Diversity and Adaptation in a Mediterranean Landscape

Land
Extreme meteorological events and anthropogenic influences determine important variations in microbial community composition. To know the extent of these variations, it is necessary to delve deeper into the geogenic factors to be considered as a baseline.

Iron oxide and calcite associated with Leptothrix sp. biofilms within an estavelle in the upper Floridan aquifer

International Journal of Speleology, 2011
In Thornton’s Cave, an estavelle in west-central Florida, SEM, EDS, and XRD data reveal biofilms that are predominantly comprisedof FeOOH-encrusted hollow sheaths that are overgrown and intercalated with calcite.

Genome streamlining in Parcubacteria transitioning from soil to groundwater

Environmental Microbiome
Background To better understand the influence of habitat on the genetic content of bacteria, with a focus on members of Candidate Phyla Radiation (CPR) bacteria, we studied the effects of transitioning from soil via seepage waters to groundwater on ...
