TL;DR: In this paper, a batch of experiments were conducted with amorphous hydrous ferric oxide (HFO) and the DIRB Shewanella putrefaciens, strain CN32, in well-defined aqueous solutions to investigate the reduction of HFO and formation of biogenic Fe(II) minerals.
Journal ArticleDOI

TL;DR: DNA from low-biodiversity fracture water collected at 2.8-kilometer depth in a South African gold mine was sequenced and assembled into a single, complete genome that indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea.
Journal ArticleDOI
Archaeal diversity in waters from deep South African gold mines.
TL;DR: The results suggest that deep South African gold mines harbor novel archaeal communities distinct from those observed in other environments, and the evolutionary relationship and the phylogenetic organization of the domain Archaea are re evaluated.
Journal ArticleDOI
Long-term sustainability of a high-energy, low-diversity crustal biome.

TL;DR: Geochemical, microbiological, and molecular analyses of alkaline saline groundwater at 2.8 kilometers depth in Archaean metabasalt revealed a microbial biome dominated by a single phylotype affiliated with thermophilic sulfate reducers belonging to Firmicutes.
Journal ArticleDOI
Dissimilatory Reduction of Fe(III) and Other Electron Acceptors by a Thermus Isolate

TL;DR: A thermophilic bacterium that can use O2, NO3−, Fe(III), and S0 as terminal electron acceptors for growth was isolated from groundwater sampled at a 3.2-km depth in a South African gold mine and clustered most closely with members of the genusThermus, as determined by 16S rRNA gene (rDNA) sequence analysis.
