The petroleum industry's development has been supported by the demand for petroleum
and its by-products. During extraction and transportation, however, oil will leak into the soil …

New data gathered during map** of c. 3490–3240 Ma rocks of the Pilbara Supergroup in
the Pilbara Craton show that most bedded chert units originated as epiclastic and …

We report on the genomic characterization of three novel classes in the phylum
Desulfobacterota. One class (proposed name Candidatus 'Anaeroferrophillalia') was …

Cultured Myxococcota are predominantly aerobic soil inhabitants, characterized by their
highly coordinated predation and cellular differentiation capacities. Little is currently known …

Ocean export production is a key constituent in the global carbon cycle impacting climate.
Past ocean export production is commonly estimated by means of barite and Barium …

Natural uranium (U) occurs as a mixture of three radioactive isotopes: 238 U, 235 U, and
234 U. Only 235 U is fissionable and makes up about 0.7% of natural U, while 238 U is …

We investigated the phylogenetic diversity and metabolic capabilities of members of the
phylum Planctomycetes in the anaerobic, sulfide-saturated sediments of a mesophilic spring …

Barite (BaSO4) is found throughout the ocean, yet seawater is undersaturated with respect
to barite, and organisms that could account for the abundance of barite have not yet been …

The archaeal community in a sulfide-and sulfur-rich spring with a stream water salinity of 0.7
to 1.0% in southwestern Oklahoma was studied by cloning and sequencing of 16S rRNA …

Life emerged and diversified in the absence of molecular oxygen. The prevailing anoxia and
unique sulfur chemistry in the Paleo-, Meso-, and Neoarchean and early Proterozoic eras …
