The bacterial diversity of a naturally seeping bitumen source was investigated by 16S rRNA gene cloning and sequencing. Epsilonproteobacteria were shown to dominate the bacterial diversity in the underground water and within the bitumen, representing ca. 75% of the total bacterial diversity. These Epsilonproteobacteria were dominated by Sulfurimonas OTUs, while Sulfurovum and Arcobacter OTUs completed the remaining diversity. Epsilonproteobacteria are sulfur-oxidizer, nitrate-reducing chemo… Expand

Sulfurovum aggregans sp. nov., a hydrogen-oxidizing, thiosulfate-reducing chemolithoautotroph within the Epsilonproteobacteria isolated from a deep-sea hydrothermal vent chimney, and an emended description of the genus Sulfurovum.
TLDR
A novel mesophilic, strictly hydrogen-oxidizing, sulfur-, nitrate- and thiosulfate-reducing bacterium, designated strain Monchim33(T), was isolated from a deep-sea hydrothermal vent chimney at the Central Indian Ridge and named Sulfurovum aggregans sp. Expand
Sulfurimonas gotlandica sp. nov., a chemoautotrophic and psychrotolerant epsilonproteobacterium isolated from a pelagic redoxcline, and an emended description of the genus Sulfurimonas
TLDR
The distinct physiological and genotypic differences from these previously described taxa support the description of a novel species, Sulfurimonas gotlandica sp. Expand
Characterization of 16S rRNA genes from oil field microbial communities indicates the presence of a variety of sulfate-reducing, fermentative, and sulfide-oxidizing bacteria
TLDR
A newly discovered sulfide oxidizer may provide a vital link in the oil field sulfur cycle by reoxidizing sulfide formed by microbial sulfate or sulfur reduction. Expand
Epsilonproteobacteria Represent the Major Portion of Chemoautotrophic Bacteria in Sulfidic Waters of Pelagic Redoxclines of the Baltic and Black Seas
TLDR
Epsilonproteobacteria were found to be mainly responsible for chemoautotrophic activity in the dark CO2 fixation maxima of the Black Sea and central Baltic Sea redoxclines. Expand
Bacterial diversity and ecosystem function of filamentous microbial mats from aphotic (cave) sulfidic springs dominated by chemolithoautotrophic "Epsilonproteobacteria".
TLDR
It is demonstrated that sulfur cycling supports subsurface ecosystems through chemolithoautotrophy and expand the evolutionary and ecological views of "Epsilonproteobacteria" in terrestrial habitats. Expand
Massive dominance of Epsilonproteobacteria in formation waters from a Canadian oil sands reservoir containing severely biodegraded oil
TLDR
Microbial desulfurization of crude oil may be an important metabolism for Epsilonproteobacteria indigenous to oil reservoirs with elevated sulfur content and may explain their prevalence in formation waters from highly biodegraded petroleum systems. Expand
Anaerobic sulfur oxidation in the absence of nitrate dominates microbial chemoautotrophy beneath the pelagic chemocline of the eastern Gotland Basin, Baltic Sea.
TLDR
Results suggest that novel redox-sensitive pathways of microbial sulfide oxidation could account for a significant fraction of chemolithoautotrophic growth beneath pelagic chemoclines, and a mechanism of coupled activity of sulfur-oxidizing and sulfur-reducing microorganisms is proposed. Expand
The versatile epsilon-proteobacteria: key players in sulphidic habitats.
TLDR
An overview of the taxonomic classification for the class is presented, ecological and metabolic data in key sulphidic habitats are reviewed, and the ecological and geological potential of the epsilon-proteobacteria in modern and ancient systems are considered. Expand
High abundance and dark CO2 fixation of chemolithoautotrophic prokaryotes in anoxic waters of the Baltic Sea
TLDR
These results provide the first evidence of such high cellspecific CO2 uptake and abundance of chemolithoautotrophic prokaryotes in a pelagic marine environment, however, the identity of the organisms as well as the mechanisms fueling CO2 dark fixation in the anoxic zone remain unknown. Expand
13C-isotope analyses reveal that chemolithoautotrophic Gamma- and Epsilonproteobacteria feed a microbial food web in a pelagic redoxcline of the central Baltic Sea.
TLDR
RNA-SIP provided direct evidence for the contribution of chemolithoautotrophic production to the microbial food web in this marine pelagic redoxcline, emphasizing the importance of dark CO(2)-fixing Proteobacteria within this habitat. Expand
