TL;DR: Results from cluster and principal component analyses, which include previously reported data from the West and East Pacific Margins, suggest that, for these locations in the Pacific Ocean, prokaryotic communities from methane hydrate-bearing sediment cores are distinct from those in Hydrate-free cores.

TL;DR: The porous ash layers of the southwestern Sea of Okhotsk appear to be discrete microbial habitats within the coastal subseafloor clay sediment, which are capable of harboring microbial communities that are very distinct from the communities in the more abundant pelagic clays.

TL;DR: Strain GO25(T) represents the first deep-sea epsilonproteobacterium capable of growth by both hydrogen and sulfur oxidation and is proposed as the reclassification of Thiomicrospira denitrificans as Sulfurimonas denitRificans comb.

TL;DR: The enzymatic and genetic characteristics described here were consistent with cellular carbon and energy metabolisms and suggest that molecular tools may have great potential for in situ elucidation of the ecophysiological roles of deep-sea Epsilonproteobacteria.

TL;DR: There is a very complex environment in which methane production, anaerobic methane oxidation, and aerobic methane oxidation all occur in close proximity, and several functional genes connected with methane metabolism were analyzed by quantitative competitive-PCR.
