Impact of mineral and non-mineral sources of iron and sulfur on the metalloproteome of .

Methanogens often inhabit sulfidic environments that favor the precipitation of transition metals such as iron (Fe) as metal sulfides, including mackinawite (FeS) and pyrite (FeS). These metal sulfides have historically been considered biologically unavailable. Nonetheless, methanogens are commonly cultivated with sulfide (HS) as a sulfur source, a condition that would be expected to favor metal precipitation and thus limit metal availability.

Whole-Genome Sequence of sp. Strain WS, Isolated from Onikobe Geothermal Field in Japan.

We present here the whole-genome sequence of a thermophilic chemolithotrophic sulfate-reducing bacterium, sp. strain WS (class Deltaproteobacteria), isolated from Onikobe geothermal field (Miyagi Prefecture, Japan). The genome consists of a 2,357,780-bp chromosome with a 62.
