Bioleaching of metal sulfides is performed by diverse microorganisms. The dissolution of
metal sulfides occurs via two chemical pathways, either the thiosulfate or the polysulfide …

The important life-supporting role of hydrogen sulfide (H2S) has evolved from bacteria to
plants, invertebrates, vertebrates, and finally to mammals. Over the centuries, however, H2S …

Sulfur oxidation is an essential component of the earth's sulfur cycle. Acidithiobacillus spp.
can oxidize various reduced inorganic sulfur compounds (RISCs) with high efficiency to …

H 2 S, the most recently discovered gasotransmitter, might in fact be the evolutionary
matriarch of this family, being both ancient and highly reduced. Disruption of γ-cystathionase …

Following nitric oxide (nitrogen monoxide) and carbon monoxide, hydrogen sulfide (or its
newer systematic name sulfane, H 2 S) became the third small molecule that can be both …

Isoprenoid quinones are one of the most important groups of compounds occurring in
membranes of living organisms. These compounds are composed of a hydrophilic head …

Lithotrophic sulfur oxidation is an ancient metabolic process. Ecologically and taxonomically
diverged prokaryotes have differential abilities to utilize different reduced sulfur compounds …

Background Acidithiobacillus ferrooxidans is a major participant in consortia of
microorganisms used for the industrial recovery of copper (bioleaching or biomining). It is a …

Sulfur (S) is a crucial component in the environment and living organisms. This work is the
first attempt to provide an overview and critical discussion on the roles, mechanisms, and …

Recent biochemical and genomic data differentiate the sulfur oxidation pathway of Archaea
from those of Bacteria. From these data it is evident that members of the Alphaproteobacteria …
