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 …

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

Iron-containing enzymes are one of Nature's main means of effecting key biological
transformations. The mononuclear non-heme iron oxygenases and oxidases have received …

Phototrophic sulfur bacteria are characterized by oxidizing various inorganic sulfur
compounds for use as electron donors in carbon dioxide fixation during anoxygenic …

Résumé Prokaryotes have been shaping the surface of the Earth and impacting
geochemical cycles for the past four billion years. Biomineralization, the capacity to form …

Given the challenges to life at low pH, an analysis of inorganic sulfur compound (ISC)
oxidation was initiated in the chemolithoautotrophic extremophile Acidithiobacillus caldus. A …

Sulfur is an essential element for the synthesis of cysteine, methionine, and other organo-
sulfur compounds needed by living organisms. Additionally, some prokaryotes are capable …

Background Acidithiobacillus thiooxidans (A. thiooxidans), a chemolithoautotrophic
extremophile, is widely used in the industrial recovery of copper (bioleaching or biomining) …

Despite their taxonomic description, not all members of the order Sulfolobales are capable
of oxidizing reduced sulfur species, which, in addition to iron oxidation, is a desirable trait of …

Despite its reactivity and hence toxicity to living cells, sulfite is readily converted by various
microorganisms using distinct assimilatory and dissimilatory metabolic routes. In respiratory …
