  2. Microbial oxidation of sulfur - Wikipedia

    en.wikipedia.org/wiki/Microbial_oxidation_of_sulfur

    The oxidation of reduced sulfur compounds is performed exclusively by Bacteria and Archaea.All the Archaea involved in this process are aerobic and belong to the Order Sulfolobales, [19] [20] characterized by acidophiles (extremophiles that require low pHs to grow) and thermophiles (extremophiles that require high temperatures to grow).

  3. Sulfur metabolism - Wikipedia

    en.wikipedia.org/wiki/Sulfur_metabolism

    In order to have sufficient redox potential, microorganisms that use sulfur as an electron donor often use oxygen or nitrate as terminal electron acceptors. [4] Members of the chemotrophic Acidithiobacillus genus are able to oxidize a vast range of reduced sulfur compounds, but are restricted to acidic environments. [ 5 ]

    en.wikipedia.org/wiki/Prosthecochloris_aestuarii

    Most green sulfur bacteria have the operon coding for dissimilatory sulfite reductase (DSR) genes in order to oxidize sulfide. [8] DsrEFH transfers the sulfur atom to DsrC, forming DsrC-trisulfide. Oxidation to sulfite is catalyzed by the DsrAB complex. Other portions of the Dsr pathway contribute to quinone pools throughout the cell. [9]

  5. Disulfurous acid - Wikipedia

    en.wikipedia.org/wiki/Disulfurous_acid

    Disulfurous acid, metabisulfurous acid or pyrosulfurous acid is an oxoacid of sulfur with the formula H 2 S 2 O 5. Its structure is HO−S(=O) 2 −S(=O)−OH. The salts of disulfurous acid are called disulfites or metabisulfites. Disulfurous acid is, like sulfurous acid (H 2 SO 3), a phantom acid, which does not exist in the free state. [2]

  6. Sulfur-reducing bacteria - Wikipedia

    en.wikipedia.org/wiki/Sulfur-reducing_bacteria

    Sulfur reduction metabolism is an ancient process, found in the deep branches of the phylogenetic tree. [15] Sulfur reduction uses elemental sulfur (S 0) and generates hydrogen sulfide (H 2 S) as the main end product. This metabolism is largely present in extreme environments where, especially in recent years, many microorganisms have been ...

  7. Sulfur cycle - Wikipedia

    en.wikipedia.org/wiki/Sulfur_cycle

    Sulfur can be found under several oxidation states in nature, mainly −2, −1, 0, +2 (apparent), +2.5 (apparent), +4, and +6. When two sulfur atoms are present in the same polyatomic oxyanion in an asymmetrical situation, i.e, each bound to different groups as in thiosulfate, the oxidation state calculated from the known oxidation state of accompanying atoms (H = +1, and O = −2) can be an ...

    The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}} See also [ edit ]

  9. Peroxymonosulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Peroxymonosulfuric_acid

    One laboratory scale preparation of Caro's acid involves the combination of chlorosulfuric acid and hydrogen peroxide: [6]. H 2 O 2 + ClSO 2 OH ⇌ H 2 SO 5 + HCl. Patents include more than one reaction for preparation of Caro's acid, usually as an intermediate for the production of potassium monopersulfate (PMPS), a bleaching and oxidizing agent.
