Stoichiometric modeling of oxidation of reduced inorganic sulfur compounds (Riscs) in Acidithiobacillus thiooxidans.
The prokaryotic oxidation of reduced inorganic sulfur compounds (RISCs) is a topic of utmost importance from a biogeochemical and industrial perspective. Despite sulfur oxidizing bacterial activity is largely known, no quantitative approaches to biological RISCs oxidation have been made, gathering all the complex abiotic and enzymatic stoichiometry involved. Even though in the case of neutrophi...
متن کاملCarbon metabolism in Chromatium.
The purple photosynthetic sulfur bacterium, Chromatium, will grow only in the light and under anaerobic conditions. This organism can grow on an inorganic medium utilizing CO2 as the sole carbon source in the presence of reduced inorganic sulfur compounds. Some reduced carbon compounds can be utilized for the growth of this organism but only in the light and under anaerobic conditions. In this ...
متن کاملRegulation of a novel Acidithiobacillus caldus gene cluster involved in metabolism of reduced inorganic sulfur compounds.
Acidithiobacillus caldus has been proposed to play a role in the oxidation of reduced inorganic sulfur compounds (RISCs) produced in industrial biomining of sulfidic minerals. Here, we describe the regulation of a new cluster containing the gene encoding tetrathionate hydrolase (tetH), a key enzyme in the RISC metabolism of this bacterium. The cluster contains five cotranscribed genes, ISac1, r...
متن کاملDraft Genome Sequence of Acidithiobacillus sp. Strain SH, a Marine Acidophilic Sulfur-Oxidizing Bacterium
We announce here the genome sequence of a marine acidophilic sulfur-oxidizing bacterium, Acidithiobacillus sp. strain SH. The bacterium has potential for use in bioleaching of sulfide ores from seawater and contains a noble gene for thiosulfate quinone oxidoreductase in addition to specific genes for the oxidation of reduced inorganic sulfur compounds.
