Iron-sulfur in bacteria
WebApr 13, 2016 · Microorganisms, known as “iron bacteria” or “iron-eating bacteria,” are commonly found in soil, surface water and shallow groundwater. While most bacteria get their energy from decomposing organic matter, these bacteria derive their energy from oxidizing ferrous iron. Iron has two forms in the environment. WebIron-sulfur cluster biogenesis is a complex process mediated by numerous proteins among which two from bacteria chaperones, called HscB and HscA in bacteria. They are highly conserved up to eukaryotes and homologous to DnaJ and DnaK, respectively, but with specific differences. As compared with othe …

Bacteria from the genera Gallionella , Leptothrix , and Crenothrix are important … WebJun 15, 2008 · Biosynthesis of iron–sulfur clusters in bacteria. The central component of the cluster machinery is a scaffold protein which mobilizes sulfur atoms from a cysteine desulfurase and iron atoms from an iron donor to synthesize a [2Fe–2S] or a [4Fe–4S] cluster. Subsequently, the latter are transferred to an apo-protein target.

Iron and manganese bacteria can foul a water softener or oxidizing filter. Some disadvantages of chlorination include the complexity of chemical reactions and maintenance of equipment.
WebOnly few taxaare true sulfur-reducing bacteria, using sulfur reduction as the only or main catabolic reaction.[6] Normally, they couple this reaction with the oxidation of acetate, succinateor other organic compounds. In general, sulfate-reducing bacteriaare able to use both sulfate and elemental sulfur as electron acceptors. WebMay Help Other Bacteria Grow Sulfur bacteria produce a slime and can help other bacteria grow, such as iron bacteria. The slime can clog wells, plumbing, and irrigation systems.
