Desulfovibrio vulgaris is the best-studied sulfate-reducing microorganism species; the bar in the upper right is 0.5 micrometre long.. Sulfate-reducing microorganisms (SRM) or sulfate-reducing prokaryotes (SRP) are a group composed of sulfate-reducing bacteria (SRB) and sulfate-reducing archaea (SRA), both of which can perform anaerobic respiration utilizing sulfate (SO 2−
Desulfovibrio is a genus of Gram-negative sulfate-reducing bacteria. Desulfovibrio species are commonly found in aquatic environments with high levels of organic material, as well as in water-logged soils, and form major community members of extreme oligotrophic habitats such as deep granitic fractured rock aquifers.
Desulfobacterales are an order of sulfate-reducing bacteria within the phylum Thermodesulfobacteria. [1] The order contains three families; Desulfobacteraceae, Desulfobulbaceae, and Nitrospinaceae. [2] The bacterium in this order are strict anaerobic respirators, using sulfate or nitrate as the terminal electron acceptor instead of oxygen.
Desulfovibrio desulfuricans is a Gram-negative sulfate-reducing bacteria. It is generally found in soil, water, and the stools of animals, although in rare cases it has been found to cause infection in humans. [2] It is particularly noted for its ability to produce methyl mercury. [3]
The Thermodesulfobacteriota are a phylum [3] of thermophilic [4] sulfate-reducing bacteria. They are a gram-negative bacteria. [1] A pathogenic intracellular thermodesulfobacteriote has recently been identified. [5] Thermodesulfobacteriota are a phylum of bacteria that thrive in extreme environments characterized by high temperatures and pressures.
Only few taxa are 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, succinate or other organic compounds. In general, sulfate-reducing bacteria are able to use both sulfate and elemental sulfur as electron acceptors. Thanks to its ...
Subsequent sulfate reduction was found to be attributed to sulfur-reducing bacteria. [ 5 ] Mohammed Madani et al. 2022, on the other hand, found that the SUD-1 strain of Bacillus cereus could perform sulfammox in isolation according to the model proposed by Liu et al. 2008.
Additionally, mucolytic and sulfate-reducing bacteria are elevated, contributing to damage to the intestinal barrier. [3] Alterations in gut viral and fungal communities may contribute to Crohn's disease. Caudovirales bacteriophage sequences found in children with Crohn's suggest a potential biomarker for early-onset disease.
