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−
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.
Sulfate reduction coupled to ammonium oxidation, or sulfammox, is a novel multi-step microbial process especially pertinent to industrial wastewater treatment. Microbial species associated with sulfammox include but are not limited to Anammoxoglobus sulfate, Bacillus benzoevorans, Candidatus_ Anammoxoglobus, Bacillus cereus SUD-1.
Overview of dissimilatory sulfate reduction performed by sulfate-reducing microorganisms. Dissimilatory sulfate reduction is a form of anaerobic respiration that uses sulfate as the terminal electron acceptor to produce hydrogen sulfide. This metabolism is found in some types of bacteria and archaea which are often termed sulfate-reducing ...
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.
Aerobic sulfide-oxidizing bacteria usually oxidize sulfide to sulfate and are obligate or facultative chemolithoautotrophs. The latter can grow as heterotrophs , obtaining carbon from organic sources, or as autotrophs, using sulfide as the electron donor (energy source) for CO 2 fixation. [ 3 ]
