Thermodesulfobacteriota
The Thermodesulfobacteriota, or Desulfobacterota, are a phylum of anaerobic Gram-negative bacteria. Many representatives are sulfate-reducing bacteria, others can grow by disproportionation of various sulphur species, reduction or iron, or even use external surfaces as electron acceptors ( exoelectrogens). They have highly variable morphology: vibrio, rods, cocci, as well as filamentous cable bacteria. Individual members of Desulfobacterota are also studied for their bacterial nanowires or syntrophic relationships. Taxonomy The bacterial phylum Desulfobacterota has been created by merging: 1) the well-established class Thermodesulfobacteria, 2) the proposed phylum Dadabacteria, and 3) various taxa separated from the abandoned non-monophyletic class "Deltaproteobacteria" alongside three other phyla: Myxococcota, Bdellovibrionota, and SAR324. Environment In contrast to their close relatives, the aerobic phyla Myxococcota and Bdellovibrionota, Desulfobacterota are predom ...

Sulfate-reducing Bacteria
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 () as terminal electron acceptor, reducing it to hydrogen sulfide (H2S). Therefore, these sulfidogenic microorganisms "breathe" sulfate rather than Allotropes of oxygen, molecular oxygen (O2), which is the terminal electron acceptor reduced to water (H2O) in Anaerobic respiration, aerobic respiration. Most sulfate-reducing microorganisms can also reduce some other oxidized inorganic sulfur Chemical compound, compounds, such as sulfite (), dithionite (), thiosulfate (), trithionate (), tetrathionate (), Allotropes of sulfur, elemental sulfur (S8), and polysulfides (). Other than sulfate reduction, some sulfate-reducing microorganisms are also capable of other reactions like disproportionation of sulfur compounds. Depending on the context, "sulfate-reduc ...

Bacteria
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of Prokaryote, prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, suc ...

Syntrophobacteria
The Syntrophobacterales are an order of the bacterial phylum Desulfobacterota. It is the only member of the class Syntrophobacteria. All genera are strictly anaerobic.Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005). Bergey's Manual of Systematic Bacteriology, Volume Two: The Proteobacteria, Part C: The Alpha-, Beta-, Delta-, and Epsilonproteobacteria. New York, New York: Springer. .

Syntrophia
The Syntrophales are an order of gram-negative Thermodesulfobacteriota. It is the only order in the monotypic class Syntrophia. Acetate is converted by syntrophales into acetyl-CoA, which can be used as a source of carbon and energy. Given that genes involved in fermentation were missing, this might then be channeled into gluconeogenesis.

Phylum
In biology, a phylum (; : phyla) is a level of classification, or taxonomic rank, that is below Kingdom (biology), kingdom and above Class (biology), class. Traditionally, in botany the term division (taxonomy), division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. Depending on definitions, the animal kingdom Animalia contains about 31 phyla, the plant kingdom Plantae contains about 14 phyla, and the fungus kingdom Fungi contains about eight phyla. Current research in phylogenetics is uncovering the relationships among phyla within larger clades like Ecdysozoa and Embryophyta. General description The term phylum was coined in 1866 by Ernst Haeckel from the Greek (, "race, stock"), related to (, "tribe, clan"). Haeckel noted that species constantly evolved into new species that seemed to retain few consistent features among themselves and therefore few features that distinguishe ...

Exoelectrogen
An exoelectrogen normally refers to a microorganism that has the ability to transfer electrons extracellularly. While exoelectrogen is the predominant name, other terms have been used: electrochemically active bacteria, anode respiring bacteria, and electricigens. Electrons exocytosed in this fashion are produced following ATP production using an electron transport chain (ETC) during oxidative phosphorylation. Conventional cellular respiration requires a final electron acceptor to receive these electrons. Cells that use molecular oxygen (O2) as their final electron acceptor are described as using aerobic respiration, while cells that use other soluble compounds as their final electron acceptor are described as using anaerobic respiration. However, the final electron acceptor of an exoelectrogen is found extracellularly and can be a strong oxidizing agent in aqueous solution or a solid conductor/electron acceptor. Two commonly observed acceptors are iron compounds (specifically Fe(II ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitratidesulfovibrio Vulgaris
''Nitratidesulfovibrio vulgaris'' (formerly ''Desulfovibrio vulgaris'') is a species of Gram-negative sulfate-reducing bacteria in the Desulfovibrionaceae family. It is also an anaerobic sulfate-reducing bacterium that is an important organism involved in the bioremediation of heavy metals in the environment. ''Nitratidesulfovibrio vulgaris'' is often used as a model organism for sulfur-reducing bacteria and was the first of such bacteria to have its genome sequenced. It is ubiquitous in nature and has also been implicated in a variety of human bacterial infections, although it may only be an opportunistic pathogen. This microbe also has the ability to endure high salinity environments, which is done through the utilization of osmoprotectants and efflux systems. Description ''Nitratidesulfovibrio vulgaris'' is a sulfate-reducing bacterium (SRB) that plays an important role in cycling elements. The metabolism of SRBs contributes to bioremediation by increasing their pH. SRBs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
