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 ...

Campylobacterota
Campylobacterota are a phylum of Gram-negative bacteria. Taxonomy Until the 2021 revision of bacterial taxonomy by the ICSP, the entire phylum was classified within the Proteobacteria (synonym Pseudomonadota) as the Epsilonproteobacteria and the Desulfurellales. The separation of this phylum from "Proteobacteria" was originally proposed in 2017, using GTDB-based methods. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).

Campylobacteria
The Campylobacteria are a class of Gram-negative bacteria. It used to be known as Epsilonproteobacteria. Only a few genera have been characterized, including the curved to spirilloid ''Wolinella'', ''Helicobacter'', and ''Campylobacter''. Most of the known species inhabit the digestive tracts of animals and serve as symbionts (''Wolinella'' spp. in cattle) or pathogens (''Helicobacter'' spp. in the stomach, ''Campylobacter'' spp. in the duodenum). However, numerous environmental sequences and isolates of Campylobacteria have been recovered from hydrothermal vents and cold seep habitats. Examples of isolates include '' Sulfurimonas autotrophica'', '' Sulfurimonas paralvinellae'', '' Sulfurovum lithotrophicum'' and '' Nautilia profundicola''. A member of the phylum Campylobacterota occurs as an endosymbiont in the large gills of the deepwater sea snail '' Alviniconcha hessleri''. Many Campylobacteria are motile with flagella. The Campylobacteria found at deep-sea hydrothermal ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campylobacterales
The Campylobacterales are an order of Campylobacterota which make up the epsilon subdivision, together with the small family Nautiliaceae. They are Gram-negative. Most of the species are microaerophilic.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. . Molecular signatures Comparative genomic analysis has led to the identification of 49 proteins which are uniquely found in virtually all species of the order Campylobacterales. Additionally, two conserved signature indels have been identified which, along with the proteins, serve as molecular markers for the order. The indels are a three-amino-acid insertion in the B protein of the Uvr ABC system, and a two-amino-acid deletion in phenylalanyl-tRNA synthetase.Gupta, R. S. (2006).

Sulfurospirillum
''Sulfurospirillum'' (Help:IPA/English, /ˌsʌlfɜːroʊspɪˈrɪlʌm/ Help:Pronunciation respelling key, ''SULF-ur-oh-spə-RIHL-um'') is a genus of the Gram-negative bacteria, gram-negative, Aerotolerant anaerobe, aerotolerant, rod-shaped bacteria in the family Campylobacterales, Campylobactaeraceae. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) Unassigned ''Sulfurospirillum'' species: * "''S. carboxydovorans''" Jensen & Finster 2005 * "''S. tacomaensis''" Pietari 2002 Details Many species are Microaerophile, microaerophillic, and are thus found in soil, groundwater, the deep sea, marine surface sediments, Osedax, tube worm guts, and polluted environments. Many species can grow on toxic compounds such as arsenate and selenate, and in fact flourish in contaminated sites. The ''Sulfurospirillum'' genus contains the only species on the planet tha ...

International Journal Of Systematic Bacteriology
The ''International Journal of Systematic and Evolutionary Microbiology'' is a peer-reviewed scientific journal covering research in the field of microbial systematics that was established in 1951. Its scope covers the taxonomy, nomenclature, identification, characterisation, culture preservation, phylogeny, evolution, and biodiversity of all microorganisms, including prokaryotes, yeasts and yeast-like organisms, protozoa and algae. The journal is currently published monthly by the Microbiology Society. An official publication of the International Committee on Systematics of Prokaryotes (ICSP) and International Union of Microbiological Societies (Bacteriology and Applied Microbiology Division), the journal is the single official international forum for the publication of new species names for prokaryotes.

Arsenic
Arsenic is a chemical element; it has Symbol (chemistry), symbol As and atomic number 33. It is a metalloid and one of the pnictogens, and therefore shares many properties with its group 15 neighbors phosphorus and antimony. Arsenic is notoriously toxic. It occurs naturally in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. It has various Allotropes of arsenic, allotropes, but only the grey form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is also a common n-type dopant in semiconductor electronic devices, and a component of the III–V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the persistent tox ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
