Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of 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 soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of 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, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudomonadota
Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as ''Escherichia'', '' Salmonella'', ''Vibrio'', ''Yersinia'', ''Legionella'', and many others.Slonczewski JL, Foster JW, Foster E. Microbiology: An Evolving Science 5th Ed. WW Norton & Company; 2020. Others are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation. Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". Because of the great diversity of forms found in this group, it was later informally named Proteobacteria, after Proteus, a Greek god of the sea capable of assuming many different shapes (not after the Proteobacteria genus ''Proteus''). In 2021 the Internat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betaproteobacteria
Betaproteobacteria are a class of Gram-negative bacteria, and one of the eight classes of the phylum Pseudomonadota (synonym Proteobacteria). The ''Betaproteobacteria'' are a class comprising over 75 genera and 400 species of bacteria. Together, the ''Betaproteobacteria'' represent a broad variety of metabolic strategies and occupy diverse environments from obligate pathogens living within host organisms to oligotrophic groundwater ecosystems. Whilst most members of the ''Betaproteobacteria'' are heterotrophic, deriving both their carbon and electrons from organocarbon sources, some are photoheterotrophic, deriving energy from light and carbon from organocarbon sources. Other genera are autotrophic, deriving their carbon from bicarbonate or carbon dioxide and their electrons from reduced inorganic ions such as nitrite, ammonium, thiosulfate or sulfide — many of these chemolithoautotrophic. ''Betaproteobacteria'' are economically important, with roles in maintaining soil p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodocyclales
The ''Rhodocyclales'' are an order of the class ''Betaproteobacteria'' in the phylum "'' Pseudomonadota''".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. . Following a major reclassification of the class in 2017, the previously monofamilial order was split into three families: *'' Rhodocyclaceae'' ( type family) contains the genera '' Rhodocyclus'' (type genus), '' Azospira'' and '' Propionivibrio''. Cells are curved rods, rings or spirillae. Dominant respiratory quinones are menaquinone-8, ubiquinone-8 and rhodoquinone-8. G+C fractions are 61.6 - 65.3 mol%. *'' Azonexaceae'' contains the genera '' Azonexus'' (type genus), '' Dechloromonas'', '' Ferribacterium'' and '' Quatrionicoccus''. Cells are curved rods or cocci. Dominant respiratory quinone is ubiquinone-8. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodocyclaceae
The ''Rhodocyclaceae'' are a family of gram-negative bacteria.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. . They are given their own order in the beta subgroup of Pseudomonadota, and include many genera previously assigned to the family ''Pseudomonadaceae''. The family was revised in 2017 with the creation of other families within the order ''Rhodocyclales'', and the family now contains the genera: *'' Rhodocyclus'' (type genus) species can grow photoheterotrophically or photoautotrophically (using molecular hydrogen as their electron donor) under anoxia or heterotrophically on fatty acids under air. Dominant respiratory quinone is rhodoquinone-8. Cells are curved rods or rings. *'' Propionivibrio'' species grow anaerobically by fermentation of hydrocarbons, yielding f ...

Dechloromonas
''Dechloromonas'' is a genus in the phylum Pseudomonadota (Bacteria). Etymology The name ''Dechloromonas'' derives from:Latin pref. ''de'', from; New Latin noun ''chlorinum'' (from Greek adjective ''chlorōs'', green), chlorine; New Latin pref. ''chloro''-, pertaining to chlorine; Latin feminine gender noun '' monas (μονάς)'', unit, monad; New Latin feminine gender noun ''Dechloromonas'', a dechlorinating monad. Members of the genus Dechloromonas can be referred to as dechloromonads (''viz.'' Trivialisation of names). Species The genus contains 4 species, namely * '' D. agitata'' ( Achenbach ''et al''. 2001, (Type species of the genus).; Latin feminine gender participle adjective ''agitata'', excited, agitated, highly active.) * '' D. aromatica''( Cavalier-Smith 2002) * '' D. denitrificans'' ( Horn ''et al''. 2005, ; New Latin participle adjective ''denitrificans'', denitrifying.) * '' D. hortensis'' ( Wolterink ''et al''. 2005, ; Latin feminine gender adjective ''horten ...

Gram Negative
The gram (originally gramme; SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one one thousandth of a kilogram. Originally defined as of 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre the_temperature_of_Melting_point.html" "title="Melting_point_of_water.html" ;"title="Cubic_centimetre.html" ;"title=" Cubic centimetre">cm3], and at Melting point of water">the temperature of Melting point">melting ice", the defining temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water. However, by the late 19th century, there was an effort to make the Base unit (measurement), base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a ''gram'' as one one-thousandth of a kilogram (i.e., one gram is Scientific notation, 1×10−3 kg). The kilogram, as of 2019, is defined by the International Bur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flagellum
A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates. A microorganism may have from one to many flagella. A gram-negative bacterium ''Helicobacter pylori'' for example uses its multiple flagella to propel itself through the mucus lining to reach the stomach epithelium, where it may cause a gastric ulcer to develop. In some bacteria the flagellum can also function as a sensory organelle, being sensitive to wetness outside the cell. Across the three domains of Bacteria, Archaea, and Eukaryota the flagellum has a different structure, protein composition, and mechanism of propulsion but shares the same function of providing motility. The Latin word means " whip" to describe its lash-like swimming motion. The flagellum in archaea is called the archaellum to note its difference from the bacterial flagellum. Eukaryotic ...

Aporrectodea Caliginosa
''Aporrectodea caliginosa'' (also known as ''Allolobophora similis'' or the grey worm) is an earthworm commonly found in Great Britain. It is recognizable by the three distinct shades of colour at its front end, and it is in length when not moving. Its saddle pads usually form a two humped ridge across three segments along the length of the saddle, however this is not clearly visible. The worm mostly lies in non-permanent horizontal burrows in topsoil, and is rarely found in leaf litter Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent .... Like most worms, its diet consists only of soil. References Bart S, Amosse J, Lowe CN, Mougin C, Pery ARR, Pelosi C.
