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 ...

Dechloromonas Agitata
''Dechloromonas agitata'' strain CKB is a dissimilatory perchlorate reducing bacterium (DRPB) that was isolated from paper mill waste. Strain CKB is a Gram negative, facultative anaerobe belonging to the Betaproteobacteria. The cells of strain CKB are highly motile and possess a single polar flagellum. ''D. agitata'' can couple the oxidation of several electron donors such as acetate, propionate, butyrate, lactate, succinate, fumarate, malate or yeast extract to electron acceptors such as oxygen, chlorate, perchlorate, ferrous iron, sulphide, and reduced humic substances like 2,6-anthrahydroquinone disulphonate. Unlike other perchlorate reducers, strain CKB cannot grow by nitrate reduction, which suggests that the pathways of nitrate and perchlorate reduction are distinct and unrelated, contrary to what previous research had shown. Biological perchlorate reduction by strain CKB Strain CKB can reduce chlorate and perchlorate (collectively known as (per)chlorate) completely to chlo ...

-monas
The suffix -monas is used in microbiology for many genera and is intended to mean "unicellular organism". Meaning The suffix -monas found in many genera in microbiology is similar in usage to -bacter, -bacillus, -coccus or -spirillum. The genera with the suffix are not a monophyletic group and the suffix is chosen over -bacter, often simply out of stylistic preferences to match with Greek words. The first genus to be given the suffix -monas was ''Pseudomonas'', a genus of gammaproteobacteria. The generic epithet ''Pseudomonas'' was coined by Walter Migula in 1894, who did not give an etymology.Migula, W. (1900) System der Bakterien, Vol. 2. Jena, Germany: Gustav Fischer. Since the 7th edition of Bergey's manual (=top authority in bacterial nomenclature), other authors have given the etymology to be: Greek (, false) and (, single unit or monad), which can mean "false unit". However, "false unit" conceptually does not make much sense, namely, it does not mean "an organism which ...

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. ...

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 ...

Microbiology
Microbiology () is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Microbiologists traditionally relied on culture, staining, and microscopy. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means. Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example the 16S rRNA gene sequence used for bacteria identification. Viruses have been variably classified as organisms, as they have ...

Bacterial Taxonomy
Bacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria. In the scientific classification established by Carl Linnaeus, each species has to be assigned to a genus ( binary nomenclature), which in turn is a lower level of a hierarchy of ranks (family, suborder, order, subclass, class, division/phyla, kingdom and domain). In the currently accepted classification of life, there are three domains (Eukaryotes, Bacteria and Archaea), which, in terms of taxonomy, despite following the same principles have several different conventions between them and between their subdivisions as they are studied by different disciplines (botany, zoology, mycology and microbiology). For example, in zoology there are type specimens, whereas in microbiology there are type strains. Diversity Prokaryotes share many common features, such as lack of nuclear membrane, unicellularity, division by binary-fission and generally small size. The various species differ amongst each ot ...

Grammatical Gender
In linguistics, grammatical gender system is a specific form of noun class system, where nouns are assigned with gender categories that are often not related to their real-world qualities. In languages with grammatical gender, most or all nouns inherently carry one value of the grammatical category called ''gender''; the values present in a given language (of which there are usually two or three) are called the ''genders'' of that language. Whereas some authors use the term "grammatical gender" as a synonym of "noun class", others use different definitions for each; many authors prefer "noun classes" when none of the inflections in a language relate to sex. Gender systems are used in approximately one half of the world's languages. According to one definition: "Genders are classes of nouns reflected in the behaviour of associated words." Overview Languages with grammatical gender usually have two to four different genders, but some are attested with up to 20. #Gender contras ...

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 ...

Ancient Greek Language
Ancient Greek includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form a ...
