Actibacter
''Actibacter'' is a genus in the phylum Bacteroidota (Bacteria). The genus contains a single species, namely '' A. sediminis''. ''A. sediminis'' ''A. sediminis'', like other members of the phylum Bacteroidota, is Gram-negative and its major respiratory quinone is MK-6. Additionally, it grows aerobically and forms yellow-pigmented colonies which, however, do not contain Flexirubin-type pigments. This non-motile rod-shaped bacterium was isolated from tidal flat sediment of Dongmak on Ganghwa Island, South Korea. Etymology The name ''Actibacter'' derives from:Latin noun ''acta'', seaside; Neo-Latin masculine gender noun, a rod'' bacter'', nominally meaning "a rod", but in effect meaning a bacterium, rod; Neo-Latin masculine gender noun ''Actibacter'', rod from the seaside. While the epithet ''sediminis'' is from Latin genitive case noun ''sediminis'', of a sediment.

Flavobacteriaceae
Flavobacteriaceae is a family of rod-shaped gram negative bacteria. The family contains many environmental bacteria, with some species being potential pathogens. History The family of ''Flavobacteriaceae'' was first proposed by Reichenbach in 1989, it was approved by the IJSEM in 1992. The description of the family was emended several times in 1996 and 2002. In 2020, the family was split, with several genera moved to the newly established family of '' Weeksellaceae''. Biology Species of the ''Flavobacteriaceae'' are predominantly rod-shaped and stain gram-negative. Many species in the ''Flavobacteriaceae'' are motile, with most non-motile species formerly placed in the family now being placed in the '' Weeksellaceae''. Most species are aerobic, while some are microaerobic to anaerobic; for example '' Capnocytophaga'' and '' Coenonia''. Several members of the family are considered halophilic or psychrotolerant. The predominant respiratory quinone is menaquinone-6. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
-bacter
The suffix -bacter is used in microbiology for many genera and is intended to mean "bacteria". Meaning Bacter is a Neo-Latin (i.e. Modern Latin) term coined from bacterium, which in turn derives from the Greek ''βακτήριον'', meaning small staff (diminutive of βακτηρία). Consequently, it formally means "rod". It differs from the suffix ''-bacterium'' in grammatical gender, as the suffix ''-bacter'' is male, whereas the suffix ''-bacterium'') is neuter; this was decided in Juridical (or Judicial) Opinion n° 3 of the Bacteriological Code. Nevertheless, for historical reasons, two archaeal species finish in -bacter: '' Methanobrevibacter'' and '' Methanothermobacter''. Usage Juridical Opinion n° 2 in the Bacteriological Code discusses the declension of the word, given that authors differently assumed the genitive case of bacter to be ''bactris'' (3rd declension words of Latin origin ending in =ter), ''bacteri'' (2nd declension) or ''bacteris'' (3rd declension, us ...

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 ...

Grammatical Gender
In linguistics, a grammatical gender system is a specific form of a noun class system, where nouns are assigned to gender categories that are often not related to the real-world qualities of the entities denoted by those nouns. 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. Some authors use the term "grammatical gender" as a synonym of "noun class", whereas others use different definitions for each. Many authors prefer "noun classes" when none of the inflections in a language relate to Sex–gender distinction, sex or gender. According to one estimate, gender is used in approximately half of the world's languages. According to one definition: "Genders are classes of nouns reflected in the behavior of associated words."

Microbiology
Microbiology () is the branches of science, scientific study of microorganisms, those being of unicellular organism, unicellular (single-celled), multicellular organism, multicellular (consisting of complex cells), or non-cellular life, acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. The organisms that constitute the microbial world are characterized as either prokaryotes or eukaryotes; eukaryote, Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryote, prokaryotic organisms are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Microbiologists traditionally relied on culture, staining, and microscopy for the isolation and identification of microorganisms. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacterial Taxonomy
Bacterial taxonomy is subfield of taxonomy devoted to the classification of bacteria specimens into taxonomic ranks. Archaeal taxonomy are governed by the same rules. In the scientific classification established by Carl Linnaeus, each species is assigned to a genus resulting in a two-part name. This name denotes the two lowest levels in a hierarchy of ranks, increasingly larger groupings of species based on common traits. Of these ranks, domains are the most general level of categorization. Presently, scientists classify all life into just three domains, Eukaryotes, Bacteria and Archaea. Bacterial taxonomy is the classification of strains within the domain Bacteria into hierarchies of similarity. This classification is similar to that of plants, mammals, and other taxonomies. However, biologists specializing in different areas have developed differing taxonomic conventions over time. For example, bacterial taxonomists name types based on descriptions of strains.

Latin Declension
Latin declension is the set of patterns according to which Latin language, Latin words are Declension, declined—that is, have their endings altered to show grammatical case, Grammatical number, number and Grammatical gender, gender. Nouns, pronouns, and adjectives are declined (verbs are Grammatical conjugation, conjugated), and a given pattern is called a declension. There are five declensions, which are numbered and grouped by ending and grammatical gender. Each noun follows one of the five declensions, but some irregular nouns have exceptions. Adjectives are of two kinds: those like 'good' use first-declension endings for the feminine, and second-declension for masculine and neuter. Other adjectives such as belong to the third declension. There are no fourth- or fifth-declension adjectives. Pronouns are also of two kinds, the personal pronouns such as 'I' and 'you ()', which have their own irregular declension, and the third-person pronouns such as 'this' and 'that' wh ...

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest. Latin Root (linguistics), roots appear frequently in the technical vocabulary used by fields such as theology, List of Latin and Greek words commonly used in systematic names, the sciences, List of medical roots, suffixes and prefixes, medicine, and List of Latin legal terms ...

Neo-Latin
Neo-LatinSidwell, Keith ''Classical Latin-Medieval Latin-Neo Latin'' in ; others, throughout. (also known as New Latin and Modern Latin) is the style of written Latin used in original literary, scholarly, and scientific works, first in Italy during the Italian Renaissance of the fourteenth and fifteenth centuries, and then across northern Europe after about 1500, as a key feature of the humanist movement. Through comparison with Classical Latin, Latin of the Classical period, scholars from Petrarch onwards promoted a standard of Latin closer to that of the ancient Romans, especially in grammar, style, and spelling. The term ''Neo-Latin'' was however coined much later, probably in Germany in the late eighteenth century, as ''Neulatein'', spreading to French and other languages in the nineteenth century. Medieval Latin had diverged quite substantially from the classical standard and saw notable regional variation and influence from vernacular languages. Neo-Latin attempts to retur ...

Bacteroidota
The phylum (biology), phylum Bacteroidota (synonym Bacteroidetes) is composed of three large classes of Gram-negative bacteria, Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals. Although some ''Bacteroides'' spp. can be Opportunistic Pathogens, opportunistic pathogens, many ''Bacteroidota'' are Symbiotic bacteria, symbiotic species highly adjusted to the gastrointestinal tract. ''Bacteroides'' are highly abundant in intestines, reaching up to 1011 cells g−1 of intestinal material. They perform metabolic conversions that are essential for the host, such as degradation of proteins or complex sugar polymers. ''Bacteroidota'' colonize the gastrointestinal tract already in infants, as non-digestible Human milk oligosaccharide, oligosaccharides in mother milk support the growth of both ''Bacteroides'' and ''Bifidoba ...
