Coprothermobacter
''Coprothermobacter'' is a genus of rod-shaped microorganisms, belonging to the new bacterial family ''Coprothermobacteraceae'' of the new phylum ''Coprothermobacterota''. This taxonomic genus has been reclassified in 2018, after different phylogenetic studies showed that these bacteria represented a deeply branched taxon of the domain ''Bacteria''; consequently, the clade including this genus has been classified in a separate phylum from ''Firmicutes'', the phylum where it was included before reclassification. According to the first description of this genus, the etymology of its name derives from Greek words "''kopros''", meaning dung, from the source where one of the species ('' Coprothermobacter proteolyticus'') was isolated, and "''thermos''", meaning hot, warm, because of the relatively high temperatures at which these bacteria are able to grow, which can be as high as 75°C. Actually, very few known bacterial species are included in this genus, which are characterized by s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coprothermobacteraceae
Coprothermobacteraceae is a new bacterial family of rod-shaped microorganisms, belonging to the order Coprothermobacterales, class Coprothermobacteria of the new phylum Coprothermobacterota. The name of this family was given on the basis of an early genus identified within this group, dubbed "''Coprothermobacter''", whose etymology derives from Greek "''kopros''", meaning manure, and "''thermos''", warm, from the source where these bacteria were collected and the temperature conditions in which they are able to grow, which can be up to 75°C. This taxonomic family has been introduced in 2018, after a phylogenetic reclassification of the genus ''Coprothermobacter'', which has been based on published studies that shown that these bacteria actually represent a deeply branched taxon of the domain Bacteria. Consequently, the clade including this genus has been classified in the phylum Coprothermobacterota, a separate phylum from Firmicute', where ''Coprothermobacter ''Coprothermo ...

Coprothermobacterota
''Coprothermobacterota'' is a phylum of nonmotile, rod-shaped bacteria. Its members are strictly anaerobic and thermophilic, growing at optimal temperatures between 55 °C and 70 °C. The name of this phylum is based on an early genus, dubbed "'' Coprothermobacter''", a term whose etymology derives from the Greek words "''kopros''", meaning manure, and "''thermos''", warm, referring to the fact that these bacteria are capable of living at relatively high temperatures, with a maximum growth temperature of 75 °C. Notes In October 2021, the name of this phylum has been accepted as ''validly published'', according to the emendations of the rules of the International Code of Nomenclature of Prokaryotes The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P.

Coprothermobacter Platensis
''Coprothermobacter platensis'' is a species of moderately thermophilic and strictly anaerobic bacterium belonging to the family Coprothermobacteraceae within the phylum Coprothermobacterota. Like another species in the genus, '' Coprothermobacter proteolyticus'', these bacteria are proteolytic, enabling them to break down proteins in anaerobic conditions. In ''C. platensis'', this capability is related to the source from where this bacterium was firstly isolated, the sludge blanket of a methanogenic, mesophilic anaerobic reactor used for the treatment of protein-rich wastewater from a baker's yeast factory, in Uruguay (region bounded by the ''Rio de la Plata'' river, giving rise to the name ''"platensis"'' for this species, though this bacterium was not isolated from the river). The bacterial cells are straight, rod-shaped, about long and 0.5 μm in diameter, non-motile, non- spore-forming and stain Gram-negative Gram-negative bacteria are bacteria that do not retain ...

Coprothermobacter Proteolyticus
''Coprothermobacter proteolyticus'', formerly ''Thermobacteroides proteolyticus'', is a thermophilic, non- spore-forming bacteria. ''Coprothermobacter proteolyticus'' was originally isolated from a thermophilic digester that was fermenting tannery wastes and cattle manure. These bacteria are rod-shaped and stain Gram-negative, although the cell structure is Gram-positive. The growth range is 35 to 75 °C and pH 5.5 to 8.5, with the optimum growth conditions of 63 °C at pH 7.5. The species uses sugars poorly unless yeast extract and either rumen fluid or Tripticase peptone are available.Bernard M. Ollivier, Robert A. Mah, Thomas J. Ferguson, David R. Boone, J.L.

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), 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, Hot spring, 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 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, such as hydrogen sulp ...

Phylum
In biology, a phylum (; plural: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the term 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 8 phyla. Current research in phylogenetics is uncovering the relationships between phyla, which are contained in 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 distinguished them as a group ("a self-contained un ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Phylogenetics
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and do ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaea
Archaea ( ; singular archaeon ) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat, square cells of '' Haloquadratum walsbyi''. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes invo ...
