Caryophanon
The ''Caryophanaceae'' is a family of Gram-positive bacteria. In 2020, the now defunct family ''Planococcaceae'' was merged into ''Caryophanaceae'' to rectify a nomenclature anomaly. The type genus of this family is ''Caryophanon.'' The family ''Planococcacae'' was validly published in 1949, however it contained within it another family level taxonomic rank, the family ''Caryophanaceae,'' which was validly published in 1939. According to the International Code of Nomenclature of Prokaryotes (ICNP), the name ''Caryophanacaeae'' has higher priority than ''Planococcaceae'' because of its earlier publication. Therefore, the emended family retained the name ''Caryophanaceae''. The name ''Caryophanaceae'' is derived from the Latin term ''Caryophanon'', referring the type genus of the family and the suffix "-aceae", an ending used to denote a family. Together, ''Caryophanaceae'' refers to a family whose nomenclatural type is the genus ''Caryophanon''. Biochemical Characteristics an ...

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] |

Conserved Signature Indels
Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. CSIs, brought about by rare genetic changes, provide useful phylogenetic markers that are generally of defined size and they are flanked on both sides by conserved regions to ensure their reliability. While indels can be arbitrary inserts or deletions, CSIs are defined as only those protein indels that are present within conserved regions of the protein. The CSIs that are restricted to a particular clade or group of species, generally provide good phylogenetic markers of common evolutionary descent. Due to the rarity and highly specific nature of such changes, it is less likely that they could arise independently by either convergent or parallel evolution (i.e. homoplasy) and therefore are likely to represent synapomorphy. Other confounding factors such as differences in evolutionary rates at different sites or among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. H. A. Sneath, 2003. A short history of the Bacteriological CodURL It denotes the rules for naming taxa of bacteria, according to their relative rank. As such it is one of the nomenclature codes of biology. Originally the ''International Code of Botanical Nomenclature'' dealt with bacteria, and this kept references to bacteria until these were eliminated at the 1975 International Botanical Congress. An early Code for the nomenclature of bacteria was approved at the 4th International Congress for Microbiology in 1947, but was later discarded. The latest version to be printed in book form is the 1990 Revision, but the book does not represent the current rules. The 2008 Revision has been published in the ''International Journal of Systematic and Evolutionary Microbiology'' (I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gram-positive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells, making the cell wall more porous and incapable of retaining the crystal violet stain. Their peptidoglycan layer is much thinner and sandwiched between an inner cell membrane and a bacterial outer membrane, causing them to take up the counterstain (saf ...

Family (taxonomy)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Ureibacillus
''Ureibacillus'' is a genus of gram-negative bacteria within the largely gram-positive Bacillota. ''Ureibacilli'' are motile and form spherical endospores. The type species of the genus is '' Ureibacillus thermosphaericus''. History The genus ''Ureibacillus'' was split from the genus ''Bacillus'' in 2001 to encompass ''Bacillus thermosphaericus'' (now ''Ureibacillus thermosphaericus'') as well as several newly discovered similar strains of bacteria. In 2020, multiple ''Lysinibacillus'' species were transferred into ''Ureibacillus'' based on branching patterns in various phylogenetic trees constructed based on conserved genome sequences, indicating their phylogenetic relatedness. The family ''Caryophanaceae'' encompassed many branching anomalies such as this one, partially due to the reliance on 16S rRNA sequences as a method for classification, which is known to have low resolution power and give differing results depending on the algorithm used.

Sporosarcina
''Sporosarcina'' is a genus of bacteria. Specification The cells of the species of ''Sporosarcina'' are either rod-shaped or coccoid. ''Sporosarcina'' forms endospores. The majority species of ''Sporosarcina'' is moveable (motile). Metabolism All species of ''Sporosarcina'' are heterotrophic. They do not perform photosynthesis. A few species are obligate aerobic, they need oxygen. Others are facultative aerobic, they can also perform metabolism in the absence of oxygen. Ecology Some species, such as ''S. ureae'' have the enzyme urease and are thus able to break down urea. The species forms the highest population densities in soils that are subject to influence of urine. These include, for example, meadows where cattle are kept. Thus ''S. ureae'' plays an important role in the ecosystem. Molecular Signatures Analyses of genome sequences of ''Sporosarcina'' species identified eight conserved signature indels (CSIs) that are uniquely present in this genus in the protein ...

Solibacillus
''Solibacillus'' is a genus of Gram positive, rod shaped, spore-forming bacteria. The first member of ''Solibacillus'' was first isolated in 1999, and was originally called ''Bacillus silvestris''. However, further studies on ''B. silvestris'' found that the organism belonged in a separate genus. ''Solibacillus silvestris'' was proposed, referring to its original designation as a member of ''Bacillus'', and the fact that the species was first isolated from soil. ''Bacillus isronensis'' was later reclassified as ''Solibacillus isronensis''. ''S. isronensis'' was isolated from cryotubes that were used to collect air samples from high altitudes, and ''S. kalamii'' was found in an air filter from the International Space Station.Sielaff AC, Kumar RM, Pal D, Mayilraj S, Venkateswaran K.
