Brachybacterium Paraconglomeratum
''Brachybacterium paraconglomeratum'' is a species of Gram positive, facultatively anaerobic, pale brown pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. The species was identified when a strain of '' Brachybacterium faecium'' was found to be a different species of ''Brachybacterium''. The name is derived from Latin ''para'' (alongside of, resembling) and ''conglomeratum'' (rolled together). ''B. paraconglomeratum'' resembles '' Brachybacterium conglomeratum'' phenotypically, and but are separate species based on DNA–DNA hybridization In genomics, DNA–DNA hybridization is a molecular biology technique that measures the degree of genetic similarity between DNA sequences. It is used to determine the genetic distance between two organisms and has been used extensively in phylo .... ''B. paraconglomeratum'' and ''B. conglomeratum'' were first proposed as species in the same paper in 1995, along with '' B. ...

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. The Gram stain is used by microbiologists to place bacteria into two main categories, gram-positive (+) and gram-negative (−). Gram-positive bacteria have a thick layer of peptidoglycan within the cell wall, and gram-negative bacteria have a thin layer of peptidoglycan. Gram-positive bacteria retain the crystal violet stain used in the test, resulting in a purple color when observed through an optical microscope. The thick layer of peptidoglycan in the bacterial cell wall retains the stain after it has been fixed in place by iodine. During the decolorization step, the decolorizer removes crystal violet from all other cells. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage deg ...

Bacterium
Bacteria (; : 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 the air, soil, water, 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 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 mutualistic, commensal and ...

Brachybacterium Faecium
''Brachybacterium faecium'' is a species of Gram positive, facultatively anaerobic bacterium. Colony pigmentation is grey, white, or pale yellow. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from poultry deep litter in 1966. The species was the first proposed for genus ''Brachybacterium'' in 1988, and is the type strain for the genus. The name is derived from the Latin Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages.

''faecium'' (dregs of feces), referring to the poultry litter from which it was first isolated.

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.

Brachybacterium Conglomeratum
''Brachybacterium conglomeratum'' is a species of Gram positive, facultatively anaerobic, whitish yellow to pale brown pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. The species was originally classified as ''Micrococcus conglomeratus'' for over 60 years,Sanborn JRCertain relationships of marine bacteria to the decomposition of fish.Journal of Bacteriology. 1930 Jun;19(6):375. until most species were reclassified as ''Brachybacterium conglomeratum'' in 1995.

Phenotype
In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological properties, and its behavior. An organism's phenotype results from two basic factors: the expression of an organism's genetic code (its genotype) and the influence of environmental factors. Both factors may interact, further affecting the phenotype. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic. A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 and again in his 1982 book '' The Extended Phenotype'' suggested that one can regard bird nests and other built structures such as caddisfly larva cases and beaver dams ...

DNA–DNA Hybridization
In genomics, DNA–DNA hybridization is a molecular biology technique that measures the degree of genetic similarity between DNA sequences. It is used to determine the genetic distance between two organisms and has been used extensively in phylogeny and taxonomy. Method The DNA of one organism is labelled, then mixed with the unlabelled DNA to be compared against. The mixture is incubated to allow DNA strands to dissociate and then cooled to form renewed hybrid double-stranded DNA. Hybridized sequences with a high degree of similarity will bind more firmly, and require more energy to separate them. An example is they separate when heated at a higher temperature than dissimilar sequences, a process known as " DNA melting". To assess the melting profile of the hybridized DNA, the double-stranded DNA is bound to a column or filter and the mixture is heated in small steps. At each step, the column or filter is washed; then sequences that melt become single-stranded and wash off. T ...

Brachybacterium Rhamnosum
''Brachybacterium rhamnosum'' is a species of Gram positive, facultatively anaerobic, whitish yellow-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from corn steep liquor, and the species was proposed in 1995 along with '' Brachybacterium conglomeratum'' and '' B. paraconglomeratum''. The name is derived from the fact that there is an abundance of the sugar rhamnose in the cell wall A cell wall is a structural layer that surrounds some Cell type, cell types, found immediately outside the cell membrane. It can be tough, flexible, and sometimes rigid. Primarily, it provides the cell with structural support, shape, protection, ....
