Medical Subject Headings
Medical Subject Headings (MeSH) is a comprehensive controlled vocabulary for the purpose of indexing journal articles and books in the life sciences. It serves as a thesaurus that facilitates searching. Created and updated by the United States National Library of Medicine (NLM), it is used by the MEDLINE/PubMed article database and by NLM's catalog of book holdings. MeSH is also used by ClinicalTrials.gov registry to classify which diseases are studied by trials registered in ClinicalTrials. MeSH was introduced in the 1960s, with the NLM's own index catalogue and the subject headings of the Quarterly Cumulative Index Medicus (1940 edition) as precursors. The yearly printed version of MeSH was discontinued in 2007; MeSH is now available only online. It can be browsed and downloaded free of charge through PubMed. Originally in English, MeSH has been translated into numerous other languages and allows retrieval of documents from different origins. Structure MeSH vocabulary is divi ...

Haloferax
In taxonomy, ''Haloferax'' (common abbreviation: ''Hfx.'') is a genus of the Haloferacaceae. Genetic exchange Cells of ''H. mediterranei'' and cells of the related species '' H. volcanii'' can undergo a process of genetic exchange between two cells which involves cell fusion resulting in a heterodiploid cell (containing two different chromosomes in one cell). Although this genetic exchange ordinarily occurs between two cells of the same species, it can also occur at a lower frequency between an ''H. mediterranei'' and an ''H. volcani'' cell. These two species have an average nucleotide sequence identity of 86.6%. During this exchange process, a diploid cell is formed that contains the full genetic repertoire of both parental cells, and genetic recombination is facilitated. Subsequently, the cells separate, giving rise to recombinant cells. Taxonomy As of 2022, 13 species are validly published under the genus ''Haloferax''. ;Proposed species Several species and novel binomial ...

Halococcus
''Halococcus'' (common abbreviation: ''Hcc.'') is a genus (biology), genus of the Halococcaceae. Ecology ''Halococcus'' is a genus of extreme halophilic archaea, meaning that they require high salt levels, sometimes as high as 32% NaCl, for optimal growth. Halophiles are found mainly in inland bodies of water with high salinity, where their pigments (from a protein called rhodopsinprotein) tint the sediment bright colors. Rhodopsinprotein and other proteins serve to protect ''Halococcus'' from the extreme salinities of their environments. Because they can function under such high-salt conditions, ''Halococcus'' and similar halophilic organisms have been used in the food industry and even in skin-care products. ''Halococcus'' is found in environments with high salt levels, mainly inland bodies of salt water, but some may be located in highly salted soil or foods. The pigmented proteins in some species cause the reddish tint found in some areas of the Dead Sea and the Great Salt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halobacterium Salinarum
''Halobacterium salinarum'', formerly known as ''Halobacterium cutirubrum'' or ''Halobacterium halobium'', is an extremely halophilic marine obligate aerobic archaeon. Despite its name, this is not a bacterium, but a member of the domain Archaea. It is found in salted fish, hides, hypersaline lakes, and salterns. As these salterns reach the minimum salinity limits for extreme halophiles, their waters become purple or reddish color due to the high densities of halophilic Archaea. ''H. salinarum'' has also been found in high-salt food such as salt pork, marine fish, and sausages. The ability of ''H. salinarum'' to survive at such high salt concentrations has led to its classification as an extremophile. Cell morphology and metabolism Halobacteria are single-celled, rod-shaped microorganisms that are among the most ancient forms of life and appeared on Earth billions of years ago. The membrane consists of a single lipid bilayer surrounded by an S-layer. The S-layer is made of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halobacterium
''Halobacterium'' (common abbreviation ''Hbt.'') is a genus in the family Halobacteriaceae. The genus ''Halobacterium'' ("salt" or "ocean bacterium") consists of several species of Archaea with an aerobic metabolism which requires an environment with a high concentration of salt; many of their proteins will not function in low-salt environments. They grow on amino acids in their aerobic conditions. Their cell walls are also quite different from those of bacteria, as ordinary lipoprotein membranes fail in high salt concentrations. In shape, they may be either rods or cocci, and in color, either red or purple. They reproduce using binary fission (by constriction), and are motile. ''Halobacterium'' grows best in a 42 °C environment. The genome of an unspecified ''Halobacterium'' species, sequenced by Shiladitya DasSarma, comprises 2,571,010 bp (base pairs) of DNA compiled into three circular strands: one large chromosome with 2,014,239 bp, and two smaller ones with 191,346 an ...

Haloarcula
''Haloarcula'' (common abbreviation ''Har.'') is a genus of extreme halophilic Archaea in the class of Halobactaria. Cell Structure ''Haloarcula'' species can be distinguished from other genera in the family Halobacteriaceae by the presence of specific derivatives of TGD-2 polar lipids. ''H. quadrata'' has predominantly flat, square-shaped, somewhat pleomorphic cells. Metabolism ''H. quadrata'' was first isolated when researchers were attempting to culture ''Haloquadratum walsbyi'', a haloarchaeon that was thought to be unculturable until 2004. Similar to other halophilic archaea, ''Haloarcula'' species grow optimally at 40–45 °C. Growth appears in sheets of up to 65 cells often in the shape of a square or triangle. Taxonomy The genus of ''Haloarcula'' was long grouped with other halophilic archaea such as '' Halobacterium'' until genomic analysis prompted to reorder this genus in the new family of Haloarculaceae. Ecology ''Haloarcula'' species are found in neutral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halobacteriaceae
In taxonomy, the Halobacteriaceae are a family of the Halobacteriales in the domain Archaea.See the NCBIbr>webpage on Halobacteriaceae Data extracted from the ''Halobacteriaceae'' represent a large part of halophilic Archaea, along with members in two other methanogenic families, ''Methanosarcinaceae'' and ''Methanocalculaceae''. The family consists of many diverse genera that can survive extreme environmental niches. Most commonly, Halobacteriaceae are found in hypersaline lakes and can even tolerate sites polluted by heavy metals. They include neutrophiles, acidophiles (ex. ''Halarchaeum acidiphilum''), alkaliphiles (ex. ''Natronobacterium''), and there have even been psychrotolerant species discovered (ex. ''Hrr. lacusprofundi''). Some members have been known to live aerobically, as well as anaerobically, and they come in many different morphologies. These diverse morphologies include rods in genus Halobacterium, cocci in Halococcus, flattened discs or cups in Haloferax, ...

Halobacteriales
In taxonomy, the Halobacteriales are an order of the Halobacteria, found in water saturated or nearly saturated with salt. They are also called halophiles, though this name is also used for other organisms which live in somewhat less concentrated salt water. They are common in most environments where large amounts of salt, moisture, and organic material are available. Large blooms appear reddish, from the pigment bacteriorhodopsin. This pigment is used to absorb light, which provides energy to create ATP. Halobacteria also possess a second pigment, halorhodopsin, which pumps in chloride ions in response to photons, creating a voltage gradient and assisting in the production of energy from light. The process is unrelated to other forms of photosynthesis involving electron transport; however, and halobacteria are incapable of fixing carbon from carbon dioxide. Halobacteria can exist in salty environments because although they are aerobes they have a separate and different way o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeoglobus
''Archaeoglobus'' is a genus of the phylum Euryarchaeota. ''Archaeoglobus'' can be found in high-temperature oil fields where they may contribute to oil field souring. Metabolism ''Archaeoglobus'' grow anaerobically at extremely high temperatures between 60 and 95 °C, with optimal growth at 83 °C (ssp. ''A. fulgidus'' VC-16). They are sulfate-reducing archaea, coupling the reduction of sulfate to sulfide with the oxidation of many different organic carbon sources, including complex polymers. ''A. lithotrophicus'' live chemolitho-autotrophically from hydrogen, sulfate and carbon dioxide. Also ''A. profundus'' grow lithotrophically, but while this species needs acetate and CO2 for biosynthesis they are heterotroph. The complete ''A. fulgidus'' genome sequence revealed the presence of a nearly complete set of genes for methanogenesis. The function of these genes in ''A. fulgidus'' remains unknown, while the lack of the enzyme methyl-CoM reductase does not allow ...

Archaeoglobales
Archaeoglobaceae are a family of the Archaeoglobales. All known genera within the Archaeoglobaceae are hyperthermophilic and can be found near undersea hydrothermal vents. Archaeoglobaceae are the only family in the order ''Archaeoglobales'', which is the only order in the class ''Archaeoglobi''. Mode of metabolism While all genera within the Archaeoglobaceae are related to each other phylogenetically, the mode of metabolism used by each of these organisms is unique. ''Archaeoglobus'' are chemoorganotrophic sulfate-reducing archaea, the only known member of the Archaea that possesses this type of metabolism. '' Ferroglobus'', in contrast, are chemolithotrophic organisms that couple the oxidation of ferrous iron to the reduction of nitrate. '' Geoglobus'' are iron reducing-archaea that use hydrogen gas or organic compounds as energy sources. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and Natio ...

Euryarchaeota
Euryarchaeota (from Ancient Greek ''εὐρύς'' eurús, "broad, wide") is a phylum of archaea. Euryarchaeota are highly diverse and include methanogens, which produce methane and are often found in intestines, halobacteria, which survive extreme concentrations of salt, and some extremely thermophilic aerobes and anaerobes, which generally live at temperatures between 41 and 122 °C. They are separated from the other archaeans based mainly on rRNA sequences and their unique DNA polymerase. Description The ''Euryarchaeota'' are diverse in appearance and metabolic properties. The phylum contains organisms of a variety of shapes, including both rods and cocci. ''Euryarchaeota'' may appear either gram-positive or gram-negative depending on whether pseudomurein is present in the cell wall. ''Euryarchaeota'' also demonstrate diverse lifestyles, including methanogens, halophiles, sulfate-reducers, and extreme thermophiles in each. Others live in the ocean, suspended with plankton ...
