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 involved ...

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 ...

Halobacteria
Haloarchaea (halophilic archaea, halophilic archaebacteria, halobacteria) are a class of the Euryarchaeota, found in water saturated or nearly saturated with salt. Halobacteria are now recognized as archaea rather than bacteria and are one of the largest groups. The name 'halobacteria' was assigned to this group of organisms before the existence of the domain Archaea was realized, and while valid according to taxonomic rules, should be updated. Halophilic archaea are generally referred to as haloarchaea to distinguish them from halophilic bacteria. These microorganisms are among the halophile organisms, that they require high salt concentrations to grow, with most species requiring more than 2.0M NaCl for growth and survival. They are a distinct evolutionary branch of the Archaea distinguished by the possession of ether-linked lipids and the absence of murein in their cell walls. Haloarchaea can grow aerobically or anaerobically. Parts of the membranes of haloarchaea are purpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haloferacales
''Haloferacales'' is an order of halophilic, chemoorganotrophic or heterotrophic archaea within the class Haloarchaea. The type genus of this order is ''Haloferax.'' The name ''Haloferacales'' is derived from the Latin term ''Haloferax,'' referring to the type genus of the order and the suffix "-ales," an ending used to denote an order. Together, ''Haloferacales'' refers to an order whose nomenclatural type is the genus ''Haloferax.'' Biochemical Characteristics and Molecular Signatures Members are halophiles and can be chemoorganotrophs or heterotrophs and are isolated from high-salt environments such as marine solar salterns and the Dead Sea. Some members are motile and contain gas vesicles. Morphology is variable, including rod, coccus or flat square shapes. Members of this order grow optimally in neutral pH. The DNA G+C content for this order ranges between 55-66 mol%. This order can be reliably distinguished from other Halobacteria by the presence of five conserved signatu ...

Haloferacaceae
''Haloferacaceae'' is a family of halophilic, chemoorganotrophic or heterotrophic archaea within the order ''Haloferacales.'' The type genus of this family is ''Haloferax.'' Its biochemical characteristics are the same as the order ''Haloferacales.'' The name ''Haloferacaceae'' is derived from the Latin term ''Haloferax,'' referring to the type genus of the family and the suffix "-ceae", an ending used to denote a family. Together, ''Haloferacaceae'' refers to a family whose nomenclatural type is the genus ''Haloferax.'' Taxonomy and molecular signatures As of 2021, ''Haloferacaceae'' contains 10 validly published genera. This family can be molecularly distinguished from other Halobacteria by the presence of five conserved signature proteins (CSPs) and four conserved signature indels (CSIs) present in the following proteins: thermosome, ribonuclease BN and hypothetical proteins. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing i ... [...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, ...

Buan County
Buan County (''Buan-gun'') is a county in North Jeolla Province, South Korea. It is bounded by the city of Jeongeup on the east, the county of Gochang on the south, the city of Gimje on the north, and Yellow Sea on the west. Buan is divided into 1 ''eup'', 12 ''myeon'', and 510 ''ri''. Buan had a 2001 estimated population of 74,716 people and a 2018 population of 54,441 people with an area of 493.35 km2. Famous people from Buan include Joseon Dynasty kisaeng and poet, Yi Mae-chang. Like many rural areas in southern Korea, it has seen shrinking population with many younger people moving north to larger cities such as Seoul. This county should not be confused with Muan, the new capital of South Jeolla Province. History During the Samhan Period Buan County was called Mahan, and it was also called Jiban statelets among the 54 Mahan statelets. During the Beakjae Period there were two small localities: Gaehwa and Heunlyangmae. In B.C 757(16th year of King Gyeongdeok's regime), ...
