Myxococcus Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochensis
''Myxococcus '' is a gram-negative, rod-shaped species of myxobacteria found in soil. It is a predator on other bacteria. The ends of the rod-shaped vegetative cells taper slightly. The colonies are pale brown and show swarming motility. It produces orange, roughly spherical fruiting bodies. A draft sequence of its genome showed significant differences from all previously known species of the genus '' Myxococcus''. It was isolated from soil collected near the settlement of , on the island of Anglesey in North Wales, and was named after this location. The scientific name of this bacterial species is considered the longest name in the binomial nomenclature system, bearing 73 characters in total. Despite this, it is not yet acknowledged by the International Journal of Systematic and Evolutionary Microbiology (IJSEM), and therefore is not considered to be valid. The current longest valid scientific name is ''Parastratiosphecomyia stratiosphecomyioides ''Parastratiosphecomyia s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myxobacteria
The myxobacteria ("slime bacteria") are a group of bacteria that predominantly live in the soil and feed on insoluble organic substances. The myxobacteria have very large genomes relative to other bacteria, e.g. 9–10 million nucleotides except for '' Anaeromyxobacter'' and ''Vulgatibacter''. One species of myxobacteria, ''Minicystis rosea'', has the largest known bacterial genome with over 16 million nucleotides. The second largest is another myxobacteria ''Sorangium cellulosum''. Myxobacteria can move by gliding. They typically travel in ''swarms'' (also known as ''wolf packs''), containing many cells kept together by intercellular molecular signals. Individuals benefit from aggregation as it allows accumulation of the extracellular enzymes that are used to digest food; this in turn increases feeding efficiency. Myxobacteria produce a number of biomedically and industrially useful chemicals, such as antibiotics, and export those chemicals outside the cell. Myxobacteria are u ...

Swarming Motility
Swarming motility is a rapid (2–10 μm/s) and coordinated translocation of a bacterial population across solid or semi-solid surfaces, and is an example of bacterial multicellularity and swarm behaviour. Swarming motility was first reported by Jorgen Henrichsen and has been mostly studied in genus ''Serratia'', '' Salmonella'', '' Aeromonas'', ''Bacillus'', ''Yersinia'', ''Pseudomonas'', ''Proteus'', ''Vibrio'' and ''Escherichia''. This multicellular behavior has been mostly observed in controlled laboratory conditions and relies on two critical elements: 1) the nutrient composition and 2) viscosity of culture medium (i.e. % agar). One particular feature of this type of motility is the formation of dendritic fractal-like patterns formed by migrating swarms moving away from an initial location. Although the majority of species can produce tendrils when swarming, some species like ''Proteus mirabilis'' do form concentric circles motif instead of dendritic patterns. Biosurfactan ...

Myxococcus
''Myxococcus'' is a genus of bacteria in the family Myxococcaceae. Myxococci are Gram-negative, spore-forming, chemoorganotrophic, obligate aerobes. They are elongated rods with rounded or tapered ends, and they are nonflagellated. The cells move by gliding and can predate other bacteria. The genus has been isolated from soil. At least eleven species had been identified with confidence by late 2020 and each had been characterised to some extent. As well as using traditional biochemical tests, strains of some species had been compared using whole genome sequences. This approach has provided evidence that the genus, like most bacterial genera, has a core set of genes found in all members of the genus, along with others that are confined to particular species. The identity of ''Myxococcus'' species therefore continues to change. An example where taxonomy may be changed is that comparisons of genome sequences and biochemical tests indicated that '' M. xanthus'' and ''M. virescens'' ...

Llanfairpwllgwyngyll
Llanfairpwllgwyngyll, or Llanfair Pwllgwyngyll (), is a large village and local government community on the island of Anglesey, Wales, on the Menai Strait next to the Britannia Bridge and across the strait from Bangor. Both shortened (Llanfairpwll or Llanfair PG) and lengthened () forms of the placename are used in various contexts (with the longer form pronounced ). At the 2011 Census, the population was 3,107, of whom 71% could speak Welsh. It is the sixth largest settlement on the island by population. The long form of the name, with 58 characters split into 18 syllables, is purported to be the longest place name in Europe and the second longest one-word place name in the world. History There has been human activity and settlement in the area of the village since the Neolithic era (4000–2000 BC), with subsistence agriculture and fishing the most common occupations for much of its early history. The island of Anglesey was at that point reachable only by boat across ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglesey
Anglesey (; cy, (Ynys) Môn ) is an island off the north-west coast of Wales. It forms a principal area known as the Isle of Anglesey, that includes Holy Island across the narrow Cymyran Strait and some islets and skerries. Anglesey island, at , is the largest in Wales, the seventh largest in Britain, largest in the Irish Sea and second most populous there after the Isle of Man. Isle of Anglesey County Council administers , with a 2011 census population of 69,751, including 13,659 on Holy Island. The Menai Strait to the mainland is spanned by the Menai Suspension Bridge, designed by Thomas Telford in 1826, and the Britannia Bridge, built in 1850 and replaced in 1980. The largest town is Holyhead on Holy Island, whose ferry service with Ireland handles over two million passengers a year. The next largest is Llangefni, the county council seat. From 1974 to 1996 Anglesey was part of Gwynedd. Most full-time residents are habitual Welsh speakers. The Welsh name Ynys M ...

Parastratiosphecomyia Stratiosphecomyioides
''Parastratiosphecomyia stratiosphecomyioides'' is a species of fly in the family Stratiomyidae. It is native to Thailand.Woodley, Norman E. 2012. Revision of the southeast Asian soldier-fly genus Parastratiosphecomyia Brunetti, 1923 (Diptera, Stratiomyidae, Pachygastrinae) Zookeys 238: 1–21. Its genus name comes from Ancient Greek, meaning "Near soldier wasp-fly", with its species name meaning "wasp fly-like". It is considered to be the animal with the longest valid scientific name; the name ''Gammaracanthuskytodermogammarus loricatobaicalensis'' was longer, but was suppressed and is no longer valid. The proposed name for the bacterium '' Myxococcus '' is longer, but it is not an animal, and under the rules of nomenclature for bacteria, the name still must be published in the International Journal of Systematic and Evolutionary Microbiology (IJSEM) before it is accepted as valid. ''P. stratiosphecomyioides'', sometimes referred to as the Southeast Asian soldier fly, was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
