List Of Prokaryotic Names With Standing In Nomenclature
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy of prokaryotes, following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes. The database was curated from 1997 to June 2013 by Jean P. Euzéby. From July 2013 to January 2020, LPSN was curated by Aidan C. Parte. In February 2020, a new version of LPSN was published as a service of the Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service and since 2022 LPSN is interconnected with the Type (Strain) Genome Server (TYGS), DSMZ's high-throughput platform for accurate genome-based taxonomy.

Gram-negative
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic) membrane and an outer membrane. These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism '' Escherichia coli'', along with various pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They pose significant challenges in the medical field due to their outer membrane, which acts as a protective barrier against numerous antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and the antimicrobial enzyme lysozyme produced by animals as part of their innate immune system.

Oxidase
In biochemistry, an oxidase is an oxidoreductase (any enzyme that catalyzes a redox reaction) that uses dioxygen (O2) as the electron acceptor. In reactions involving donation of a hydrogen atom, oxygen is reduced to water (H2O) or hydrogen peroxide (H2O2). Some oxidation reactions, such as those involving monoamine oxidase or xanthine oxidase, typically do not involve free molecular oxygen. The oxidases are a subclass of the oxidoreductases. The use of dioxygen is the only unifying feature; in the EC classification, these enzymes are scattered in many categories. Examples An important example is EC 7.1.1.9 cytochrome c oxidase, the key enzyme that allows the body to employ oxygen in the generation of energy and the final component of the electron transfer chain. Other examples are: * EC 1.1.3.4 Glucose oxidase * EC 1.4.3.4 Monoamine oxidase * EC 1.14.-.- Cytochrome P450 oxidase * EC 1.6.3.1 NADPH oxidase * EC 1.17.3.2 Xanthine oxidase * EC 1.1.3.8 L-gulonolactone oxidase * EC 1. ...

Spore
In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the Biological life cycle, life cycles of many plants, algae, fungus, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. In some rare cases, a diploid spore is also p ...

Non-motile Bacteria
Non-motile bacteria are bacteria species that lack the ability and structures that would allow them to propel themselves, under their own power, through their environment. When non-motile bacteria are cultured in a stab tube, they only grow along the stab line. If the bacteria are mobile, the line will appear diffuse and extend into the medium. The cell structures that provide the ability for locomotion are the cilia and flagella. Coliform and Streptococci are examples of non-motile bacteria as are ''Klebsiella pneumoniae'', and ''Yersinia pestis''. Motility is one characteristic used in the identification of bacteria and evidence of possessing structures: peritrichous flagella, polar flagella and/or a combination of both. Though the lack of motility might be regarded a disadvantage, some non-motile bacteria possess structures that allow their attachment to eukaryotic cells The eukaryotes ( ) constitute the domain of Eukaryota or Eukarya, organisms whose cells have a ...

Brucella
''Brucella'' is a genus of Gram-negative bacterium, bacteria, named after David Bruce (microbiologist), David Bruce (1855–1931). They are small (0.5 to 0.7 by 0.6 to 1.5 μm), non-Bacterial capsule, encapsulated, non-motile, facultatively intracellular coccobacillus, coccobacilli. ''Brucella'' spp. are the cause of brucellosis, which is a zoonosis transmitted by ingesting contaminated food (such as Pasteurization, unpasteurized milk products), direct contact with an infected animal, or inhalation of aerosols. Transmission from human to human, for example, through sexual intercourse, or from mother to child, is exceedingly rare, but possible. Minimum infectious exposure is between 10 and 100 organisms. The different species of ''Brucella'' are genetically very similar, although each has a slightly different host specificity. Hence, the National Center for Biotechnology Information taxonomy includes most ''Brucella'' species under ''B. melitensis''. The many names of brucel ...

Gothenburg
Gothenburg ( ; ) is the List of urban areas in Sweden by population, second-largest city in Sweden, after the capital Stockholm, and the fifth-largest in the Nordic countries. Situated by the Kattegat on the west coast of Sweden, it is the gubernatorial seat of Västra Götaland County, with a population of approximately 600,000 in the city proper and about 1.1 million inhabitants in Metropolitan Gothenburg, the metropolitan area. Gustavus Adolphus, King Gustavus Adolphus founded Gothenburg by royal charter in 1621 as a heavily fortified, primarily Dutch, trading colony. In addition to the generous privileges given to his Dutch allies during the ongoing Thirty Years' War, e.g. tax relaxation, he also attracted significant numbers of his German and Scottish allies to populate his only town on the western coast; this trading status was furthered by the founding of the Swedish East India Company. At a key strategic location at the mouth of the , where Scandinavia's largest dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyphomicrobiales
The Hyphomicrobiale' (synonym Rhizobiales) are an order of Gram-negative Alphaproteobacteria. The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families. The four families '' Nitrobacteraceae'', '' Hyphomicrobiaceae'', '' Phyllobacteriaceae'', and '' Rhizobiaceae'' contain at least several genera of nitrogen-fixing, legume-nodulating, microsymbiotic bacteria. Examples are the genera '' Bradyrhizobium'' and ''Rhizobium''. Species of the '' Methylocystaceae'' are methanotrophs; they use methanol (CH3OH) or methane (CH4) as their sole energy and carbon sources. Other important genera are the human pathogens '' Bartonella'' and ''Brucella'', as well as ''Agrobacterium,'' an important tool in genetic engineering.
