Living organisms are known by scientific names. These binomial names can vary greatly in length, and some of them can become very long depending on the meanings they try to convey. This list of longest species names lists the longest scientific binomials. [1] Species in this list are grouped by length of their name. Only binomials are considered, not subgenera, trinomial names of subspecies or infraspecific names. Family is given for each species (or the closest taxonomic rank if family is unassigned), with a short explanation. The shortest scientific species names can be found in the List of short species names.
Halomonadaceae is a family of halophilic Pseudomonadota.
Thermithiobacillus is a genus of nonsporeforming, rod-shaped, Gram-negative bacteria. The name derives from the Latin thermae, for warm baths, and the Classical Greek θείος, theios for sulfur. The type species of this genus was previously assigned to the genus Thiobacillus, but it was reclassified on the basis of 16S rRNA analysis in 2000, creating this genus.
The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
In taxonomy, Methanomethylovorans is a genus of microorganisms with the family Methanosarcinaceae. This genus was first described in 1999. The species within it generally live in freshwater environments, including rice paddies, freshwater sediments and contaminated soil. They produce methane from methanol, methylamines, dimethyl sulfide and methanethiol. With the exception of M. thermophila, which has an optimal growth temperature of 50 °C, these species are mesophiles and do not tend to grow at temperatures above 40 °C.
The Synergistota is a phylum of anaerobic bacteria that show Gram-negative staining and have rod/vibrioid cell shape. Although Synergistota have a diderm cell envelope, the genes for various proteins involved in lipopolysaccharides biosynthesis have not yet been detected in Synergistota, indicating that they may have an atypical outer cell envelope. The Synergistota inhabit a majority of anaerobic environments including animal gastrointestinal tracts, soil, oil wells, and wastewater treatment plants and they are also present in sites of human diseases such as cysts, abscesses, and areas of periodontal disease. Due to their presence at illness related sites, the Synergistota are suggested to be opportunistic pathogens but they can also be found in healthy individuals in the microbiome of the umbilicus and in normal vaginal flora. Species within this phylum have also been implicated in periodontal disease, gastrointestinal infections and soft tissue infections. Other species from this phylum have been identified as significant contributors in the degradation of sludge for production of biogas in anaerobic digesters and are potential candidates for use in renewable energy production through their production of hydrogen gas. All of the known Synergistota species and genera are presently part of a single class (Synergistia), order (Synergistiales), and family (Synergistaceae).
Arcanobacterium is a genus of bacteria. They are gram-positive, non–acid fast, nonmotile, facultatively anaerobic, and non–endospore forming. They are widely distributed in nature in the microbiota of animals and are mostly innocuous. Some can cause disease in humans and other animals. As with various species of a microbiota, they usually are not pathogenic but can occasionally opportunistically capitalize on atypical access to tissues or weakened host defenses.
Companilactobacillus kimchii is a bacteriocin-producing lactic acid bacterium of the genus Companilactobacillus. It is named for and found in the Korean fermented-vegetable food kimchi.
Deinococcus is in the monotypic family Deinococcaceae, and one genus of three in the order Deinococcales of the bacterial phylum Deinococcota highly resistant to environmental hazards. These bacteria have thick cell walls that give them Gram-positive stains, but they also include a second membrane and are therefore closer in structure to Gram-negative bacteria. Deinococcus survive when their DNA is exposed to high doses of gamma and UV radiation. Whereas other bacteria change their structure in the presence of radiation, such as by forming endospores, Deinococcus tolerate it without changing their cellular form and do not retreat into a hardened structure. They are also characterized by the presence of the carotenoid pigment deinoxanthin that give them their pink color. They are usually isolated according to these two criteria. In August 2020, scientists reported that bacteria from Earth, particularly Deinococcus bacteria, were found to survive for three years in outer space, based on studies conducted on the International Space Station. These findings support the notion of panspermia, the hypothesis that life exists throughout the Universe, distributed in various ways, including space dust, meteoroids, asteroids, comets, planetoids or contaminated spacecraft.
Caldithrix is a genus of thermophilic and anaerobic bacteria, currently assigned to its own phylum.
Polynucleobacter is a genus of bacteria, originally established by Heckmann and Schmidt (1987) to exclusively harbor obligate endosymbionts of ciliates belonging to the genus Euplotes.
Caballeronia grimmiae is a gram-negative, non-spore-forming, rod-shaped bacterium from the genus of Caballeronia and the family of Burkholderiaceae which was isolated from the xerophilous moss Grimmia montana in China.
Erythrobacteraceae is a bacterium family in the order of Sphingomonadales.
The Coriobacteriia are a class of Gram-positive bacteria within the Actinomycetota phylum. Species within this group are nonsporulating, strict or facultative anaerobes that are capable of thriving in a diverse set of ecological niches. Gordonibacter species are the only members capable of motility by means of flagella within the class. Several species within the Coriobacteriia class have been implicated with human diseases that range in severity. Atopobium, Olsenella, and Cryptobacterium species have responsible for human oral infections including periodontitis, halitosis, and other endodontic infections. Eggerthella species have been associated with severe blood bacteraemia and ulcerative colitis.
Weissella bombi is a bacterium from the genus of Weissella which has been isolated from the gut of the bumblebee Bombus terrestris from Ghent in Belgium.
Weissella diestrammenae is a Gram-positive, facultatively anaerobic and non-motile bacterium from the genus of Weissella which has been isolated from the gut of the camel cricket Diestrammena coreana in Korea.
Apilactobacillus is a genus of bacteria from the family of Lactobacillaceae.
Emcibacteraceae is a family of bacteria.
The Temperatibacteraceae are a family of bacteria.
Thermoleophilum is a genus of Actinomycetota.
The Ignavibacteriales are an order of obligately anaerobic, non-photosynthetic bacteria that are closely related to the green sulfur bacteria.
