Amycolatopsis is a genus of high GC-content bacteria within the family Pseudonocardiaceae. The genus is known for producing many types of antibiotics, including
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).
The Chloroflexota are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
Polaromonas is a genus of Gram-negative bacteria from the family Comamonadaceae. Polaromonas species are psychrophiles.
Exiguobacterium is a genus of bacilli and a member of the low GC phyla of Bacillota. Collins et al. first described the genus Exiguobacterium with the characterization of E. aurantiacum strain DSM6208T from an alkaline potato processing plant. It has been found in areas covering a wide range of temperatures (-12 °C—55 °C) including glaciers in Greenland and hot springs in Yellowstone, and has been isolated from ancient permafrost in Siberia. This ability to survive in varying temperature extremes makes them an important area of study. Some strains in addition to dynamic thermal adaption are also halotolerant, can grow within a wide range of pH values (5-11), tolerate high levels of UV radiation, and heavy metal stress.
Hymenobacter algoricola is a species of bacteria first isolated from Victoria Upper Glacier, Antarctica on basal ice. It is a psychrotolerant, heterotrophic aerobe. It is notable for the prevalence of horizontal gene transfers in its evolution, possibly due to dormancy because of its habitat.
Hymenobacter antarcticus is a species of bacteria first isolated from Victoria Upper Glacier, Antarctica on basal ice. It is a psychrotolerant, heterotrophic aerobe. It is notable for the prevalence of horizontal gene transfers in its evolution, possibly due to dormancy because of its habitat.
Hymenobacter elongatus is a species of bacteria first isolated from Victoria Upper Glacier, Antarctica on basal ice. It is a psychrotolerant, heterotrophic aerobe. It is notable for the prevalence of horizontal gene transfers in its evolution, possibly due to dormancy because of its habitat.
Hymenobacter glaciei is a species of bacteria first isolated from Victoria Upper Glacier, Antarctica on basal ice. It is a psychrotolerant, heterotrophic aerobe. It is notable for the prevalence of horizontal gene transfers in its evolution, possibly due to dormancy because of its habitat.
Hymenobacter is a Gram-negative and non-motile bacterial genus from the family Hymenobacteraceae.
Hymenobacter arizonensis is a rod-shaped and non-motile bacterium from the genus Hymenobacter which has been isolated from biological soil crusts at the Colorado Plateau in the United States.
Hymenobacter qilianensis is a Gram-negative, rod-shaped, non-spore-forming and non-motile bacterium from the genus Hymenobacter which has been isolated from the permafrost region of Qilian Mountains in China.
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.
Dyadobacter is a genus of gram negative rod-shaped bacteria belonging to the family Spirosomaceae in the phylum Bacteroidota. Typical traits of the genus include yellow colony colour, positive flexirubin test and non-motile behaviours. They possess an anaerobic metabolism, can utilise a broad range of carbon sources, and test positive for peroxide catalase activity. The type species is Dyadobacter fermentans, which was isolated from surface sterilised maize leaves,.
Paraburkholderia is a genus of Pseudomonadota that are gram negative, slightly curved rods that are motile by means of flagella. They have been reported to colonize endophytic tissues of hybrid spruce and lodgepole pine with a strong potential to perform biological nitrogen fixation and plant growth promotion. Unlike Burkholderia species, Paraburkholderia members are not commonly associated with human infection. Paraburkholderia members form a monophyletic clade within the Burkholderiaceae family, which is what prompted their distinction as a genus independent from Burkholderia species, in combination with the finding of robust conserved signature indels which are unique to Paraburkholderia species, and are lacking in members of the genus Burkholderia. These CSIs distinguish the genus from all other bacteria. Additionally, the CSIs that were found to be shared by Burkholderia species are absent in Paraburkholderia, providing evidence of separate lineages.
Roseomonas ludipueritiae is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pale yellow-colored bacteria. It was first isolated from a children's day care center in 1995. Further work on the isolate led to the proposal of a new genus and species, Teichococcus ludipueritiae in 2003. Further work on T. ludipueritiae found that the species belonged in the genus Roseomonas, and also led to Muricoccus roseus being reclassified as Roseomonas rosea. The species name is derived from Latin ludus (garden) and pueritia (boyhood), referring to the kindergarten day care from which the species was first isolated.
Sinorhodobacter is a genus of bacteria from the family of Rhodobacteraceae.
Mariniflexile is a genus in the phylum Bacteroidota (Bacteria). The various species have been recovered from sea water, sea urchins, springs, brackish water, and an oyster.
Jejudonia is a Gram-negative, rod-shaped and non-motile genus of bacteria from the family of Flavobacteriaceae with one known species.
