The Thermomicrobia is a group of thermophilic green non-sulfur bacteria. Based on species Thermomicrobium roseum and Sphaerobacter thermophilus, this bacteria class has the following description:
The Thermotogota are a phylum of the domain Bacteria. The phylum Thermotogota is composed of Gram-negative staining, anaerobic, and mostly thermophilic and hyperthermophilic bacteria.
Erysipelothrix is a genus of bacteria containing four described species, Erysipelothrix rhusiopathiae, Erysipelothrix tonsillarum, Erysipelothrix inopinata and Erysipelothrix larvae. Additional species have been proposed based on DNA-DNA hybridization studies "The hallmark of Erysipelothrix is the presence of a type B cell wall, in which the peptide bridge is formed between amino acids at positions 2 and 4 of adjacent peptide side-chains and not, as in the vast majority of bacteria, between amino acids at positions 3 and 4."
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.
Blood Falls is an outflow of an iron oxide–tainted plume of saltwater, flowing from the tongue of Taylor Glacier onto the ice-covered surface of West Lake Bonney in the Taylor Valley of the McMurdo Dry Valleys in Victoria Land, East Antarctica.
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 fastidiosus 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.
Chryseobacterium polytrichastri is a Gram-negative, rod-shaped and non-spore-forming bacteria from the genus Chryseobacterium which has been isolated from the moss Polytrichastrum formosum from the Gawalong glacier from Tibet in China.
Hymenobacter is a Gram-negative and non-motile bacterial genus from the family Hymenobacteraceae.
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.
Hymenobacter swuensis is a Gram-negative and non-motile bacterium from the genus Hymenobacter which has been isolated from mountain soil.
Roseomonas is a genus of Gram negative bacteria. The cells are coccoid rods when viewed microscopically. Certain species are known to be opportunistic infections for humans.
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.
