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 (oxidase positive), 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, (apparently named after its ability to ferment glucose and fructose). [2]

Species of Dyadobacter have been isolated from a diverse range of environments worldwide, including glacial ice, seawater and factories, however a large number of the currently described species belonging to the genus Dyadobacter have been isolated from soil communities. [3] [4] [5] [6] Several studies observing the microbiome associated with plants have identified Dyadobacter species. These studies have recognized Dyadobacter strains from microbiomes of corn, potato, canola, wheat and Arabidopsis thaliana. [7] [8] [9] In some cases, Dyadobacter isolates have been shown to be one of the major cohorts of bacteria on plant phyllospheres. [10] [11] It is currently unknown what role Dyadobacter species play in these plant-associated communities.

Several species of Dyadobacter have been identified as potentially useful in bioremediation. Dyadobacter beijingensis was identified in a hydrocarbonoclastic community of bacteria remediating soil contaminated with crude oil, [12] and Strains of D. fermentans have been observed degrading 7,8-Benzoquinoline, an azaarene with mutagenic properties.

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).

<i>Arcanobacterium</i> Genus of bacteria

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.

<i>Deinococcus</i> Genus of bacteria

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 include a second membrane and so are 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.

Pedobacter terricola is a species of Gram-negative, non-motile, pleomorphic bacteria. Its type strain is DS-45(T).

Thorselliaceae Genus of bacteria

Thorselliaceae is a family of bacteria belonging to the class Gammaproteobacteria and it was first described in February 2015. It is not assigned to an order. The family consists of four species in two genera. The bacteria are Gram-negative and rod shaped, approximately 1 μm wide and 2 μm long. They are facultative anaerobes and motile. Thorselliaceae bacteria have been found around the world associated with vector mosquitoes, mainly with vectors of malaria.

Saccharicrinis is genus of bacteria from the family of Marinilabiliaceae.

Plant microbiome

The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties. The term thus not only refers to the microorganisms involved but also encompasses their theatre of activity".
