Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
The Burkholderiaceae are a family of bacteria included in the order Burkholderiales. It includes some pathogenic species, such as Burkholderia mallei (glanders) and Burkholderia pseudomallei (melioidosis). This family was found to be enriched in scale-eating pupfish guts, even after being fed a common laboratory diet, suggesting it may aid in scale-digestion.
Filamentation is the anomalous growth of certain bacteria, such as Escherichia coli, in which cells continue to elongate but do not divide. The cells that result from elongation without division have multiple chromosomal copies.
Beggiatoa is a genus of Gammaproteobacteria belonging to the order Thiotrichales, in the Pseudomonadota phylum. This genus was one of the first bacteria discovered by Ukrainian botanist Sergei Winogradsky. During his research in Anton de Bary's laboratory of botany in 1887, he found that Beggiatoa oxidized hydrogen sulfide (H2S) as an energy source, forming intracellular sulfur droplets, with oxygen as the terminal electron acceptor and CO2 used as a carbon source. Winogradsky named it in honor of the Italian doctor and botanist Francesco Secondo Beggiato (1806 - 1883), from Venice. Winogradsky referred to this form of metabolism as "inorgoxidation" (oxidation of inorganic compounds), today called chemolithotrophy. These organisms live in sulfur-rich environments such as soil, both marine and freshwater, in the deep sea hydrothermal vents and in polluted marine environments. The finding represented the first discovery of lithotrophy. Two species of Beggiatoa have been formally described: the type species Beggiatoa alba and Beggiatoa leptomitoformis, the latter of which was only published in 2017. This colorless and filamentous bacterium, sometimes in association with other sulfur bacteria (for example the genus Thiothrix), can be arranged in biofilm visible to the naked eye formed by a very long white filamentous mat, the white color is due to the stored sulfur. Species of Beggiatoa have cells up to 200 µm in diameter and they are one of the largest prokaryotes on Earth.
Paraburkholderia kururiensis is a species of bacteria.
Paraburkholderia sacchari is a species of bacteria in the phylum Pseudomonadota. It was isolated in the 1990s from sugarcane crop soil, and later identified as a new bacterial species, originally named as Burkholderia sacchari. Paraburkholderia sacchari was found to be capable of creating and accumulating polyhydroxyalkanoates (PHA) by incorporating different monomers. This strain was subject of a number of genetic and bioproccess engineering studies conducted worldwide aiming to establish PHA production from different substrates, especially using agro-industrial byproducts.
Alicyclobacillus is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures.
Agromyces is a genus in the phylum Actinomycetota (Bacteria).
Paraburkholderia ginsengisoli is a gram-negative, rod-shaped, motile bacterium with unipolar polytrichous flagella from the genus Paraburkholderia and the family Burkholderiaceae which was isolated from soil of a ginseng field in South Korea. Paraburkholderia ginsengisoli has the ability to produce β-glucosidase.
Paraburkholderia oxyphila is a gram-negative, aerobic, non-spore-forming, non motile, rod-shaped bacterium from the genus Paraburkholderia and the family Burkholderiaceae which was isolated from acidic forest soil.
Paraburkholderia rhizoxinica is a gram-negative, oxidase and catalase-positive, motile bacterium from the genus Paraburkholderia and the family Burkholderiaceae which was isolated from the plant pathogenic fungus, Rhizopus microsporus. The complete genome of Paraburkholderia rhizoxinica is sequenced.
Paraburkholderia terrae is a Gram-negative, nitrogen-fixing, catalase and oxidase-positive, motile bacterium with a single polar flagellum, from the genus Paraburkholderia and family Burkholderiaceae, which was isolated from a forest soil in Daejeon in South Korea.
Paraburkholderia denitrificans is a gram-negative, bacterium from the genus Paraburkholderia and the family Burkholderiaceae which was isolated from wet forest soil on the island of Liancourt Rocks. Paraburkholderia denitrificans has the ability to reduced nitrate to nitrogen gas.
Caballeronia humi is a Gram-negative, aerobic, non-motile bacterium from the genus Burkholderia and the family Burkholderiaceae which was isolated from peat soil in Russia.
Caballeronia udeis is a bacterium from the genus Caballeronia and family Burkholderiaceae which has been reported to perform biological nitrogen fixation and promote plant growth
Paraburkholderia rhizosphaerae is a bacterium from the genus of Paraburkholderia which has been isolated from rhizosphere soil in Daejeon in Korea.
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.
Caballeronia is a genus of bacteria from the family of Burkholderiaceae which has been reported to perform biological nitrogen fixation and promote plant growth
Paraburkholderia madseniana is a Gram-negative bacterium belonging to the genus Paraburkholderia. The type strain is P. madseniana RP11T, which was isolated from forest soil near Ithaca, NY, in 2016. The species was named in honor of Gene Madsen, a Professor at Cornell University, in recognition of his contributions to the field of environmental microbiology. The species is notable for its capacity to degrade phenolic compounds and its involvement in the priming effect.
Paraburkholderia solitsugae is a Gram-negative bacterium belonging to the genus Paraburkholderia. The type strain, P. solitsugae 1NT, was isolated from the Arnot research forest at the same time as Paraburkholderia elongata, using agar medium supplemented with soil-extracted, solubilized organic matter. P. solitsugae was named after the 'soil of hemlock trees' from which it was isolated. According to the aforementioned studies, P. solitsugae is a fast-growing, metabolically versatile bacteria and possesses the capability to degrade aromatic acids.
