Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcota phylum. According to comparative analysis of 16S rRNA, this is one the most ancient group of bacteria Thermus species can be distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of eight conserved signature indels found in proteins such as adenylate kinase and replicative DNA helicase as well as 14 conserved signature proteins that are exclusively shared by members of this genus.
Rhodococcus is a genus of aerobic, nonsporulating, nonmotile Gram-positive bacteria closely related to Mycobacterium and Corynebacterium. While a few species are pathogenic, most are benign, and have been found to thrive in a broad range of environments, including soil, water, and eukaryotic cells. Some species have large genomes, including the 9.7 megabasepair genome of Rhodococcus sp. RHA1.
Pseudomonas gessardii is a fluorescent, Gram-negative, rod-shaped bacterium isolated from natural mineral waters in France. Based on 16S rRNA analysis, P. gessardii has been placed in the P. fluorescens group.
Delftia acidovorans is a Gram-negative, motile, non-sporulating, rod-shaped bacterium known for its ability to biomineralize gold and bioremediation characteristics. It was first isolated from soil in Delft, Netherlands. The bacterium was originally categorized as Pseudomonas acidovorans and Comamonas acidovorans before being reclassified as Delftia acidovorans.
Comamonas testosteroni is a Gram-negative environmental bacterium capable of utilizing testosterone as a carbon source, and degrading other sterols such as ergosterol and estrogens. Strain I2gfp has been used in bioaugmentation trials, in attempts to treat the industrial byproduct 3-chloroaniline. It was first classified as a human pathogen in 1987 according to the National Library of Medicine. A number of strains of Comamonas, including C. testosteroni, have been shown to consume terephthalic acid, one of the components of PET plastic, as a sole carbon source.
Lysinibacillus sphaericus is a Gram-positive, mesophilic, rod-shaped bacterium commonly found on soil. It can form resistant endospores that are tolerant to high temperatures, chemicals and ultraviolet light and can remain viable for long periods of time. It is of particular interest to the World Health Organization due to the larvicide effect of some strains against two mosquito genera, more effective than Bacillus thuringiensis, frequently used as a biological pest control. L. sphaericus cells in a vegetative state are also effective against Aedes aegypti larvae, an important vector of yellow fever and dengue viruses.
The genus Massilia is an outdated genus name of bacteria within the family Oxalobacteriaceae. All Massilia species were reclassified in 2023 into one of the following genera: Duganella, Pseudoduganella, Janthinobacterium,Telluria,Rugamonas,Mokoshia, or Zemynaea.
Collimonas is a genus of bacteria in the family Oxalobacteraceae. Culturable representatives of this genus have the ability to lyse chitin, to use fungal hyphae as a source of food, to produce antifungal molecules and to be effective at weathering.
Halomonas titanicae is a gram-negative, halophilic species of bacteria which was isolated in 2010 from rusticles recovered from the wreck of the RMS Titanic. It has been estimated by Henrietta Mann, one of the researchers that first isolated it, that the action of microbes like Halomonas titanicae may bring about the total deterioration of the Titanic by 2030. While the bacteria have been identified as a potential danger to oil rigs and other man-made objects in the deep sea, they also have the potential to be used in bioremediation to accelerate the decomposition of shipwrecks littering the ocean floor.
Delftia tsuruhatensis is a Gram-negative, rod-shaped, catalase- and oxidase-positive, motile bacterium from the Comamonadaceae family. It was first isolated from a wastewater treatment plant in Japan in 2003. D. tsuruhatensis is an opportunistic and emergent pathogen. All documented human infections are healthcare-associated.
Delftia lacustris is a Gram-negative, nonfermentative, motile, rod-shaped bacterium from the family Comamonadaceae, which was isolated from mesotrophic lake water in Denmark. It has the ability to degrade peptidoglycan through chitinase and lysozyme activity.
Cupriavidus pauculus is a Gram-negative, nonfermentative, motile bacterium of the genus Cupriavidus and family Burkholderiaceae isolated from water from ultrafiltration systems and bottled mineral water. C. pauculus is associated with human infections.
Akkermansia muciniphila is a human intestinal symbiont, isolated from human feces. It is a mucin-degrading bacterium belonging to the genus, Akkermansia, discovered in 2004 by Muriel Derrien and Willem de Vos at Wageningen University of the Netherlands. It belongs to the phylum Verrucomicrobiota and its type strain is MucT. It is under preliminary research for its potential association with metabolic disorders.
Acetivibrio straminisolvens is a moderately thermophilic, aerotolerant and cellulolytic bacterium. It is non-motile, spore-forming, straight or slightly curved rod, with type strain CSK1T. Its genome has been sequenced.
Azospirillum is a Gram-negative, microaerophilic, non-fermentative and nitrogen-fixing bacterial genus from the family of Rhodospirillaceae. Azospirillum bacteria can promote plant growth.
Chthonobacter is a genus of bacteria from the order Hyphomicrobiales with one valid species.
Herbihabitans rhizosphaerae is a bacterium from the genus Herbihabitans which has been isolated from rhizosphere soil from the plant Limonium sinense in Xinjiang, China.
Salisediminibacterium is a genus of Gram-positive bacteria from the family of Bacillaceae. The type species is Salisediminibacterium halotolerans.
Sphingobacterium olei is a Gram-stain-negative, rod-shaped, and non-motile bacterium. It was first isolated from oil-contaminated soil in Daqing oil field, China. S. olei has been found to be able to degrade herbicides quizalofop-p-ethyl and diclofop-methyl. Before a name was given, S. olei was designated as strain HAL-9T. The species name olei means "of oil" in Latin.
