Acidobacteria is a phylum of bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
Sphingomonadaceae are a gram-negative bacterial family of the Alphaproteobacteria. An important feature is the presence of sphingolipids in the outer membrane of the cell wall. The cells are ovoid or rod-shaped. Others are also pleomorphic, i.e. the cells change the shape over time. Some species from Sphingomonadaceae family are dominant components of biofilms.
Delftia is a genus of Gram-negative bacteria that was first isolated from soil in Delft, Netherlands. The species is named after both the city, and in honor of pioneering research in the field of bacteriology that occurred in Delft. Cells in the genus Delftia are rod shaped and straight or slightly curved. Cells occur singly or in pairs, are 0.4–0.8ɥM wide and 2.5–4.1ɥM long. Delftia are motile by flagella, non-sporulating, and chemo-organotrophic.
Sphingomonas paucimobilis is a strictly aerobic Gram-negative bacterium that has a single polar flagellum with slow motility. The cell size is around 0.7 x 1.4 μm. It is usually found in soil. As with the other members of the genus, its biochemistry is remarkable in possession of ubiquinone 10 as its major respiratory quinone, and of glycosphingolipids instead of lipopolysaccharides in its cell envelope. It has been implicated in various types of clinical infections.
Sphingomonas yanoikuyae is a short rod-shaped, strictly aerobic, Gram-negative, non-motile, non-spore-forming, chemoheterotrophic species of bacteria that is yellow or off-white in color. Its type strain is JCM 7371. It is notable for degrading a variety of aromatic compounds including biphenyl, naphthalene, phenanthrene, toluene, m-, and p-xylene. S. yanoikuyae was discovered by Brian Goodman on the southern coast of Papua New Guinea. However, Sphingomonas have a wide distribution across freshwater, seawater, and terrestrial habitats. This is due to the bacteria’s ability to grow and survive under low-nutrient conditions as it can utilize a broad range of organic compounds.
Sphingomonas wittichii is a species of bacteria. It was first isolated from water of the River Elbe. Its type strain is DSM 6014T. It is notable for metabolising dibenzo-p-dioxin and phenazine-1-carboxylic acid.
Alcanivorax dieselolei is a species of alkane-degrading bacteria. Its genome has been sequenced. It is halophilic, aerobic, Gram-negative, non-spore-forming, catalase- and oxidase-positive, motile and rod-shaped. Its type strain is B-5T.
Syntrophobacter fumaroxidans is a species of syntrophic propionate-degrading sulfate-reducing bacterium. Strain MPOBT is the type strain. Its genome has been fully sequenced.
Holophaga foetida is a bacterium, the type species of its genus. It is a homoacetogenic bacterium degrading methoxylated aromatic compounds. It is gram-negative, obligately anaerobic and rod-shaped, with type strain TMBS4. Its genome has been sequenced. It is known for its ability to anaerobically degrade aromatic compounds and the production of volatile sulfur compounds through a unique pathway.
Novosphingobium pentaromativorans is a species of high-molecular-mass polycyclic aromatic hydrocarbon-degrading bacterium. It is Gram-negative, yellow-pigmented and halophilic. With type strain US6-1T. Its genome has been sequenced.
Oleispira antarctica is a hydrocarbonoclastic marine bacterium, the type species in its genus. It is psychrophilic, aerobic and Gram-negative, with polar flagellum. Its genome has been sequenced and from this information, it has been recognized as a potentially important organism capable of oil degradation in the deep sea.
Sphingomonas aromaticivorans is a species of bacteria. It is an aromatic compound-degrading bacteria, it is gram-negative, non-spore-forming, non-motile and rod-shaped. It is found in deep-terrestrial-subsurface sediments.
