Sphingomonadaceae
Template:Short description Template:Automatic taxobox
Sphingomonadaceae are a gram-negative bacterial family of the Alphaproteobacteria. An important feature is the presence of sphingolipids (mainly 2′-hydroxymyristoyl dihydrosphingosine 1-glucuronic acid, "SGL-1") in the outer membrane of the cell wall.[1][2] 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.[3][4][5]
Energy source
While most species within Sphingomonadaceae family are heterotrophic,[6] some are phototrophic.
Function
Some species of Sphingomonadaceae are known to degrade some aromatic compounds. This makes the bacteria of interest to environmental remediation.[7]
The diverse metabolic capacity of genera within the Sphingomonadaceae family, such as Sphingobium, Novosphingobium,Template:Efn and Sphingopyxis enable these genera to adapt to and be abundant in the presence of bisphenol A. A microbial community with abundant Sphingomonadaceae members can degrade bisphenol A with a constant rate.[8]
Some Sphingomonas species are able to produce sphingans, a kind of exopolysaccharides with certain viscosity. This property of sphingans makes it useful in many industries including food and pharmaceutical.[9][6]
Distribution
Bacteria within Sphingomonadaceae family are distributed in various environments, such as water,[4] soil,[10][11] sediment.[6][12]
Phylogeny
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature[13] and the phylogeny is based on whole-genome sequences.[14]Template:Efn

Interaction with human and plants
Some members of the Sphingomonadaceae commonly exist in human-impacted environments, including drinking water systems,[15][4] hospital and household tap water,[16] and medical devices.[17][18][19]
Most of the species of the Sphingomonadaceae are not known to be harmful to humans or plants.[6] Some species can protect plants from disease-causing pathogens such as Thielaviopsis basicola, and Rhizoctonia solani.[6][11][10][20]
The Sphingomonas and Sphingobium genera tend to have higher antibiotic resistance compared with three other genera within the Sphingomonadaceae: Novosphingobium,Template:Efn Sphingopyxis, and Blastomonas.[4]
