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.^[2][3] 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.^[4][5][6]
