Sphingomonadales Yabuuchi and Kosako 2006
General information
Description and emendation
Gram-negative, nonsporeforming rod-shaped, ovoid, or pleomorphic cells. Reproduction is usually by binary fission, but in some members, polar growth or budding has been observed by electron microscopy. Motile or nonmotile. Instead of lipopolysaccharide (LPS) in cell wall, glucuronosyl ceramide (SGL-1) and 2-OH myristic acid are present, without 3-OH acids. Instead of C14:0 2OH nonhydroxy myristic acid in Zymomonas mobilis. Aerobic, having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor, with the exception of the genus Zymomonas, which is facultatively anaerobic and has a strictly fermentative type of metabolism. Some species synthesize bacteriochlorophyll a and are facultative phototrophs. Chemoheterotrophic. The major respiratory quinone is ubiquinone Q-10 in those genera that have been tested. Belong to the class Alphaproteobacteria. Free living and widely distributed in nature. The mol% G+C of the DNA is: 59-68.5; (Z. mobilis, 49.1).
