Sphingomonadaceae Kosako et al. 2000
General information
Description and emendation
The organisms of the family are Gram-negative, asporogenous rods or ovoid cells. They divide by binary division, budding or asymmetric division, and can be observed by electron microscopy in S. natatoria and S. ursincola. Aerobic or facultative anaerobic chemoorganotrophs. The cells of some genus contain bacterichlorophyll a (Bchl a) and are facultative photoorganotrophs. Colony color is different from species to species such as deep yellow, orange, brown-orange, faint yellow, creamy-yellow or non-pigmented. Motile by means of polar flagella. The major fatty acids of cellular lipids are octadecenoic acid (18:1) and 2-hydroxymyristic acid (2-OH 14:0) (with the exception of two subspecies of Zymomonas mobilis). Ubiquinone-10 (Q-10) is the major respiratory quinone. N-2'-hydroxymyristoyl dihydrosphingosine 1-glucuronic acid (SGL-1) is the major sphingoglycolipid in the cellular lipids. The G+C content of the DNA ranges from 47.5 to 67.0 mol%. The 16S rDNA signature pattern for the family consists of 105-116 (C-C), 433-442 (G-C), 750-754 (T-C), 855-858 (G-G), 1334-1336 (G-C) and 1385 (G). The present members of the family Sphingomonadaceae are Sphingomonas, Erythrobacter, Erythromicrobium, Porphyrobacter, Sandaracinobacter, and Zymomonas. They are commonly isolated from soil, activated sludge or marine environment, sick cider, sugar cane juice and from clinical specimens.
