Sphingopyxis

Sphingomonas is one of the four genera of sphingomonads.

Sphingomonas alaskensis and S. flavimarisis are the dominant bacteria in some marine oligotrophic environments. S. chilensis degrades chlorophenol. S. macrogoltabida and S. terrae degrade polyethylene glycol, and S. witflariensis was isolated from activated sludge.
