Sphingopyxis granuli is a Gram-negative alphaproteobacterium in the family Sphingomonadaceae, characterized by its yellow-pigmented colonies and the presence of sphingolipids in its membrane—a trait shared across the family. It was isolated from granule-associated material and is aerobic, rod-shaped, and motile. Sphingopyxis species are common in soils, freshwater, and plant-associated environments.
