Paracoccus is a genus of bacteria in the family Paracoccaceae and is the type genus of that family.[1] The type species is Paracoccus denitrificans.[1] Members are generally Gram-negative cocci or short rods and exhibit diverse metabolic capabilities; species include aerobic heterotrophs, methylotrophs, sulfur oxidizers, and denitrifiers.[2]

Taxonomy

The genus was established to accommodate the Gram-negative, coccoid hydrogen bacterium then known as Micrococcus denitrificans, which became P. denitrificans.[3] Thiosphaera is treated as a heterotypic synonym of Paracoccus following the transfer of its type species into Paracoccus.[4] The genus was formerly assigned to Rhodobacteraceae; it is currently placed in Paracoccaceae.[1]
