Pseudomonadota, the Caulobacteraceae are
gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wa ...

Caulobacteraceae includes the genera ''
Asticcacaulis'', ''
Brevundimonas'', ''
Phenylobacterium'' and ''
Caulobacter''.
The typespecies ''Caulobacter'' gives its name also to the recently proposed subclass, the ''Caulobacteridae'', which includes the orders ''Caulobacterales'', ''
Parvularculales
The "''Parvularculaceae''" are a family of marine bacteria.
