Variovorax is a Gram-negative and motile genus of bacteria from the family Comamonadaceae. It belongs to the class called Betaproteobacteria. [1] [2] [3] It is an aerobic bacteria and most of its species is found in soil and freshwater. [4] The demographic distribution of this species is primarily in Europe, Asia and the Americas, as well as the polar regions. [5] Its designated species is Variovorax paradoxus which arose from the species Alcaligenes paradoxus being grouped under the Variovorax genus. [6] Variovorax paradoxus constitutes to the methylotrophic microbiota of the human mouth. [7]

    The Variovorax genus is known for producing enzymes that break down acyl-homoserine lactones (AHLs), which play an essential role in quorum sensing.[1] Thus, these bacteria assist in quorum quenching through the enzymatic inactivation of AHL signals.[1] This genus is a growth-promoting rhizobacteria that partners with plants and provides mutually beneficial interactions.[2]Variovorax is known for its ability to metabolize aromatic compounds.[3] In 2024, a new species, Variovorax durovernensis, was identified as the source of a patient’s bloodstream infection.[4]
