The Burkholderiales are an order of Betaproteobacteria in the phylum Pseudomonadota.[3] Like all Pseudomonadota, they are Gram-negative. They include several pathogenic bacteria, including species of Burkholderia, Bordetella, and Ralstonia.[3] They also include Oxalobacter and related genera, which are unusual in using oxalic acid as their source of carbon.[3] Other well-studied genera include Alcaligenes, Cupriavidus, Achromobacter, Comamonas, Delftia, Massilia, Duganella, Janthinobacterium, Polynucleobacter (important freshwater bacterioplankton), non-pathogenic Paraburkholderia, Caballeronia, Polaromonas, Thiomonas, Collimonas, Hydrogenophaga, Sphaerotilus, Variovorax, Acidovorax, Rubrivivax and Rhodoferax (both members of the photosynthetic purple nonsulfur bacteria), and Herbaspirillum (capable of nitrogen-fixation).
