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).
