Betaproteobacteria

Definition
noun
A taxonomic class in the phylum Proteobacteria that includes species such as chemolithotrophic proteobacteria (e.g. Nitrosomonas), phototrophs (e.g. Rhodocyclus), and pathogens (e.g. Neisseria and Bordetella)
Supplement
Proteobacteria is a phylum of the domain Bacteria that includes a great diversity of forms of species. This phylum has six taxonomic classes: (1) Alphaproteobacteria, (2) Betaproteobacteria, (3) Gammaproteobacteria, (4) Deltaproteobacteria, (5) Epsilonproteobacteria, and (6) Zetaproteobacteria.
Betaproteobacteria is a class of bacteria in the phylum Proteobacteria. Similar to other classes of the phylum, Betaproteobacteria are gram-negative and consist of diverse groups of bacteria. Some of them are chemolithotrophs (e.g. Nitrosomas spp.); others are phototrophs (Rhodocyclus spp. and Rubrivivax spp.). There are also pathogenic species, e.g. Neiserria spp. (causing gonorrhea and meningitis) and Bordetella pertussis (causing whooping cough).
Some of the taxonomic orders of the class Betaproteobacteria are as follows:

  • Burkholderiales (e.g. Burkholderia, Bordetella, Ralstonia, etc.)
  • Hydrogenophilales (e.g. Hydrogenophilus sp.)
  • Methylophilales (e.g. Methylobacillus sp.)
  • Neisseriales (e.g. Neisseria, Chromobacterium, Vitreoscilla, etc.)
  • Nitrosomonadales (e.g. Nitrosomonas, Spirillum, etc.)
  • Rhodocyclales (e.g. Azoarcus, Rhodocyclus, Zoogloea, etc.)

Scientific classification:

  • Domain: Bacteria
  • Phylum: Proteobacteria
  • Class: Betaproteobacteria
