(noun)

Betaproteobacteria is a class of Proteobacteria. Betaproteobacteria are, like all Proteobacteria, Gram-negative.

Examples of Betaproteobacteria in the following topics:

  • Betaproteobacteria

    • The Betaproteobacteria consist of several groups of aerobic or facultative bacteria that are often highly versatile in their degradation capacities, but also contain chemolithotrophic genera (e.g., the ammonia-oxidising genus Nitrosomonas) and some phototrophs (members of the genera Rhodocyclus and Rubrivivax).
    • Betaproteobacteria play a role in nitrogen fixation in various types of plants, oxidizing ammonium to produce nitrite- an important chemical for plant function.

  • Overview of Proteobacteria

    • The alpha, beta, delta, epsilon sections are monophyletic, but the Gammaproteobacteria due to the Acidithiobacillus genus is paraphyletic to Betaproteobacteria, according to multigenome alignment studies, which if done correctly are more precise than 16S (note that Mariprofundus ferrooxydans sole member of the Zetaproteobacteria was previously misclassified on NCBI taxonomy).
    • These classes include: Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Deltaproteobacteria, Epsilonproteobacteria and Zetaproteobacteria.

  • Alphaproteobacteria

    • Phylogenetic analyses and conserved indels in large numbers of other proteins provide evidence that Alphaproteobacteria have branched off later than most other phyla and Classes of Bacteria with the exception of Betaproteobacteria and Gammaproteobacteria.
