Deltaproteobacteria

Definition
noun
A taxonomic class in Phylum Proteobacteria that includes diverse species such as myxospore-forming bacteria (i.e. Myxobacteria), sulfate-reducing bacteria (e.g. Desulfovibrio, Desulfobacter, etc.), sulfur-reducing bacteria (i.e. Desulfuromonas), ferric iron-reducing bacteria (i.e. Geobacter), etc.
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.
Deltaproteobacteria is a taxonomic class of predominantly aerobic, gram-negative species. Many genera of this class are essential contributors to the sulfur cycle (e.g. Desulfovibrio, Desulfobacter, Desulfuromonas, etc.).
Some of the taxonomic orders belonging to this class are as follows:

  • Bdellovibrionales (e.g. Bdellovibrio )
  • Desulfobacterales (Sulfate-reducing bacteria, e.g. Desulfobacter)
  • Desulfovibrionales (e.g. Desulfovibrio)
  • Desulfurellales (e.g. Desulfurella)
  • Desulfuromonadales (e.g. Geobacter, Pelobacter, etc.)
  • Myxococcales (myxobacteria, e.g. Myxococcus xanthus, Stigmatella aurantiaca)
  • Syntrophobacterales (e.g. Thermaerobacter)

Scientific classification:

  • Domain: Bacteria
  • Phylum: Proteobacteria
