The Chromatiales are an order of Gammaproteobacteria within Pseudomonadota. Like other Proteobacteria, the Chromatiales are Gram-negative and can be spherical, vibrioid, spiral or rod-shaped.[2]
Classification
Some members of the order comprise the primarily anaerobic and phototrophic purple sulfur bacteria (PSBs), found specifically within the families Chromatiaceae and Ectothiorhodospiraceae. Other members, like those in the families Halothiobacillaceae and Thioalkalibacteraceae, are aerobic and chemolithoautotrophic.
