The Rhodospirillales is an order of Proteobacteria, with two families: the Acetobacteraceae and the Rhodospirillaceae.
The Acetobacteraceae comprise the acetic acid bacteria, which are heterotrophic and produce acetic acid during their respiration. The Rhodospirillaceae include mainly purple non-sulfur bacteria, which produce energy through photosynthesis.
